Patent ID: 8642453

Claim:
A method of forming a Schottky barrier diode comprising: forming a silicon island in an insulator, said silicon island having an exposed top surface, a first area, and a second area; forming an isolation structure on said exposed top surface above an interface between said first area and said second area, said isolation structure comprising only an isolation pad patterned from only a single layer of isolation material; doping said first area with one of a p-type dopant and an n-type dopant; and performing a metal silicide formation process such that a first metal silicide region contacts said first area and extends above said top surface and is positioned laterally immediately adjacent to a first side of said isolation pad and such that a second metal silicide region contacts said second area and extends above said top surface and is positioned laterally immediately adjacent to a second side of said isolation pad opposite said first side, said isolation structure separating said first metal silicide region from said second metal silicide region, and said second metal silicide region forming a Schottky barrier contact to said second area.
