Abstract

Methods and apparatus for producing a semiconductor on glass (SiOG) structure include: subjecting an implantation surface of a donor semiconductor wafer to an ion implantation process to create an exfoliation layer in the donor semiconductor wafer; bonding the implantation surface of the exfoliation layer to a glass substrate using electrolysis; separating the exfoliation layer from the donor semiconductor wafer, thereby exposing at least one cleaved surface; and subjecting the at least one cleaved surface to a wet etching process.
