Patent ID: 7811906

Claim:
A method of forming a carbon-on-insulator structure comprising: providing an initial structure including an insulating surface layer on a base substrate; providing at least one layered metal/carbon (M/C) region on said insulating surface layer, said at least one layered M/C region including an upper patterned carbon layer and a lower patterned metal layer, and said at least one layered M/C region having edges bordered by exposed regions of the insulating surface layer; providing securing structures to secure some edges of said at least one layered M/C region to the base substrate, while leaving other edges of said at least one layered M/C region exposed and unsecured, wherein each securing structure comprises a securing material disposed over some portion of the at least one layered M/C region edge and some portions of both the least one layered M/C region and the insulating surface layer directly adjacent the at least one layered M/C region edge; selectively removing the patterned metal layer of the at least one layered M/C region by an etching process wherein etchants used have access to the patterned metal layer via the unsecured edges of the at least one layered M/C region; and allowing the patterned carbon layer to bond to the insulating surface layer after a desired amount of metal has been removed by the etching process.
