Abstract

A semiconductor device including a substrate having a NMOS region and a PMOS region; a metal gate extending continuously along a first direction from the NMOS region to the PMOS region on the substrate; a first source/drain region extending along a second direction adjacent to two sides of the metal gate on the NMOS region; a second source/drain region extending along the second direction adjacent to two sides of the metal gate on the PMOS region; a first contact plug landing on the second source/drain region adjacent to one side of the metal gate; a second contact plug landing on the second source/drain region adjacent to another side of the metal gate; and a third contact plug landing directly on a portion of the metal gate on the PMOS region and between the first contact plug and the second contact plug.

Claims (9)

1. A semiconductor device, comprising:

a substrate having a NMOS region and a PMOS region;

a metal gate extending continuously along a first direction from the NMOS region to the PMOS region on the substrate;

a first source/drain region extending along a second direction adjacent to two sides of the metal gate on the NMOS region;

a second source/drain region extending along the second direction adjacent to two sides of the metal gate on the PMOS region;

a first contact plug landing on the second source/drain region adjacent to one side of the metal gate;

a second contact plug landing on the second source/drain region adjacent to another side of the metal gate;

a third contact plug landing directly on a portion of the metal gate on the PMOS region not between the first source/drain region and the second source/drain region, away from a boundary separating the NMOS region and the PMOS region, and near an end of the metal gate on the PMOS region; and

a fourth contact plug landing on the first source/drain region adjacent to one side of the metal gate.
