Claim Text:
1. A method of forming nanowire structures on a substrate comprising: etching a multi-material layer on a substrate, wherein the multi-material layer includes repeating pairs of a first layer and a second layer, the substrate further comprising a patterned hardmask layer disposed on the multi-material layer, wherein etching the multi-material layer exposes sidewalls of the first and the second layer of the multi-material layer through openings defined by the patterned hardmask layer, the multi-material layer having a first end coupled to a first side surface of a source anchor and a second end coupled to a second side surface of a drain anchor, the first and the second side surfaces of the source and the drain anchors longitudinally formed along two sides of the substrate respectively and circumscribing the substrate from the two sides; and laterally and selectively etching the second layer from the substrate.
