TSMC files lawsuit against former executive on security concerns

TSMC alleges Wei-Jen Lo breached contract and trade secrets laws after joining Intel, prompting government investigation into potential technology infringement and national security risks.

  • On Nov. 25, Taiwan Semiconductor Manufacturing Co filed a lawsuit in Taiwan's Intellectual Property and Commercial Court against former Senior Vice President Wei-Jen Lo, alleging trade secret theft and contract breaches tied to leaks to Intel.
  • Following Reuters and local reports, Taiwan's High Prosecutors Office opened a probe while Taiwan's economy ministry will assess possible infringement or National Security Act violations and monitor industry impact.
  • During a 21-year TSMC career, Lo helped drive mass production of 5-nanometre, 3-nm and 2-nm chips and retired on July 27, this year, despite his corporate strategy role.
  • TSMC's shares fell over 3% on the news, the U.S. firm's stock dropped 1.5%, prosecutors have yet to file criminal charges, and compensation is sought by TSMC.
  • TSMC alleged `There is a high probability that Lo uses, leaks, discloses or transfers TSMC's trade secrets and confidential information to Intel, thus making legal actions necessary`, while Intel CEO Lip-Bu Tan said his `company respects intellectual property rights` and Intel and Lo did not immediately respond.
