Intel is pushing back against TSMC’s newly filed lawsuit involving former executive Dr. Wei-Jen Lo, with Intel CEO Lip-Bu Tan making it clear that the company stands behind the hire and rejects any suggestion of an improper transfer of confidential know-how.
In an internal message to employees, Tan said Intel sees “no merit” in the allegations tied to Lo and emphasized that Lo continues to have Intel’s full support. Tan also highlighted Lo’s long history with Intel, noting that he previously spent 18 years at the company helping develop wafer processing technology before moving to TSMC, where he continued working in a similar area.
The core of the dispute centers on TSMC’s concern that Lo had access to confidential information that could potentially help a competitor in the race for advanced semiconductor manufacturing. In its lawsuit, the Taiwanese chipmaking giant argues there is a risk that sensitive trade secrets could be exposed by the executive’s move. Intel’s response, however, is an unequivocal denial, with Tan stating the company has strict internal rules designed to prevent any use or transfer of third-party confidential information or intellectual property.
Tan’s memo is also notable because it is one of the clearest public acknowledgments from Intel leadership directly naming Lo in connection with the move, signaling that Intel is treating the transition as legitimate and moving forward despite the legal noise.
From a technology standpoint, Intel argues it is pursuing a process roadmap that differs in meaningful ways from TSMC’s approach. Intel’s advanced process efforts, including 18A and future nodes, include technologies such as PowerVia and RibbonFET. Intel is also positioning itself as an early adopter of High-NA EUV lithography, an area where TSMC has not yet made the same leap. Because the technical paths diverge, Intel’s stance implies that the fear of a direct “blueprint handoff” is misplaced.
If Intel gains anything from Lo’s experience, the more likely value may be strategic rather than technical—insight into foundry customer expectations, supply chain decision-making, and what major U.S. clients want when choosing a contract chip manufacturer. Still, Intel maintains that there is no intention, mechanism, or appetite for any transfer of protected technology.
With TSMC escalating the issue through formal legal action and Intel publicly drawing a firm line in response, the situation is shaping up to be a high-stakes fight between two of the world’s most important semiconductor players. How the case unfolds could have broader implications for executive hiring, trade secret protections, and competition in the advanced chip manufacturing race.
