Soitec, Sumitomo team up to develop engineered GaN substrates

摘要

Soitec, a leading supplier of engineered substrates, and Sumitomo Electric Industries , a provider of compound semiconductor materials, have teamed up to develop engineered gallium nitride (GaN) substrates. This collaboration promises lower-cost GaN substrates that would be used in applications including high-brightness LEDs, as well as electric power devices designed for hybrid and full electric vehicles.rnThe partnership will draw on Sumitomo Electric's unique GaN wafer manufacturing technology and Soitec's Smart Cut layer transfer technology by which ultrathin GaN layers are transferred from a single GaN wafer to produce multiple, engineered GaN substrates. The engineered substrates retain the original, high crystalline quality of Sumitomo Electric's GaN wafer at a lower cost.
