Legal warning to TSMC from UMC

April 11, 2001 – Taipei – United Microelectronics Corp. has warned Taiwan Semiconductor Manufacturing that it may face legal action if it accepts orders from Silicon Integrated Systems Corp. (SIS).

SIS may soon decide on whether to order chipset capacity outsourcing from Taiwan Semiconductor (TSMC).

United is bringing a lawsuit against SIS in the US, claiming the firm has infringed on its intellectual property rights over its wafer-manufacturing process. United alleges SIS copied its 0.18-micron technology.

TSMC’s president, Tseng Fan-Chen, dismissed UMC’s warning and said that TSMC would welcome orders from any integrated device manufacturing companies, including SIS.
