Overview
CoWoS (Chip-on-Wafer-on-Substrate) is TSMC's advanced packaging technology, introduced in 2016, that integrates high-performance processors with memory for AI computing systems. It has become the critical bottleneck for AI GPU production — TSMC's CoWoS capacity is sold out through 2026 despite scaling to 120,000-130,000 wafers per month.
