Patent ID: 7508573

Claim:
An optical switch structure, comprising: a first contact electrode; a substrate, said substrate being deposed on a surface of said first contact electrode; a proton-implanted region, said proton-implanted region being deposed on a surface of said substrate, said proton-implanted region being processed with an implantation with an energy between 1 KeV and 1 MeV, said proton-implanted region having an implantation dose between 1×10 12 /cm 2 and 1×10 16 /cm 2 , said proton-implanted region being obtained under an annealing ambiance, said annealing ambiance comprising an inert gas and an annealing temperature, said inert gas having at least 1 ppm of oxygen molecules, said annealing temperature being located between 350° C. and 600° C.; and a second contact electrode, said second contact electrode being deposed on said proton-implanted region, said second contact electrode being located at center of said proton-implanted region.
