An apparatus and a method for forming the apparatus include a semiconductor layer on an insulating substrate, where the substrate is a different material than the semiconductor layer, and has a coefficient of thermal expansion substantially equal to that of the semiconductor layer. The semiconductor layer can also be formed having a thickness such that it does not yield due to temperature-induced strain at device processing temperatures. A silicon layer bonded to a silicon oxycarbide glass substrate provides a silicon on insulator wafer in which circuitry for electronic devices is fabricated.
