Group4 Releases 50nm Diamond Wafer
 

Group4 Labs is now offering what it says is the world’s first 2-inch gallium nitride (GaN)-on-diamond semiconductor wafer.

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.
