  • Method of making mosaic array of thin semiconductor material of large substrates
    Patent number: 6562127
    Abstract: A method for making an array of thin single-crystal substrates on a handle substrate comprising the steps: attaching a plurality of single-crystal substrates to a face of a support wafer; polishing said plurality of attached single-crystal substrates so that said single-crystal substrates surfaces are coplanar on said support surface and to a selected surface roughness; implanting a hydrogen to a selected depth into said attached single-crystal substrates; bonding said polished and hydrogen implanted attached single-crystal substrates to a first handle substrate; and splitting said polished and hydrogen implanted attached single-crystal substrates at said selected depth thereby forming an array of thin single-crystal substrates on said first handle substrate and a support wafer having a remaining portion of said attached single-crystal substrates.
