In this prospectus, unless the context otherwise requires:

We filed a registration statement on Form S-1 with the SEC on March 15, 2010, as amended, with respect to the initial public offering of the common stock of MagnaChip Corporation, which we refer to as the MagnaChip Corporation IPO. If and when we decide to proceed with the MagnaChip Corporation IPO, prior to the effectiveness of the registration statement filed with the SEC for the MagnaChip Corporation IPO, we will complete a number of transactions pursuant to which MagnaChip Corporation will succeed to the business of MagnaChip Semiconductor LLC, the members of MagnaChip Semiconductor LLC will become stockholders of MagnaChip Semiconductor Corporation and all of the outstanding options and warrants to purchase common units of MagnaChip Semiconductor LLC will be automatically converted into options and warrants to purchase shares of MagnaChip Corporation’s common stock. In this prospectus, we refer to such transactions as the corporate conversion.

Neither of the co-issuers has any material operations and the financial statements and other financial information, as well as Management’s Discussion and Analysis of Financial Condition and Results of Operations, contained in this prospectus relate to the consolidated financial statements and other consolidated information of MagnaChip. For this reason, the description of our business operations elsewhere relates to the operations of our consolidated group.

Overview

MagnaChip is a Korea-based designer and manufacturer of analog and mixed-signal semiconductor products for high-volume consumer applications. We believe we have one of the broadest and deepest analog and mixed-signal semiconductor technology platforms in the industry,

supported by our 30-year operating history, large portfolio of approximately 2,655 novel registered patents and 900 pending novel patent applications, and extensive engineering and manufacturing process expertise. Our business is comprised of three key segments: Display Solutions, Power Solutions and Semiconductor Manufacturing Services. Our Display Solutions products include display drivers that cover a wide range of flat panel displays and mobile multimedia devices. Our Power Solutions products include discrete and integrated circuit solutions for power management in high- volume consumer applications. Our Semiconductor Manufacturing Services segment provides specialty analog and mixed-signal foundry services for fabless semiconductor companies that serve the consumer, computing and wireless end markets.

Our wide variety of analog and mixed-signal semiconductor products and manufacturing services combined with our deep technology platform allows us to address multiple high-growth end markets and to rapidly develop and introduce new products and services in response to market demands. Our substantial manufacturing operations in Korea and design centers in Korea and Japan place us at the core of the global consumer electronics supply chain. We believe this enables us to quickly and efficiently respond to our customers’ needs and allows us to better service and capture additional demand from existing and new customers.

We have a long history of supplying and collaborating on product and technology development with leading innovators in the consumer electronics market. As a result, we have been able to strengthen our technology platform and develop products and services that are in high demand by our customers and end consumers. We sold over 1,900 and 2,300 distinct products to over 335 and 185 customers for the six months ended June 30, 2010 and combined twelve-month period ended December 31, 2009, respectively, with a substantial portion of our revenues derived from a concentrated number of customers. The increase in number of customers is due to the continuing growth of our Power Solutions business. Our largest semiconductor manufacturing services customers include some of the fastest growing and leading semiconductor companies that design analog and mixed-signal products for the consumer, computing and wireless end markets.

Our business is largely driven by innovation in the consumer electronics markets and the growing adoption by consumers worldwide of electronic devices for use in their daily lives. The consumer electronics market is large and growing rapidly, largely due to consumers increasingly accessing a wide variety of available rich media content, such as high definition audio and video, mobile television and games on advanced consumer electronic devices. According to Gartner, production of liquid crystal display, or LCD televisions, smartphones, mobile personal computers, or PCs, and mini-notebooks is expected to grow from 2009 to 2013 by a compound annual growth rate of 12%, 36%, 24%, and 20%, respectively. Electronics manufacturers are continuously implementing advanced technologies in new generations of electronic devices using analog and mixed-signal semiconductor components, such as display drivers that enable display of high resolution images, encoding and decoding devices that allow playback of high definition audio and video, and power management semiconductors that increase power efficiency, thereby reducing heat dissipation and extending battery life. According to iSuppli Corporation, in 2009, the display driver semiconductor market was $6.0 billion and the power management semiconductor market was $21.9 billion.

