Taiwan Semiconductor employees detained over trade secret theft

Investing.com -- Three people, including current and former employees of Taiwan Semiconductor Manufacturing Co., were detained on suspicion of illegally obtaining trade secrets related to core technologies, Taiwanese prosecutors said.

The Taiwan High Prosecutors Office announced the arrests following a four-day operation last month. The investigation began after TSMC (TPE:2330) proactively detected unusual access to employee files.

Authorities summoned and detained several suspects and searched their homes during the probe. Three suspects were found to have a high probability of violating Taiwan’s security law.

TSMC, the world’s largest contract chip maker, said Tuesday it conducted an internal investigation and has taken disciplinary action against employees involved in a potential leak of sensitive information that could undermine its technological leadership.

"TSMC recently detected unauthorized activities during routine monitoring, leading to the discovery of potential trade secret leaks," the company said.

The Taiwanese chip maker said it found the issue early and has initiated legal proceedings. It didn’t specify the exact technology involved.

TSMC said the case is now under judicial review, and it is unable to provide further details.
