The suit also asks for injunctive relief along with monetary damages. The complaint alleges that SMIC improperly obtained TSMC trade secrets and infringed TSMC patents. For example, the complaint states that SMIC hired over 100 TSMC employees and asked some of them to provide SMIC with TSMC's trade secrets. The suit alleges that a SMIC official asked a then-TSMC manager to obtain TSMC process information and forward it to SMIC. "We feel that we have no other choice than to proceed through the courts in order to protect our technology," said Dr. Dick Thurston, Vice President and General Counsel for TSMC. "It is our obligation to protect our patents and trade secrets to maintain shareholder value," Dr. Thurston explained. # # # About TSMC TSMC is the world's largest dedicated semiconductor foundry, providing the industry's leading process technology and the foundry industry's largest portfolio of process-proven library, IP, design tools and reference flows.
