What if it fails?

Step one · 1How 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 →Check this number with Ask bottleneck hit directly

• Neon, excimer laser grade → Leading-edge foundry capacity

  An input to Leading-edge foundry capacity is disrupted. Whether it stops depends on inventory and substitution the corpus does not record.

  Evidence for each step

  • Leading-edge foundry capacity needs Neon, excimer laser gradeTheir highly pure inert neon gas is needed as a buffer for lasers used during the chip fabrication process.Secondary source · Chip fabrication in general, not the leading edge only.

• Neon, excimer laser grade → Leading-edge foundry capacity → Advanced packaging capacity

  An input to Advanced packaging capacity is disrupted. Whether it stops depends on inventory and substitution the corpus does not record.

Step three · 23How 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 →Check this number with Ask companies exposed, 19How 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 →Check this number with Ask 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.
