American Cree and STMicroelectronics have extended their SiC 150mm wafer supply deal which is now worth more than $800 million.

"This latest expansion to our long-term wafer supply agreement with Cree will continue to contribute to the flexibility of our global silicon carbide substrate supply," says STMicroelectronics CEO Jean-Marc Chery.

"Our long-term wafer supply agreements with device manufacturers now total more than $1.3 billion and help support our efforts to drive the industry transition from silicon to silicon carbide," says Cree CEO Gregg Lowe.
