Patent ID: 7399681

Claim:
A method of forming a semiconductor on glass structure, comprising: establishing an exfoliation layer on a semiconductor wafer; contacting the exfoliation layer of the semiconductor wafer to a glass substrate; applying pressure, temperature and voltage to the semiconductor wafer and the glass substrate, without a vacuum atmosphere, such that a bond is established therebetween via electrolysis; and applying stress such that: (i) the exfoliation layer separates from the semiconductor wafer and remains bonded to the glass substrate; (ii) the exfoliation layer includes a layer of enhanced oxygen content; and (iii) the glass substrate includes a first substrate layer adjacent the layer of enhanced oxygen content and having a reduced positive ion concentration in which substantially no modifier positive ions are present, and a second substrate layer adjacent the first substrate layer and having an enhanced positive ion concentration of modifier positive ions, including at least one alkaline earth modifier ion.