For the six months ended June 30, 2010, on a pro forma basis, we generated net sales of $374.2 million, loss from continuing operations of $3.8 million, Adjusted EBITDA of $72.6 million and Adjusted Net Income of $40.6 million. For 2009 on a combined pro forma basis, we generated net sales of $560.1 million, income from continuing operations of $46.6 million, Adjusted EBITDA of $98.7 million and Adjusted Net Income of $33.7 million. On June 12, 2009, we filed a voluntary petition for relief under Chapter 11 of the United States Bankruptcy Code and our plan of reorganization became

effective on November 9, 2009. For 2008, we generated net sales of $601.7 million, losses from continuing operations of $325.8 million, Adjusted EBITDA of $59.8 million and Adjusted Net Loss of $71.7 million. See “Unaudited Pro Forma Consolidated Financial Information” beginning on page 56 for an explanation regarding our pro forma presentation and “Prospectus Summary—Summary Historical and Unaudited Pro Forma Consolidated Financial Data,” beginning on page 17 for an explanation of our use of Adjusted EBITDA and Adjusted Net Income.

Our Products and Services

Our Display Solutions products include source and gate drivers and timing controllers that cover a wide range of flat panel displays used in LCD televisions and light emitting diode, or LED, televisions and displays, mobile PCs and mobile communications and entertainment devices. Our display solutions support the industry’s most advanced display technologies, such as low temperature polysilicon, or LTPS, and active matrix organic light emitting diode, or AMOLED, as well as high-volume display technologies such as thin film transistor, or TFT. Our Display Solutions business represented 50.5%, 50.5% and 46.7% of our net sales for the fiscal years ended December 31, 2009 (on a combined basis), 2008 and 2007, respectively, and 42.0% and 55.5% of our net sales for the six months ended June 30, 2010 and June 28, 2009, respectively.

We expanded our business and market opportunity by establishing our Power Solutions business in late 2007. We have introduced a number of products for power management applications, including metal oxide semiconductor field effect transistors, or MOSFETs, analog switches, LED drivers, DC-DC converters and linear regulators for a range of devices, including LCD and LED digital televisions, mobile phones, computers and other consumer electronics products. Our Power Solutions business represented 2.2% and 0.9% of our net sales for the fiscal years ended December 31, 2009 (on a combined basis) and 2008, respectively, and 5.6% and 1.1% of our net sales for the six months ended June 30, 2010 and June 28, 2009, respectively.

We offer semiconductor manufacturing services to fabless analog and mixed-signal semiconductor companies that require differentiated, specialty analog and mixed-signal process technologies. We believe the majority of our top twenty semiconductor manufacturing services customers use us as their primary manufacturing source for the products that we manufacture for them. Our process technologies are optimized for analog and mixed-signal devices and include standard complementary metal-oxide semiconductor, or CMOS, high voltage CMOS, ultra-low leakage high voltage CMOS and bipolar complementary double-diffused metal oxide semiconductor, or BCDMOS. Our semiconductor manufacturing services customers use us to manufacture a wide range of products, including display drivers, LED drivers, audio encoding and decoding devices, microcontrollers, electronic tags and power management semiconductors. Our Semiconductor Manufacturing Services business represented 46.7%, 47.7% and 45.2% of our net sales for the fiscal years ended December 31, 2009 (on a combined basis), 2008 and 2007, respectively, and 52.1% and 42.8% of our net sales for the six months ended June 30, 2010 and June 28, 2009, respectively.

We manufacture all of our products at our three fabrication facilities located in Korea. We have approximately 200 proprietary process flows we can utilize for our products and offer to our semiconductor manufacturing services customers. Our manufacturing base serves both our display driver and power management businesses and semiconductor manufacturing services customers, allowing us to optimize our asset utilization and leverage our investments across our product and service offerings. Analog and mixed-signal manufacturing facilities and processes are typically distinguished by design and process implementation expertise rather than the use of the most advanced equipment. These processes also tend to migrate more slowly to smaller geometries due to

technological barriers and increased costs. For example, some of our products use high-voltage technology that requires larger geometries and that may not migrate to smaller geometries for several years, if at all. As a result, our manufacturing base and strategy does not require substantial investment in leading edge process equipment, allowing us to utilize our facilities and equipment over an extended period of time with moderate required capital investments.

Our Competitive Strengths

We believe our strengths include:

Our Strategy

Our objective is to grow our business, our cash flow and profitability and to establish our position as a leading provider of analog and mixed-signal semiconductor products and services for high-volume markets. Our business strategy emphasizes the following key elements:

Recent Changes to Our Business

We have executed a significant restructuring over the last 18 months that refocused our business strategy, enhanced our operating efficiency and improved our cash flow and profitability. By closing our Imaging Solutions business, restructuring our balance sheet and refining our business processes and strategy, we believe we have made significant structural improvements to our operating model and have enabled better flexibility to manage our business through fluctuations in the economy and our markets.

