Unimicron Technology Corp. — AI supply-chain exposure
The model reads Unimicron Technology Corp. primarily as a supplier in Chips. Its strongest structural lever is GPU (system bottleneck #2), which it produces or supplies — genuine pricing power. Its largest modeled sensitivity is a shock at Silicon wafer supply (constraint β 9).

Unimicron is one of two leading makers of advanced ABF IC substrates — the high-density, interposer-like layer that carries an SoC or GPU package out to the board. Analysts describe the top tier as a quiet duopoly shared with Ibiden. Its substrates are a constrained input for AI accelerators and ASIC packages built on CoWoS and similar advanced packaging, which positions it as a linchpin supplier feeding the compute stack.
Its structural hook mirrors Ibiden's: the most advanced substrate is slow and expensive to build, so capacity, not design, sets the ceiling on how many packages can be finished. When AI demand runs hot, this layer is one of the first to tighten. Unimicron carries more conventional PCB business — phones, autos, networking — which cushions and dilutes the AI signal, so the model places it just behind the purest substrate names while keeping it near the centre of the chain.
