Abstract:
1. A method for forming a single-crystal silicon layer on a transparent substrate, comprising: providing a transparent substrate having an amorphous silicon layer formed thereon and a silicon wafer having a hydrogen ion layer formed therein; inverting and laminating the silicon wafer onto the amorphous silicon layer so that a layer of single-crystal silicon layer is between the hydrogen ion layer and the amorphous silicon layer; and subjecting the laminated silicon wafer and the amorphous silicon layer to infrared light to cause chemical bonding of the single-crystal silicon layer and the amorphous silicon layer and inducing a hydro-cracking reaction in-situ thereby separating the silicon wafer and the transparent substrate at the hydrogen ion layer, and leaving the single-crystal silicon layer on the transparent substrate.
