Abstract

A method for fabricating a silicon-on-sapphire wafer for processing by silicon-wafer-processing equipment. A layer is deposited on a backside of a silicon-on-sapphire wafer, the layer having optical and electrical properties of silicon, wherein the silicon-on-sapphire wafer may be sensed by a sensor designed to sense a presence of a silicon wafer.
