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 1):
A semiconductor device, comprising:\n a base substrate; a first dielectric layer on the base substrate, with a first groove through the first dielectric layer; a first gate electrode in the first groove, with a top surface lower than a top surface of the first dielectric layer; a first protective layer on a portion of the top surface of the first gate electrode, the first protective layer having a first oxygen ionic concentration; a compensating protective layer on a remaining portion of the top surface of the first gate electrode exposed by the first protective layer, the compensating protective layer having a second oxygen ionic concentration; and a second dielectric layer on the first protective layer, on the compensating protective layer and on the first dielectric layer, wherein a material of the second dielectric layer has a third oxygen ionic concentration greater than each of the first oxygen ionic concentration and the second oxygen ionic concentration.
