Patent ID: 6881623

Claim:
A method of forming a chalcogenide comprising device, comprising: forming a first conductive electrode material on a substrate; forming an amorphous chalcogenide comprising material to a first thickness over the first conductive electrode material, the chalcogenide material comprising A x B y , where “B” is selected from the group consisting of S, Se and Te and mixtures thereof, and where “A” comprises at least one element which is selected from Group 13, Group 14, Group 15, or Group 17 of the periodic table; forming a metal comprising layer to a second thickness over the chalcogenide comprising material, said second thickness being less than, but not within 10% of a transition thickness of said metal comprising layer, said transition thickness being a thickness of said metal layer which, when diffused into said chalcogenide comprising material, transforms said chalcogenide comprising material from an amorphous to a crystalline state; irradiating said metal comprising layer such that at least some of the metal is diffused into the chalcogenide material; and forming a second conductive electrode over the chalcogenide comprising material.
