Abstract

Methods of forming a microelectronic structure are described. Embodiments of those methods include forming a plurality of openings in a portion of a first side of a substrate, bonding a first silicon layer of a silicon on insulator wafer to the first side of the substrate, wherein the silicon on insulator wafer comprises the first silicon layer disposed on an insulator layer disposed on a second silicon layer, forming a plurality of support structures by removing a portion of a second side of the substrate, removing the second silicon layer and removing the insulator layer.
