TSMC/CoWoS advanced packaging

TSMC agreed to buy a closed Innolux flat-panel display plant in Tainan for NT$17.14 billion (approximately US$530 million) to add advanced packaging capacity. The acquisition came as TSMC aimed to more than double CoWoS capacity amid AI chip supply constraints.

• TSMC purchased closed Innolux facility in Tainan for NT$17.14B ($530M USD), gaining ready-built production space.
• Acquisition supplies ready-built facilities to rapidly expand CoWoS advanced packaging, a critical bottleneck for AI accelerator supply.
• Expansion targets more than doubling CoWoS capacity to address severe AI chip demand exceeding packaging supply.
