TrendForce said TSMC is focusing on CoPoS and has locked a 310×310 mm substrate size. It expects 2026 to be the key validation year for related equipment and materials vendors, 2027 for pilot production and H2 2028 for mass production. TSMC’s next-stage focus is expected to shift to glass substrates, with mass production likely after 2030.
