Writes Second Order by TKN — a plain-English map of AI infrastructure and semiconductors for non-specialist investors. Focus: who gets paid, where money sticks, and which step is stuck. Not investment advice.
What Taiwan does in the AI chain Taiwan sits at two scarce steps: leading-edge chipmaking and advanced packaging. Most of the AI accelerators that fill hyperscaler and neocloud racks are printed on TSMC wafers, then joined to high-bandwidth memory in CoWoS-class packages before they can ship. Server
US
September 2026 in one line: US AI infra still waits on power-ready halls — transformer lead times above 160 weeks, ERCOT’s >438 GW large-load queue, and neocloud power that is contracted faster than it is energised.
China
September 2026 in one line: MIIT wants 9,800 EFLOPS by 2030, Ascend cards just got much more expensive, and advanced HBM access is still the stuck step in China’s domestic AI stack.
Korea
September 2026 in one line: SK hynix's operating margin hit 76%, Korea's chip exports set another record, and HBM is still allocated to a short customer list. Who gets paid, and what dates change the read.
Taiwan
August 2026 in one line: TSMC sold NT$514.8bn, Taiwan shipped a record US$82.4bn, and packaging is still the step that sets the pace. Our Q3 math and the dates that matter.
Taiwan
Taiwan owns the AI finish line. Why a CoWoS capacity number means nothing without its variant, and what would show the packaging gate finally loosening.
US
A contracted backlog is not revenue. How neocloud contracts convert to cash, what the financing structure does to the risk, and what would break the model.
Korea
Korea holds the largest share of AI-class HBM output. How the allocation cycle turns into cash, and the four disclosures that tell you whether it is still tight.
Explained
Behind-the-meter power is on-site electricity on the customer's side of the utility meter. Leased megawatts do not pay until the hall is energised — and the queue is why that gap exists.
Explained
Advanced packaging still needs substrates and ABF film. The quiet neighbour gate — and how inventory builds when materials lag.
Explained
Process tools set HBM bit growth months before stacks ship. The equipment gate, the install-to-output clock, and where cash sits on the supply curve.
Explained
AI chips finish when foundry, packaging, HBM, substrates, and test all match. The wider finish line beyond one packaging brand name.
