Abstract:
A semiconductor device and a fabrication method are provided. The fabrication method includes providing a base substrate including a core region having a first gate structure formed thereon, and an edge region having a second gate structure formed thereon; forming a source/drain doped layer, in the core region of the base substrate on both sides of the first gate structure, and in the edge region of the base substrate on both sides of the second gate structure, respectively, the source/drain doped layer including first ions; and doping the second ions in the source/drain doped layer in the edge region, the second ions having a conductivity type opposite to the first ions.
