Nvidia, Intel, and AMD Prepay Over NT$100 Billion to Secure Advanced IC Substrate Capacity in Taiwan
nashnova research
Nvidia, Intel, and AMD have collectively prepaid over NT$100 billion (≈US$5 billion) to Taiwan's IC substrate makers, securing long-term capacity for advanced AI chip packaging. The AI supply-chain race has moved upstream — from chips themselves to the materials beneath them.
How much is each company putting down?
Intel CEO Lip-Bu Tan said publicly that multiple clients have proactively prepaid deposits to help lock in substrate capacity. Analysts estimate Intel's long-term prepurchase at roughly US$3 billion — about 60% of the three-company total.
AMD previously announced a US$10 billion investment in Taiwan; the industry reads roughly US$1 billion of that as substrate-related.
Nvidia's investment in Taiwan substrate makers is also around US$1 billion, with room for further increases.
This means → Intel is committing the most, reflecting the heaviest catch-up pressure it faces in advanced packaging.
Why have IC substrates suddenly become the bottleneck?
IC substrates — the intermediary component connecting a chip to its circuit board, essentially the "bridge" between processor and motherboard — are in tight supply, directly constraining how fast the entire AI supply chain can ship.
AI chips keep growing larger with more packaging layers. Their substrate requirements for area and precision far exceed those of conventional chips.
In plain terms = the chip can be finished, but without an advanced substrate it cannot be mounted or shipped. Whoever secures substrate capacity first delivers AI chips first.
How are Taiwan's top three substrate makers responding?
Unimicron (欣興), Kinsus (景碩), and Nan Ya PCB (南電) have announced a combined NT$161.2 billion in new factory investment this year — an all-time high.
Unimicron raised full-year capex to NT$53.7 billion, added NT$17.6 billion in long-lead equipment orders, and acquired a Hukou plant for roughly NT$10.08 billion to expand capacity.
Kinsus is pivoting from traditional PCBs to advanced substrates, with total expansion budgets exceeding NT$40 billion. In 2026, NT$6 billion is earmarked specifically for ABF substrates — a high-end substrate material used in high-performance chips.
Nan Ya PCB committed the largest single project: NT$46.8 billion for a smart factory focused on large-format, high-layer-count advanced substrates.
What does the "prepay-to-lock-capacity" model tell us?
Tech companies are putting up large deposits to bind capacity in advance rather than wait for spot supply. This reflects a shift: supply-chain security has been elevated to the level of proactively paying to lock resources.
For substrate makers, customer prepayments provide demand visibility and underwrite the confidence behind massive capital spending.
This means → whether this binding model can keep delivering through the AI capex cycle is the core test for Taiwan substrate makers' long-term profitability.
