What will computer chips look like in 2045?

1h 9min

This episode explores how AI-driven demand is straining semiconductor production, with Intel leaders detailing the bottlenecks from tool supply (ASML's EUV machines) to transistor architecture (Gate-All-Around, CFETs), and how innovations like backside power and hybrid bonding are shaping chips through 2045. The discussion highlights Intel's lessons from past delays (10nm), the need for pre-ordering capital equipment to capture AI growth, and the shift toward 3D stacking and tighter interconnects to overcome heat and scaling limits.

✨ Key Takeaways

1

AI demand is 40-50% above Intel's peak capacity, and the entire semiconductor supply chain is bottlenecked by tool suppliers like ASML, which produces fewer than 100 EUV machines per year.
2

Transistor design lags innovation by decades: Gate-All-Around was conceived in the 1980s but only entered production in 2022 due to materials and integration challenges.
3

Backside power is a key enabler for high-NA EUV—by moving power lines to the wafer's back, Intel reduces routing congestion and makes single-pass lithography viable.
4

Hybrid bonding pitches are shrinking from 25µm to sub-0.5µm, allowing chip-to-chip connections that rival on-chip wiring and could reduce total system power.
5

Foundry economics are brutally fixed-cost heavy (80%), with only three advanced players left—Intel must aggressively pre-order tools to capture AI demand by 2030.

"We're seeing all equipment seeing tremendous supply shortage…once you lock into a process flow, you need a specific tool. You can't just go get a different one. — Pushkarande (CTO)"
"We use a tiered hotbox system…the highest grade, hotbox one, races through the factory like a carpool lane. But it drags the whole factory. — Kevin Fisher"
"The demand is so high, a few billion in capex can produce chips that generate $100 billion in AI revenue. So yeah, maybe we should be buying more tools. — Dwarkesh"
