Abstract
A method of forming a free-standing silicon film that includes providing a Si substrate, depositing a layered structure on the Si substrate, where the layered structure includes a Si device layer and a SiGe sacrificial layer, and removing the SiGe sacrificial layer with a spin etch process, where the Si device layer is released from the layered structure.
