Intel Foundry’s Latest Milestone Is the World’s Thinnest GaN Chiplet, Measuring Just 19μm

Intel Foundry unveiled the world’s thinnest GaN chiplet, just 19 micrometers thick, built on 300 mm GaN-on-silicon wafers.

The design pairs GaN transistors with on-die digital control circuits, cutting the need for separate companion chiplets.

Reliability testing suggests the platform is ready for real-world deployment.

The milestone could enable smaller, faster, and more energy-efficient power electronics for data centers, servers, and 5G/6G networks.
