Reports have emerged that a former Senior Vice President at TSMC, Wei-Jen Lo, has joined competitor Intel after retiring in July, raising concerns about a potential leak of sensitive information. Allegations suggest Lo may have taken confidential materials related to TSMC’s next-generation sub-2nm processes, including 2nm, A16, and A14 nodes. There are conflicting accounts regarding the scope of the materials, with some sources suggesting they could be personal handwritten notes rather than official company documents. TSMC is reportedly investigating the situation to determine if any proprietary information was compromised. The news follows a separate data leak case involving TSMC engineers in August, heightening security concerns for the chipmaker.
