Abstract:
1. A method of forming a semiconductor device, comprising: providing a substrate having a first surface and a second, opposing surface; forming at least one recess having an opening at the first surface of the substrate and extending thereinto toward the second, opposing surface of the substrate; positioning a plurality of preformed nanotubes generally within the at least one recess; positioning a volume of supporting material within the at least one recess to surround the plurality of preformed nanotubes and fill spaces between preformed nanotubes of the plurality of preformed nanotubes; and removing the plurality of preformed nanotubes, the volume of supporting material, and a portion of the substrate located around a periphery of the volume of supporting material from a remainder of the substrate.
