Patent ID: 7678658

Claim:
A method of forming a static random access memory (SRAM) interconnect structure, the method comprising: forming a sidewall spacer around a periphery of a patterned poly-silicon layer formed over a silicon layer of a semiconductor substrate; etching a portion of said silicon layer, in which said portion of said silicon layer connects at least a portion of a pull-down device of said SRAM to said at least a portion of a pull-up device of said SRAM; forming a gate oxide; forming a gate conductor over said gate oxide, wherein said forming said sidewall spacer includes depositing a cap layer on said silicon layer; depositing a poly-silicon layer on said cap layer; patterning said poly-silicon layer to reveal a portion of said cap layer for producing a sidewall of said poly-silicon layer; and forming a spacer on said sidewall of said poly-silicon layer.
