GPS ENGINEERING

RGB addressed at the semiconductor architecture—not assembled afterward.

Today’s RGB MicroLED systems typically depend on separately manufactured color devices, mass transfer, color conversion or other assembly pathways. The Hybrid Crystal architecture is intended to bring the semiconductor material systems associated with red, green and blue emission together on a unified crystalline platform.

A rhombohedral SiGe (111) integration layer creates a pathway for combining III–V and III–nitride semiconductor families. The platform remains in development while GPS organizes the technical data, scientific team, fabrication partners and capital required to create and validate the first Prime Wafer.

CAPABILITIES

III–V Materials

A material pathway associated with red emission within the proposed double-sided Hybrid Crystal architecture.

III–Nitride Materials

A material family associated with blue and green emission within a monolithic RGB platform.

SiGe (111) Integration

The crystalline integration layer connecting dissimilar semiconductor material families on the platform.

Prime Wafer Program

The staged effort to define, fabricate, characterize and validate the first production-oriented Hybrid Crystal wafer.

WHY GPS

A new architecture for light—and a foundation for American capability.

GPS intends the Prime Wafer to support advanced displays and broader photonic systems while helping connect domestic foundries, research institutions, national laboratories, industry and HBCU talent.
