semiconductor supply chain

Semiconductor supply chain resilience is the ability to keep designing, fabricating, packaging, testing, and shipping chips when one part of the ecosystem is stressed. **The weak point is often a dependency no one modeled.** A team may secure wafers but miss advanced packaging capacity, substrates, HBM supply, probe cards, qualified second sources, export-control exposure, or firmware readiness. Resilience means mapping the whole path from design database to finished product. | Dependency | Resilience tactic | What it protects | |---|---|---| | Wafer foundry | Dual-node strategy, long-term allocation, mature-node fallback | Manufacturing continuity | | OSAT and package | Alternate package options, substrate planning, test capacity reservation | Ramp and delivery schedule | | EDA and IP | Version control, license planning, second-source IP where possible | Tape-out readiness | | Geography and policy | Export-control review, regional diversification, trusted suppliers | Market access and compliance | **Resilience has a cost, but shortages have a larger one.** The right plan spends selectively on optionality where a single constrained supplier could stop revenue, safety, or national-security-critical deployment.
