AI Chips’ New Secret Sauce Is Packaging
A facts-only brief, written by a local AI model from this article in The Wall Street Journal, October 13, 2026. It may contain mistakes, and it is not the article: the full story is at wsj.com.
The semiconductor industry is increasingly relying on advanced packaging techniques to improve chip performance, as traditional methods of shrinking transistors face diminishing returns and rising costs. This shift allows manufacturers to combine multiple silicon pieces, some produced with older, cheaper technology, into single units to enhance efficiency and yield. Nvidia’s market-leading AI chips depend on these packaging technologies developed by TSMC to integrate high-bandwidth memory with processing power, although packaging capacity has recently acted as a bottleneck for sales. TSMC has responded by converting existing factories into packaging facilities and expanding capacity over the past few years.
Background
- Applied Materials CEO Gary Dickerson stated in August that packaging-related revenue is expected to grow by more than 70% this year.
- Chipmakers like AMD and Intel moved toward advanced packaging before the AI boom to reduce reliance on expensive single-silicon manufacturing.
- Future packaging strategies are expected to involve stacking silicon pieces vertically rather than placing them side by side.
- TSMC, which reports quarterly results on Thursday, is bringing more packaging activities in-house, a sector historically characterized by lower margins.
