Patent ID: 8841196

Claim:
A method of forming a non-volatile memory device, comprising: providing a semiconductor substrate having a surface region; forming a first dielectric material overlying the surface region; forming a first wiring material overlying the first dielectric material; forming a switching material comprising an amorphous intrinsic silicon material overlying the first wiring material; subjecting the first wiring material and the switching material to a first pattern and etch process to form a plurality of first structures, each of the plurality of first structures comprising at least a first wiring structure being spatially extending in a first direction and a switching material having a surface region; depositing a second dielectric material overlying at least the plurality of first structures to form a thickness of second dielectric material overlying the switching material of each of the plurality of first structures, the second dielectric material comprising a surface region; forming an opening region in a portion of the thickness of second dielectric material, exposing a portion of the surface region of the switching material; and selectively forming a silver material in a portion of the opening region to at least partially fill the opening region while the surface region of the second dielectric material being free of attachment of the silver material.
