Patent ID: 8323995

Claim:
A method of forming a diode, comprising: forming a metal silicide-containing structure, the metal silicide-containing structure having a surface that is silicon rich relative to other metal silicide of the structure; oxidizing said surface to form SiO 2 , and leaving some of the metal silicide not oxidized; the metal silicide that is not oxidized being at least part of a first electrode; depositing at least one metal-containing oxide across the SiO 2 ; forming a second electrode over said at least one metal-containing oxide; and wherein the first electrode, SiO 2 , at least one metal-containing oxide, and second electrode together form a construction that conducts current between the first and second electrodes when voltage of one polarity is applied to the construction, and that inhibits current flow between the first and second electrodes when voltage having a polarity opposite to said one polarity is applied to the construction.
