semiconductor supply chain

Semiconductor supply chain management coordinates wafer capacity, packaging, test, logistics, and customer commitments so chip demand can become shipped product. **Foundry allocation is where strategy becomes operational.** During shortages, the question is not only who wants wafers; it is who has qualified designs, credible forecasts, signed agreements, substrates, package capacity, and enough business importance to receive priority. | Allocation input | Why it matters | Risk if weak | |---|---|---| | Forecast quality | Lets the foundry reserve capacity with confidence | Lost priority or excess inventory | | Node and package readiness | Proves the design can consume wafers | Idle allocation or delayed ramp | | Customer tier | Reflects volume, relationship, and strategic value | Lower queue position | | Supply-chain completeness | Ensures wafers can become finished goods | Bottleneck moves to packaging or test | **Good management treats wafers as one part of a longer system.** A resilient plan aligns foundry slots, OSAT capacity, substrates, memory, firmware readiness, and end-customer demand before the first production wafer starts.