Specifically, our business optimization initiatives included:

On April 9, 2010, we completed the sale of $250 million in aggregate principal amount of 10.500% senior notes due 2018, which we refer to as our senior notes. Of the $238.4 million of net proceeds, which represents $250 million of principal amount net of $3.3 million of original issue discount and $8.3 million of debt issuance costs, $130.7 million was used to make a distribution to our unitholders and $61.6 million was used to repay all outstanding borrowings under our term loan. The remaining proceeds of $46.1 million were retained to fund working capital and for general corporate purposes. As a result of our higher level of indebtedness from our senior notes offering, our interest expense will increase above that which was reported for the six months ended June 30, 2010 to approximately $13.6 million per semiannual period.

On June 30, 2010, we announced that we elected not to proceed with our planned MagnaChip Corporation IPO and corporate conversion at such time due to adverse market conditions. We intend to complete the MagnaChip Corporation IPO as soon as market conditions permit us to do so. We, however, cannot assure you when or if we will be able to complete the MagnaChip Corporation IPO, even if market conditions improve. If we are unable to complete the MagnaChip Corporation IPO, it could adversely impact the value of the notes.

Risks Related to Our Company

Investing in our company entails a high degree of risk, including those summarized below and those more fully described in the “Risk Factors” section beginning on page 24 of this prospectus before deciding whether to exchange your old notes in the exchange offer.

Corporate Information

MagnaChip Semiconductor LLC is a Delaware limited liability company and parent guarantor of the notes. MagnaChip Semiconductor LLC functions as a holding and financing company for other MagnaChip entities. On a stand-alone basis, MagnaChip Semiconductor LLC does not have any independent operations.

If and when we complete the MagnaChip Corporation IPO and prior to the effectiveness of the registration statement filed in connection with the MagnaChip Corporation IPO, MagnaChip Semiconductor LLC will convert from a Delaware limited liability company to a Delaware corporation. We refer to this as the corporate conversion. In connection with the corporate conversion, each common unit of MagnaChip Semiconductor LLC will be converted into shares of common stock of MagnaChip Semiconductor Corporation, the members of MagnaChip Semiconductor LLC will become stockholders of MagnaChip Semiconductor Corporation and MagnaChip Semiconductor Corporation will succeed to the business of MagnaChip Semiconductor LLC and its consolidated subsidiaries.

MagnaChip Semiconductor S.A., our Luxembourg subsidiary and one of the two co-issuers of the notes, is a Luxembourg public limited liability company (société anonyme). It functions as a financing company. On a stand-alone basis, MagnaChip Semiconductor S.A. does not have any independent operations.

MagnaChip Semiconductor Finance Company, a wholly-owned subsidiary of MagnaChip Semiconductor S.A. and one of the two co-issuers of the notes, is a Delaware corporation. On a stand-alone basis, MagnaChip Semiconductor Finance Company does not have any independent operations.

Our principal executive offices are located at c/o MagnaChip Semiconductor S.A., 74, rue de Merl, B.P. 709 L-2146 Luxembourg R.C.S., Luxembourg B97483, and our telephone number is (352) 45-62-62. Our website address is www.magnachip.com. You should not consider the information contained on our website to be part of this prospectus.

Our business was named MagnaChip Semiconductor when it was acquired from Hynix Semiconductor, Inc., or Hynix, in October 2004. We refer to this acquisition as the Original Acquisition.

On June 12, 2009, MagnaChip Semiconductor LLC, along with certain of its subsidiaries, including MagnaChip Semiconductor S.A., filed a voluntary petition for relief in the United States Bankruptcy Court for the District of Delaware under Chapter 11 of the United States Bankruptcy Code, which we refer to as the reorganization proceedings. On November 9, 2009, our plan of reorganization became effective and we emerged from the reorganization proceedings with our management team remaining in place.

Our Chapter 11 plan of reorganization implemented a comprehensive financial reorganization that significantly reduced our outstanding indebtedness. Additionally, on that date, a new board of directors of MagnaChip Semiconductor LLC was appointed, MagnaChip Semiconductor LLC’s previously outstanding common and preferred units, and options were cancelled, MagnaChip Semiconductor LLC issued approximately 300 million common units and warrants to purchase 15 million common units to two classes of creditors and affiliated funds of Avenue Capital Management II, L.P. became the majority unitholder of MagnaChip Semiconductor LLC.

