Abstract:
Embodiments relate to integrated circuit fabrication, and more particularly to a metal gate electrode. An exemplary structure for a semiconductor device comprises a substrate comprising a major surface; a first gate electrode on the major surface comprising a first layer of multi-layer material; a first dielectric material adjacent to one side of the first gate electrode; and a second dielectric material adjacent to the other 3 sides of the first gate electrode, wherein the first dielectric material and the second dielectric material collectively surround the first gate electrode.
