Abstract:
The semiconductor structure includes a semiconductor substrate having a first region and a second region being adjacent to the first region; first fins formed on the semiconductor substrate within the first region; a first shallow trench isolation (STI) feature disposed on the semiconductor substrate within the second region; and a first gate stack that includes a first segment disposed directly on the first fins within the first region and a second segment extending to the first STI feature within the second region. The second segment of the first gate stack includes a low resistance metal (LRM) layer, a first tantalum titanium nitride layer, a titanium aluminum nitride layer, and a second tantalum titanium nitride layer stacked in sequence. The first segment of the first gate stack within the first region is free of the LRM layer.

Claim (Index 16):
A semiconductor structure, comprising:\n a semiconductor substrate having a first region and a second region; first fins disposed on the semiconductor substrate within the first region and second fins disposed on the semiconductor substrate within the second region; a first gate stack disposed directly on the first fins, wherein the first gate stack includes a first tantalum titanium nitride layer, a titanium aluminum nitride layer, a second tantalum titanium nitride layer, and a low resistance metal (LRM) in sequence; and a second gate stack disposed directly on the second fins, wherein the second gate stack is free of the LRM and includes the first tantalum titanium nitride layer and the titanium aluminum nitride layer, wherein the LRM includes at least one of tungsten, copper, aluminum, and copper aluminum alloy.
