How Semiconductor Supply Chains Work

Semiconductor supply chains connect chip design, fabs, lithography tools, packaging, export controls, Taiwan risk, and U.S. industrial policy.

1. Frame 1Chip demand turns U.S. buyers, overseas fabs, scarce tools, and CHIPS funding into one security-risk chain map.
2. Frame 2Design files move through a foundry gate, where specialized equipment and materials build wafer layers.
3. Frame 3Packaging and test form the bottleneck sequence: cut dies become usable processors, memory, or sensors for customers.
4. Frame 4A CHIPS funding ledger shows Commerce backing U.S. manufacturing, research, development, and worker pipelines as capacity bets.
5. Frame 5The export-control gate limits sensitive technology transfers when national security or foreign-policy risks rise.
6. Frame 6Watch the map: CHIPS awards, fab delays, packaging capacity, export-rule updates, and Taiwan disruptions show where the chain strains.
