Abstract:
A method for fabricating a silicon structure on a transparent substrate comprising the steps of:providing a transparent substrate;depositing a thin film of silicon on said substrate;recrystallizing said thin film of silicon by a Solid Phase Epitaxy process;reducing said thin film of silicon in height through a selected number of oxidation and etching steps so that said height lies in the range of 1 to 100 nanometers;lithographically defining a width and length of said thin film of silicon deposited on said substrate, said width and length creating an area of said silicon that lies adjacent said transparent substrate, said lithographically defining including the steps of:placing a photoresist on said thin film of silicon;exposing said photoresist to affect a pattern on said photoresist;removing selected portions of said pattern on said photoresist where said silicon is desired to be removed;etching said silicon where said resist has been removed so that said width of said silicon lies in the range of 1 to 100 nanometers and so that said length of said silicon is as least as long as the greater of the height and width of said silicon structure.
