Abstract

A method of fabricating a finFET semiconductor device, the method including forming a self-aligned silicide contact above and in direct contact with exposed portions of semiconductor fins not covered by a gate electrode, wherein an upper surface of the self-aligned silicide contact is substantially flush with an upper surface of an adjacent isolation region, patterning a blanket metal layer to form a source-drain contact on the upper surface of the self-aligned silicide contact, the self-aligned silicide contact provides an electrical path from the semiconductor fins to the source-drain contact, and recessing a portion of the self-aligned silicide contact without recessing the isolation region, the self-aligned silicide contact is recessed selective to a mask used to pattern the source-drain contact.
