Japanese semiconductor firms are pivoting toward advanced packaging and alternative lithography as TSMC extends its scale advantage in artificial intelligence chips. TSMC’s 3nm and 2nm capacity is largely locked in. Advanced packaging now contributes a growing share of sales. The company is on track to see annual revenue exceed US$250 billion around 2029 or 2030. That widening gap has pushed Japanese companies to focus on panel-level packaging and nanoimprint technologies. Both emerged at SEMICON Japan 2025 as key levers to bypass manufacturing bottlenecks and secure a foothold in the fast-expanding AI accelerator supply chain.
