Method for manufacturing nitride semiconductor crystal layer

Abstract

According to one embodiment, a method is disclosed for manufacturing a nitride semiconductor crystal layer. The method can include forming the nitride semiconductor crystal layer having a first thickness on a silicon crystal layer. The silicon crystal layer is provided on a base body. The silicon crystal layer has a second thickness before the forming the nitride semiconductor crystal layer. The second thickness is thinner than the first thickness. The forming the nitride semiconductor crystal layer includes making at least a portion of the silicon crystal layer incorporated into the nitride semiconductor crystal layer to reduce a thickness of the silicon crystal layer from the second thickness.
