Claim:
1. A semiconductor structure, comprising: a group of fin structures on a substrate; a dielectric structure on said substrate surrounding said group of fin structures, said dielectric structure on said substrate having a height that is at least as high as that of said group of fin structures, wherein said group of fin structures are part of one or more fin-type field-effect-transistors (FinFETs); at least one gate structure disposed substantially perpendicular to said first group of fin structures with two ends of said at least one gate structure being directly on top of said dielectric structure; and sources and drains on opposing sides of said at least one gate structure and constrained by said dielectric structure, wherein said dielectric structure is not in contact with said group of fin structures and wherein a thickness of said dielectric structure is greater than half of a distance between any two neighboring fins structures of the group of fin structures.