Avenue Capital Management II, L.P. is a global investment management firm, and it and its affiliated funds specialize in investing in high yield debt, debt of insolvent or financially distressed companies and equity of companies undergoing financial or operational turnarounds or reorganizations. In this prospectus, we refer to funds affiliated with Avenue Capital Management II, L.P. collectively as Avenue. Avenue generally does not manage or operate the companies in which it invests; however, in connection with some of its equity investments, Avenue will appoint one or more representatives to serve on the board of directors. Avenue was a holder of a significant portion of our indebtedness which was outstanding prior to our reorganization proceedings. In connection with our emergence from our reorganization proceedings, Avenue became our majority unitholder as a result of its participation in our rights offering and continued as a lender under our new term loan. In connection with our April 2010 old notes offering, Avenue purchased notes in the aggregate principal amount of $35.0 million, was repaid $42.8 million in connection with the repayment of our new term loan and received $91.2 million in connection with our distribution to unitholders. Avenue has the right to appoint a majority of our board pursuant to our Fifth Amended and Restated Limited Liability Company Operating Agreement and if and when we complete the MagnaChip Corporation IPO, Avenue will continue to be able to elect a majority of our board as long as Avenue continues to hold or control a majority of our outstanding shares. See “Certain Relationships and Related Transactions” for additional information. Because Avenue may be deemed to be our “affiliate,” based on interpretations by the staff of the SEC in no action letters issued to third parties not related to us, Avenue is not eligible to participate in the exchange offer with respect to the $35 million aggregate principal amount of old notes held by Avenue as of the date hereof. Pursuant to the terms of the exchange and registration rights agreement that we entered into with the initial purchasers in connection with the sale of the old notes, we have agreed to file and have declared effective a registration statement with the SEC on behalf of Avenue for the purpose of resale of the old notes by Avenue.

Organizational Structure

The following chart shows a summary of our organizational structure.

MagnaChip Semiconductor S. A. and MagnaChip Semiconductor Finance Company are the co-issuer of the old notes and the new notes offered hereby. MagnaChip Semiconductor LLC and each of its subsidiaries (other than MagnaChip Korea, the MagnaChip China Subsidiaries and certain Immaterial Subsidiaries (each as defined under the caption “Description of New Notes”)), guarantee the notes.

Summary of the Exchange Offer

On April 9, 2010, we completed the private offering of $250 million aggregate principal amount of 10.500% Senior Notes due 2018, which we refer to in this prospectus as the “old notes.” We entered into an exchange and registration rights agreement, which we refer to in this prospectus as the “notes registration rights agreement,” with the initial purchasers of the old notes in which we agreed to deliver to you this prospectus and to use all commercially reasonable efforts to complete an exchange offer within the time period specified in the notes registration rights agreement. Avenue purchased $35 million aggregate principal amount of old notes in the private offering. Because Avenue may be deemed to be our affiliate, they are not permitted to participate in the exchange offer and we have not included old notes held by them in this exchange offer. Below is a summary of the exchange offer. For a more detailed description of the exchange offer, see “Exchange offer.”

The terms of the new notes will be substantially identical to the terms of the old notes (including principal amount, interest rate, maturity and redemption rights), except that the new notes are registered under the Securities Act and will bear a separate CUSIP number, and the transfer restrictions, registration rights and related special interest terms applicable to the old notes will not apply to the new notes. The old notes may be exchanged only in denominations of $2,000 and integral multiples of $1,000. We intend by the issuance of the new notes to satisfy our obligations under the notes registration rights agreement.

If you are a broker-dealer and receive new notes for your own account in the exchange offer:

Summary of the Terms of New Notes

The exchange offer relates to the exchange of up to $215,000,000 in aggregate principal amount of old notes for an equal aggregate principal amount of new notes. There is currently $250 million in aggregate principal amount of old notes outstanding, of which $35 million are held by Avenue, who will not participate in the exchange offer. The terms of the new notes will be substantially identical to the terms of the old notes, except the new notes are registered under the Securities Act, the new notes will bear a separate CUSIP number, and the transfer restrictions, registration rights and related additional interest terms applicable to the old notes will not apply to the new notes. The new notes will evidence the same indebtedness as the old notes which they will replace. Both the old notes and the new notes are governed by the same indenture. The following summary contains some basic information about the new notes. For a more complete description of the new notes, see “Description of New Notes.”

The notes will be effectively subordinated in right of payment to all borrowings under future secured credit facilities (to the extent of the value of the collateral securing those facilities) and to all indebtedness and other liabilities (including trade payables) of any non-guarantor subsidiaries. Our non-guarantor subsidiaries generated approximately 98.0% and

The note guarantees will be the guarantors’ general unsecured obligations. Each guarantee will be effectively subordinated in right of payment to all future secured debt of the guarantor, will be pari passu in right of payment with all existing and future unsecured indebtedness and other liabilities (including trade payables) of the guarantor and senior in right of payment to any future subordinated indebtedness of the guarantor (if any).

