Taiwan's investigation into alleged trade-secret leaks from TSMC has escalated, with prosecutors searching the homes of former Senior Vice President Lo Wen-jen and freezing his assets amid concerns he may have transferred 2nm-related IP to Intel.

Homes Searched, Devices Seized, Assets Frozen

Prosecutors said on November 28 that investigators executed search warrants at Lo's residences in Taipei and Hsinchu on November 27, seizing computers, USB drives, and related devices. A court also approved freezing Lo's stocks and real-estate assets.

Authorities said Lo is suspected of violating Taiwan's "Security Act," though no criminal charges have been filed.

TSMC filed a civil lawsuit earlier this week, claiming there is a "high likelihood" Lo misappropriated confidential information before leaving the company. Lo retired from TSMC in July after a 21-year career leading development of 5nm, 3nm, and 2nm technologies before rejoining Intel in October.

Intel Denies Allegations

Intel rejected TSMC's accusations in a statement on November 28, saying it has "no reason to believe the allegations against Mr. Lo have any merit."
The company added that it enforces strict rules prohibiting the use or transfer of third-party confidential information.

Intel called Lo a respected veteran whose return to the company reflects normal industry talent movement

Government Watching Closely

Economy Minister Kung Ming-hsin said the government is monitoring the case, noting that national-security issues could be involved if protected semiconductor IP was transferred.

Local media reports say investigators are examining whether Lo retained documents related to 2nm-class development or restricted A14/A16 data, though prosecutors have not confirmed details.

Broader Implications

The case comes as Intel races to catch up with TSMC in advanced manufacturing, including its upcoming Intel 18A node. The investigation is expected to test how effectively Taiwan's legal system and industry safeguards can prevent IP leakage in a sector where senior talent frequently moves between competitors.

TSMC and Lo have not issued further public comments.
