Scenarios
What if it fails?
Pick a scenario on the record, or build your own from a company (private ones included), a bottleneck or a country. You get what it hits, what lies downstream, which listed companies are exposed, and what the record says about recovery — one recorded step at a time (rule).
Taiwan is cut off
Why this is a live question: No accepted event; the record is the concentration on leading-edge foundry capacity

Step one · How this is computedDirect hits: bottlenecks where the failed node is a maker, a part supplier or the location. Makers wholly inside it are lost; makers also operating elsewhere are partly affected; the rest remain. Downstream: every bottleneck that needs a hit one, transitively, through recorded rows. Exposed: holders of hit and downstream bottlenecks and companies a filing says need or sell into them.Method →Code → bottlenecks hit directly
| Bottleneck | Result | Makers lost | Partly in it | Makers remaining | Parts lost |
|---|---|---|---|---|---|
| Advanced packaging capacity | No recorded maker left | TSMC Advanced Packaging | none | none | none |
| Leading-edge foundry capacity | Other recorded makers remain | TSMC | none | How this is computedDirect hits: bottlenecks where the failed node is a maker, a part supplier or the location.

Step two · How this is computedDirect hits: bottlenecks where the failed node is a maker, a part supplier or the location. Makers wholly inside it are lost; makers also operating elsewhere are partly affected; the rest remain. Downstream: every bottleneck that needs a hit one, transitively, through recorded rows.

300 mm prime silicon wafers → High-bandwidth memory stacking yield
An input to High-bandwidth memory stacking yield is disrupted. Whether it stops depends on inventory and substitution the corpus does not record.
Evidence for each step
- High-bandwidth memory stacking yield needs 300 mm prime silicon wafers
300 mm Memory chip / DRAM / Flash(NAND)
Primary source · DRAM in general; HBM is stacked DRAM.
- High-bandwidth memory stacking yield needs 300 mm prime silicon wafers
Step three · How this is computedDirect hits: bottlenecks where the failed node is a maker, a part supplier or the location. Makers wholly inside it are lost; makers also operating elsewhere are partly affected; the rest remain. Downstream: every bottleneck that needs a hit one, transitively, through recorded rows. Exposed: holders of hit and downstream bottlenecks and companies a filing says need or sell into them.Method →Code → companies exposed, How this is computedOrganisations recorded on a bottleneck (maker, capacity holder or part supplier) whose shares, or a parent’s, trade on an exchange found in the SEC ticker file or OpenFIGI.Method →Code → with a listing
Exposure is a recorded relation, not a size, and not a direction: a remaining maker may gain as much as a dependent loses.

Step four · what the record says about recovery
No recovery date is computed: the corpus holds no measured lead-time series. What it holds is shown with its basis.
- Advanced packaging capacity
- Lead-time test
- Estimate by Substrata, open to challenge, 2026-09-15: Accelerator output is set by CoWoS-class capacity, allocated ahead and still short of demand.

- Estimate by Substrata, open to challenge, 2026-09-15: The corpus tracks five producers of prime 300 mm wafers. Their product pages establish production, not global coverage, market share or customer contracts. Qualification constraints and demand from new fabs remain analyst hypotheses to investigate.Estimate, not a measurementThe corpus tracks five producers of prime 300 mm wafers.
