EntreMetrix Corporation (OTCBB: ERMX)
EntreMetrix has announced one of their first portfolio companies will be Advanced Nitride Devices, Inc., a raw manufacturer of Gallium Nitride (GaN). Gallium nitride is probably the most important semiconductor material since silicon.
Group4 Labs is now offering what it says is the world’s first 2-inch gallium nitride (GaN)-on-diamond semiconductor wafer. This creates another need for gallium nitride.
The wafer is the second in the company’s Xero Wafer family which offers a single GaN layer atomically attached to a synthetic diamond substrate, permitting “unprecedented” high temperature resilience. That makes it ideal for high-power, high-frequency electronic solid-state white lighting, military and photonics applications, according to Group4.
The Menlo Park, Calif.-based privately-held company says that its technology enables the GaN layer to be atomically attached to a freestanding, proprietary, polycrystalline chemical-vapor-deposited (CVD) diamond substrate (25-microns thick).
The GaN exposed is an atomically-smooth surface finish that is epi-ready for further epitaxial deposition. The device is commercially available as a freestanding 2-inch wafer or optionally on a disposable, silicon substrate to permit easy handling during wafer processing.
Group4 Labs’ proprietary GaN-on-Diamond technology addresses the classic heat problem plaguing the high power and high-speed transistor industry: excessive heat build-up inside the chip’s engine that ultimately leads to device failure, the company said in a statement. The new material system offer a unique solution by extricating heat from the chip’s core almost at the instant that it is generated. This is due to the nanometer proximity of the chip’s active region to diamond, which Group4 says is a nearly perfect thermal conductor.
EntreMetrix, Inc. has great raw material in developing Business Development Corporation status to aid its eligible portfolio companies with early stage capital, strategic guidance and operation support. Advanced Nitride Devices, Inc., which is a raw manufacturer of Gallium Nitride (GaN) is delivering semiconductor material that is already in demand.
