Abstract
Systems and methods for and products of a semiconductor-on-insulator (SOI) structure including subjecting at least one unfinished surface to a laser annealing process. Production of the SOI structure further may 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 an insulator substrate; 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 the laser annealing process.
Claims16
A method of forming a semiconductor-on-insulator structure, comprising:
- subjecting an implantation surface of a crystalline donor semiconductor wafer to an ion implantation process to create an exfoliation layer of the donor semiconductor wafer;
- bonding the implantation surface of the exfoliation layer to an insulator substrate;
- separating the exfoliation layer from the donor semiconductor wafer, thereby exposing at least one cleaved surface;
- and
- subjecting the cleaved surface to a radiation annealing process.
