Taiwan Investigates Former TSMC Executive's Move to Intel

Taiwan has initiated an inquiry into a retired senior executive from TSMC who allegedly took confidential semiconductor technology to Intel after joining the U.S. chipmaker earlier this year. This case has garnered significant attention within the global semiconductor industry, where the race for advanced manufacturing capabilities is intensifying.

Reports have identified the individual as Wei-Jen Lo, pivotal in TSMC's innovations in 5-nanometre, 3-nanometre, and 2-nanometre processes. After more than two decades at TSMC, he transitioned to Intel in October, with claims suggesting he may have transferred sensitive data prior to his exit, leading to the current investigation.

Taiwan's High Prosecutors Office has acknowledged these reports and opened a preliminary investigation, although no charges or formal complaints are on record. Officials aim to determine whether unauthorized technology transfer occurred and whether national security regulations might be involved.

Economy Minister Kung Ming-hsin stressed on Wednesday that the government is taking this issue seriously, noting that semiconductor expertise is regarded as a vital strategic resource. He indicated that authorities would work closely with prosecutors to evaluate the adequacy of current controls on advanced technology protection.

TSMC has not commented on this matter. Similarly, Intel has not acknowledged Lo's appointment publicly. A source familiar with the situation revealed that Lo is currently involved with Intel and reports directly to CEO Lip-Bu Tan.

Lo's 21-year tenure at TSMC includes leading research and advanced technology development. He was at Intel for 18 years before joining TSMC in 2004, where he held various leadership roles, including director of technology development.

The government plans to closely monitor how this case might affect Taiwan's semiconductor ecosystem and its relationships with significant international partners. The investigation is still in its early stages, with authorities gathering relevant information.
