Abstract:
1. A method of forming a semiconductor structure comprising: providing at least one gate stack on a surface of a substrate, wherein metal semiconductor alloy portions are located adjacent to the at least one gate stack; forming a photo-patternable dielectric material on said at least one gate stack, said metal semiconductor alloy portions and exposed portions of the substrate, wherein the photo-patternable dielectric material comprises a functionalized polymer, copolymer or blend including at least two of any combination of polymers and/or copolymers having one or more acid-sensitive imagable groups; patterning the photo-patternable dielectric material by employing a direct pattern-wise exposure step and without utilizing a pattern transfer etch to provide a sacrificial contact structure comprising a remaining portion of the photo-patternable dielectric material located directly on a surface of at least one of the metal semiconductor alloy portions; forming a planarized middle-of-the-line dielectric material, wherein an uppermost surface of the sacrificial contact structure is exposed; removing the exposed sacrificial contact structure to provide a contact opening; and filling the contact opening with a conductive metal-containing material, wherein said conductive metal-containing material forms a metal contact.
