Abstract:
1. A method of fabricating a structure, comprising: providing a substrate having a top surface; forming an island on said top surface of said substrate, a top surface of said island parallel to said top surface of said substrate, a sidewall of said island extending between said top surface of said island and said top surface of said substrate; forming a spacer on said sidewall of said island, said spacer extending between said top surface of said island and said top surface of said substrate; forming a plurality of carbon nanotubes on said spacer; after forming said plurality of carbon nanotubes, forming a conformal layer on top of said carbon nanotubes; and performing an ion implantation, said ion implantation penetrating into said island and blocked from penetrating into said substrate in regions of said substrate masked by said island, said spacer and said carbon nanotubes.
