Abstract:
Semiconductor device and fabrication method are provided. The method includes: providing a base substrate; forming gate structures on the base substrate; forming source/drain doped regions in the base substrate on sides of each gate structure, where the source/drain doped regions have recessed top surfaces and are doped with source/drain ions; and doping into the recessed top surfaces of the source/drain doped regions with contact ions to form contact doped regions in top portions of the source/drain doped regions, where the contact ions have a conductivity type same as the source/drain ions.

Claim (Index 8):
The fabrication method according to  claim 7 , wherein:\n the first compensating doped regions include first compensating layers, in the base substrate under the source/drain doped regions, and second compensating layers, in the base substrate between the first compensating layers and the source/drain doped regions; wherein: the first compensating layers have first compensating ions with a first concentration less than the concentration of the source/drain ions in the source/drain doped regions; the second compensating layers have second compensating ions with a second concentration greater than the first concentration and less than the concentration of the source/drain ions in the source/drain doped regions; and the first compensating doped regions are formed by:\n doping the base substrate under the initial source/drain doped regions with the first compensating ions to form the first compensating layers with the first concentration less than the concentration of the source/drain ions in the source/drain doped regions, having a portion of the base substrate between the first compensating layers and the initial source/drain doped regions; and \n doping a portion of the base substrate between the first compensating layers and the initial source/drain doped regions with the first compensating ions to form the second compensating layers with the second concentration greater than the first concentration and smaller than the concentration of the source/drain ions in the source/drain doped regions.
