Every AI accelerator headline is about the die. The actual ceiling on how many of them the world can build in 2026 sits one manufacturing step later, in a packaging process most coverage never names.
A larger single die should, in principle, be faster. It is also exponentially more likely to contain a fatal defect. This briefing works through the actual yield arithmetic behind the industry's shift to chiplets.
A finished wafer isn't a sellable product. Someone still has to cut it, package it, and test it — and the largest company doing that job, ASE Technology, holds nearly half the entire advanced-packaging market.
TSMC is building the wafer fab. Amkor is building the packaging plant next door — the piece that would let a chip go from raw silicon to finished, tested product without ever leaving the country.
Performance now moves on the assembly rather than the transistor. Once a die is cut into pieces, the interface between them becomes the design, and the cost of a bit is set largely by how far that bit has to travel.
Petaflops are the advertised number and almost never the binding one. An accelerator is a memory system with arithmetic attached, and every serious design decision of the last decade follows from that.
