Abstract

A method and structure for a semiconductor device, the device including a handle wafer, a diamond layer formed directly on a front side of the handle wafer, and a thick oxide layer formed directly on a back side of the handle wafer, the oxide layer of a thickness to counteract tensile stresses of the diamond layer. Nitride layers are formed on outer surfaces of the diamond layer and thick oxide layer and a polysilicon is formed on outer surfaces of the nitride layers. A device wafer is bonded to the handle wafer to form the semiconductor device.
