WBG policy research

Building a semiconductor factory does not automatically create usable supply. Chips still need packaging, application testing, customer acceptance, dependable supply access, and long-term support. This research asks how policy can connect investment with technology that people can actually use.

Example route: silicon carbide for electric-vehicle traction.

1. 01MaterialsPrepare suitable material and substrates
2. 02EpitaxyBuild the required semiconductor layers
3. 03Device fabricationTurn prepared wafers into devices
4. 04Packaging & testConnect, protect, cool, and test devices
5. 05System integrationAssess the device in its application
6. 06Operation & supportKeep accepted supply available and supportable

• Assess usable supplyA framework that looks beyond factory capacity to qualification, access, and support.
• Target policy supportA way to examine where packaging, testing, customer acceptance, or supply continuity needs attention.
• Keep applications separateAssess each technology route against its intended use, rather than combining unlike demand totals.
