Abstract:
1. A method for forming a thin film material for at least one of a solar device, a semiconductor device, or an electronic device during an epitaxial lift off process, comprising: forming a contiguous epitaxial material over a sacrificial layer on a substrate; adhering a support handle onto the contiguous epitaxial material, wherein the support handle comprises a contiguous stiff support layer adhered to the contiguous epitaxial material, a soft support layer adhered to the contiguous stiff support layer, and a handle plate adhered to the soft support layer; removing the sacrificial layer during an etching process; and peeling the contiguous epitaxial material from the substrate while forming an etch crevice therebetween while maintaining compression in the contiguous epitaxial material during the etching process.
