Taipei, July 30 (CNA) The Supreme Court on Thursday rejected appeals by two former Taiwan Semiconductor Manufacturing Co. (TSMC) employees convicted in a trade secret leak case, making their sentences final. Another defendant, Lu Yi-yin (盧怡尹), an employee of Tokyo Electron Taiwan, is still appealing her conviction to the Supreme Court. Prosecutors said Chen Li-ming joined Tokyo Electron Taiwan, a supplier of semiconductor manufacturing equipment to TSMC, after leaving the chipmaker. Tokyo Electron Taiwan was also indicted for failing to properly supervise Chen. Investigators found that the company's cloud storage still contained TSMC trade secret materials during the investigation.
