World-leading advanced substrate maker Soitec and compound materials leader Sumitomo Electric are launching pilot production of 4” and 6” GaN wafers for the LED and power markets. Soitec applies its Smart CutTM layer-transfer process to Sumitomo’s bulk GaN wafers to generate engineered wafers with the same thermal expansion (CTE) as standard GaN wafers but at lower costs.











Both bulk epi growth of GaN and smart-cut process are expensive technologies. So, what will be the cost of this advanced substrate ?
