Taiwanese prosecutors indicted a former deputy manager of Taiwan Semiconductor Manufacturing Company (TSMC) on Monday, July 20, 2026, for allegedly stealing trade secrets involving national core technologies. The stolen information is said to have been intended to support China's chip development efforts.

This indictment is the first case brought under Taiwan's National Security Act concerning attempts to advance Chinese semiconductor ambitions. Prosecutors reported that TSMC was able to recover sensitive technical documents that had allegedly been copied without authorization.

The case highlights ongoing concerns in Taiwan about protecting its semiconductor technology from being illicitly transferred to China.
