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 16):
The method according to  claim 13 , wherein the first gate electrode and the second gate electrode are formed by:\n form a gate electrode material layer in the first groove, in the second groove and on the first dielectric layer; polishing the gate electrode material layer to expose the top surface of the first dielectric layer, and to form the first initial gate electrode in the first groove and the second initial gate electrode in the second groove; and etching back the first initial gate electrode and the second initial gate electrode, to form the first gate electrode from the first initial gate electrode and to form the second gate electrode from the second initial gate electrode.
