Abstract

CoWoS / Chip Cost Calculator & Capacity data. Fetched by the auto-model research pass; the figures below are cited from this source in the model's flow, idiot-index, energetic-index, and market tabs.

Key facts

• CoWoS adds ~$500-1,500+ per package depending on interposer size, HBM stack count, substrate complexity
• CoWoS demand ~370k wafers 2024, ~670k 2025, ~1.0M 2026

Reviewer note

Real source gathered during the extend-silicon-stack research pass (2026-06-21). Figures attributed to it in the model link back here.
