Definition
The AI chip supply chain is the worldwide sequence of specialized companies that turns a chip design into a finished AI processor, spanning design, equipment, fabrication, memory, and packaging.
At a glance
- No one company makes an AI chip alone; the work splits across firms in the US, Netherlands, Taiwan, and South Korea.
- Three anchors: Nvidia designs, ASML alone makes the machines to print them, TSMC manufactures.
- Memory (HBM) and packaging (CoWoS) are now the tightest chokepoints.
- Capacity is sold out years ahead, so any one shortage can throttle the whole AI buildout.
How it works
Think of a relay where each runner is a different company. Designers (Nvidia) draw the blueprint. ASML of the Netherlands alone makes the EUV machines that etch the finest circuits[1]. Taiwan’s TSMC fabricates the chip. Memory makers supply HBM, then advanced packaging like CoWoS bonds chip and memory into one finished part[2].
Why it is fragile
Each step has one or two suppliers, so the chain is only as strong as its scarcest link. ASML’s EUV near-monopoly caps how fast compute can grow[3]. CoWoS packaging is booked into 2026, with Nvidia reserving over half[4], and HBM stays constrained through 2027[5]. A shock to any one supplier, especially Taiwan, ripples everywhere, keeping AI compute scarce and expensive.
Bottom line
An AI chip is a relay between a handful of irreplaceable firms, and memory and packaging are the legs most likely to stall.
