U.S. District Court Issues Verdict on TSMC-UniRAM Case

Hsinchu, Taiwan, R.O.C., September 26, 2007 — TSMC today announced that the United States District Court for the Northern District of California, San Francisco Division, awarded UniRAM Technologies US$30.5 million in litigation asserting that TSMC misused UniRAM’s alleged trade secrets. However, TSMC has the right to file post trial motions as well as to take appeal.

“TSMC has always held itself to the highest standards of respect for intellectual property, and believes that this verdict is in error,” said Dr. Dick Thurston, TSMC’s Vice President and General Counsel. “We intend to pursue all defenses vigorously.”
