The Quarterly Pricing Data That Explains Why TSMC Dominates the Semiconductor Industry - Dr. Robert Castellano's Semiconductor Deep Dive Newsletter

This article analyzes TSMC's quarterly wafer pricing data to explain why the company dominates the semiconductor industry. Traditionally, as process technologies matured, manufacturing costs decreased... Read original →

TSMC has evolved from a foundry into the pricing anchor of the AI era. Historically, wafer costs declined as nodes matured, but at 3nm and below, escalating EUV layers and yield challenges invert that curve. AI chipmakers like NVIDIA and Apple now prioritize performance over price, triggering a tech stack ripple: ASML shifts focus to high-NA EUV, while system vendors redesign architectures to justify costly wafers. Geopolitical hedging—U.S., Japan, and EU fabs—adds 15%+ to operational costs, undermining non-Taiwan, China economics. Samsung and Intel may double down on captive strategies, yet lack volume-proven reliability. Over the next 12–24 months, AI training chips will consume ~80% of advanced capacity, cementing TSMC’s pricing hegemony and ushering in a 'performance premium' regime that sidelines smaller fabless players from cutting-edge nodes.
