Claim Text:
1. A FinFET device comprising a channel region and a plurality of source/drain regions, the device comprising: a fin structure comprised of a semiconductor material; a substantially U-shaped insulating material structure comprised of one or more layers of insulating material, said substantially U-shaped insulating material structure defining a recess between spaced-apart vertically oriented legs of said U-shaped insulating material structure, wherein, in a cross sectional view of said device taken through said fin structure in a current transport direction, the device further comprises spaced-apart portions of a separate layer of material positioned between an upper surface of said fin structure and spaced-apart portions of insulating material of which said substantially U-shaped insulating material structure is comprised; a replacement gate structure positioned in said recess in said substantially U-shaped insulating material structure and around a portion of said fin structure; and a gate cap positioned above said replacement gate structure and within said recess in said substantially U-shaped insulating material structure.