In addition, at any time prior to April 15, 2013, we may on one or more occasions redeem up to 35% of the aggregate principal amount of the notes with the net cash proceeds of certain qualified equity offerings, at a redemption price equal to 110.500% of the principal amount of the notes to be redeemed plus accrued and unpaid interest and special interest, if any, to the redemption date.

Also, at any time prior to April 15, 2014, we may, on one or more occasions, redeem some or all of the notes at a redemption price equal to 100% of the principal amount of the notes redeemed, plus accrued and unpaid interest and special interest, if any, to the redemption date and a “make-whole” premium.

See “Description of New Notes—Optional Redemption.”

We may redeem the notes in whole but not in part, at our discretion, at a redemption price equal to the principal amount of the notes outstanding plus accrued and unpaid interest,

These covenants are subject to a number of important exceptions and qualifications. See “Description of New Notes—Certain Covenants.” Certain of these restrictive covenants will terminate if the notes are rated investment-grade.

Summary Historical and Unaudited Pro Forma Consolidated Financial Data

The following tables set forth summary historical and unaudited pro forma consolidated financial data of MagnaChip Semiconductor LLC on or as of the dates and for the periods indicated. The summary historical and unaudited pro forma consolidated financial data presented below should be read together with “Selected Historical Consolidated Financial and Operating Data,” “Unaudited Pro Forma Consolidated Financial Information,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and our audited and unaudited consolidated financial statements, including the notes to those consolidated financial statements, appearing elsewhere in this prospectus.

We have derived the summary historical consolidated financial data as of December 31, 2009 and 2008, and for the two-month period ended December 31, 2009, the ten-month period ended October 25, 2009 and the years ended December 31, 2008 and 2007 from the historical audited consolidated financial statements of MagnaChip Semiconductor LLC prepared in accordance with generally accepted accounting principles in the United States, or GAAP, included elsewhere in this prospectus. We have derived the summary historical consolidated financial data as of December 31, 2007 from the historical audited financial statements of MagnaChip Semiconductor LLC not included in this prospectus. We derived the unaudited consolidated statement of operations data for the six months ended June 30, 2010 and June 28, 2009, as well as unaudited consolidated balance sheet data as of June 30, 2010, from our unaudited interim consolidated financial statements included elsewhere in this prospectus. We derived the unaudited consolidated balance sheet data as of June 28, 2009 from our unaudited interim consolidated financial statements not included in this prospectus. The historical results of MagnaChip Semiconductor LLC for any prior period are not necessarily indicative of the results to be expected in any future period, and financial results for any interim period are not necessarily indicative of results for a full year.

In connection with our emergence from reorganization proceedings, we implemented fresh-start reporting, or fresh-start accounting, in accordance with applicable Accounting Standards Codification, or ASC 852 governing reorganizations. We elected to adopt a convenience date of October 25, 2009 (a month end for our financial reporting purposes) for application of fresh-start accounting. In accordance with the ASC 852 rules governing reorganizations, we recorded largely non-cash reorganization income and expense items directly associated with our reorganization proceedings including professional fees, the revaluation of assets, the effects of our reorganization plan and fresh-start accounting and write-off of debt issuance costs. As a result of the application of fresh-start accounting, our financial statements prior to and including October 25, 2009 represent the operations of our pre-reorganization predecessor company and are presented separately from the financial statements of our post-reorganization successor company. As a result of the application of fresh-start accounting, the financial statements prior to and including October 25, 2009 are not fully comparable with the financial statements for periods on or after October 26, 2009.

We have prepared the summarized unaudited pro forma financial data as of and for the six months ended June 30, 2010 and the combined twelve-month period ended December 31, 2009 to give pro forma effect to the reorganization proceedings and related events and the issuance of $250 million old notes and the application of the net proceeds therefrom, in each case as if they had occurred at January 1, 2009 with respect to consolidated statement of operations data. The summary unaudited pro forma financial data set forth below are presented for informational purposes only, should not be considered indicative of actual results of operations that would have been achieved had the reorganization proceedings and related events and the issuance of $250 million old notes and the application of the net proceeds therefrom been consummated on the dates indicated, and do not purport to be indicative of our results of operations for any future period.

We use Adjusted EBITDA in a number of ways, including:

The following table summarizes the adjustments to net income (loss) that we make in order to calculate Adjusted Net Income for the periods indicated:
