Sapphire Wafers

Adamant-Namiki employs a unique crystal growth method, EFG (Edge-defined Film-Fed Growth Method), that eliminates the need for additional processing by growing single crystal sapphire in a sheet-shape, thereby enabling the sapphire wafer to meet QCD (quality, cost, and delivery) requirements. In addition to epitaxial growth for LED/LD applications, and carrier wafers for semiconductor devices requiring larger diameter and perfect surface finishing, we have been supplying sapphire products to a wide range of industries (e.g., for windows requiring a very flat shape) , satisfying customer's' specs (TTV, BOW, cleanliness). We are also able to meet requests for specially shaped products, such as stepped structure or adding through holes.
