Abstract:
A semiconductor device and fabrication method are provided. The method includes providing a first dielectric layer with a first groove on a base substrate. A first gate electrode is formed in the first groove, with a top surface lower than the first dielectric layer. A first protective layer is formed on a portion of the top surface of the first gate electrode, with a first oxygen ionic concentration. A compensating protective layer is formed on a remaining portion of the top surface of the first gate electrode exposed by the first protective layer, with a second oxygen ionic concentration. A second dielectric layer is formed on the first protective layer, on the compensating protective layer, and on the first dielectric layer, with a third oxygen ionic concentration. The first oxygen ionic concentration and second oxygen ionic concentration are smaller than the third oxygen ionic concentration.

Claim (Index 9):
The semiconductor device according to  claim 5 , further including:\n a first work function layer; a first gate dielectric layer on the first work function layer; a second work function layer; and a second gate dielectric layer on the second work function layer, wherein: the first work function layer is located on a bottom and on a portion of the sidewalls of the first groove; the first work function layer has a top surface coplanar with the top surface of the first gate electrode; the first gate dielectric layer is located on the bottom of the first groove, and between the base substrate and the first work function layer; the second work function layer is located on a bottom and on a portion of the sidewalls of the second groove; the second work function layer has a top surface coplanar with the top surface of the second gate electrode; and the second gate dielectric layer is located on the bottom of the second groove and between the base substrate and the second work function layer.
