Patent ID: 8530971

Claim:
A semiconductor device comprising: a substrate; a borderless contact comprised of a metal; a gate structure on the substrate; a first spacer disposed between the gate structure and the borderless contact and comprised of a first spacer material; an interlevel dielectric that at least partially overlies the gate structure; a second spacer disposed between at least a portion of the gate structure and the interlevel dielectric and comprised of a second spacer material that is different from the first spacer material, where the first spacer and the second spacer are on different sides of the gate structure, where the second spacer comprises a nitride and the first spacer comprises a low-K dielectric material; and a third spacer between the interlevel dielectric and the borderless contact, where the third spacer is spaced from the first spacer and comprises a low-K dielectric material, wherein the third spacer is comprised of the same first spacer material as the first spacer.
