Abstract:
A method for fabricating semiconductor device is disclosed. The method includes the steps of : providing a substrate; forming a first gate structure on the substrate; forming a first contact plug adjacent to the first gate structure; and performing a replacement metal gate (RMG) process to transform the first gate structure into metal gate.
