Abstract

See full text

A wafer-scale multiple carbon nanotube transfer process is provided. According to one embodiment of the invention, plasma exposure processes are performed at various stages of the fabrication process of a carbon nanotube device or article to improve feasibility and yield for successive transfers of nanotubes. In one such carbon nanotube transfer process, a carrier material is partially etched by a plasma process before removing the carrier material through, for example, a wet etch. By applying the subject plasma exposure processes, fabrication of ultra-high-density nanotubes and ultra-high-density nanotube grids or fabrics is facilitated. The ultra-high-density nanotubes and ultra-high-density nanotube grids or fabrics fabricated utilizing embodiments of the invention can be used, for example, to make high-performance carbon nanotube field effect transistors (CNFETs) and low cost, highly-transparent, and low-resistivity electrodes for solar cell and flat panel display applications. Further, three-dimensional CNFETs can be provided by utilizing the subject plasma exposure processes.
