Tokyo Electron Taiwan Fined NT$150M in TSMC 2nm Trade Secret Case — Global Semiconductor IP Enforcement Scrutiny Intensifies

Follow-up reporting on April 28, 2026 detailed the full scope of Taiwan's landmark TSMC trade secrets verdict from April 27, focusing on the Tokyo Electron Taiwan subsidiary's NT$150 million corporate fine (approximately USD $4.78 million) — one of the largest fines ever imposed on a Japanese company in Taiwan. The case centered on misappropriation of TSMC's 2nm-generation process technology: former engineer Chen Li-ming, sentenced to 10 years in prison, passed proprietary manufacturing process data to Tokyo Electron to help the equipment supplier gain competitive advantage in developing tools for TSMC's cutting-edge fabs. Additional reporting examined the broader implications: Taiwan's strengthened enforcement posture reflects island-wide recognition that semiconductor IP protection is now a national security imperative, not merely a commercial matter. TSMC's 2nm process (N2 node) is critical to global AI infrastructure — major customers including Apple, NVIDIA, AMD, and Qualcomm depend on it for next-generation chip production. The 2nm node is not commercially available from any other foundry globally. The verdict drew comparisons to the US CHIPS Act's 'guardrails' provisions restricting chip technology transfer, and was seen as Taiwan's analogous domestic enforcement response to US export control policy. Tokyo Electron is among the world's top semiconductor equipment suppliers and has a complex business relationship with TSMC that must now proceed under intensified IP oversight frameworks.
