Claim:
1. A method for fabricating a semiconductor device, comprising: providing a structure comprising a stressor layer stack on a first surface of a semiconductor substrate; forming an interfacial release layer on a second exposed surface of the semiconductor substrate; bonding the interfacial release layer to a rigid handle substrate using an epoxy adhesive; removing at least a portion of the stressor layer stack from the semiconductor substrate; processing the semiconductor substrate; forming a layer comprising a finger/bus metal and an anti-reflective coating on the semiconductor substrate; applying a sacrificial mask to the layer comprising the finger/bus metal and the anti-reflective coating; patterning the layer comprising the finger/bus metal and the anti-reflective coating; removing the sacrificial mask; and removing the semiconductor substrate from the interfacial release layer using a tape superstrate to impart flexibility to the semiconductor substrate.
