Semiconductor devices and fabrication methods thereof
A semiconductor device includes a base substrate including an NMOS region and a PMOS region. The PMOS region includes a first P-type region and a second P-type region. The semiconductor device also includes an interlayer dielectric layer, a gate structure formed through the interlayer dielectric layer and including an N-type region gate structure formed in the NMOS region, a first gate structure formed in the first P-type region and connected to the N-type region gate structure, and a second gate structure formed in the second P-type region and connected to the first gate structure. The direction from the N-type region gate structure to the second gate structure is an extending direction of the gate structure, and along a direction perpendicular to the extending direction of the gate structure, the width of the first gate structure is larger than the width of the second gate structure.
