Abstract:
A method of fabricating a semiconductor device is disclosed. The method includes forming a first gate structure over a substrate, forming a source/drain feature in the substrate adjacent the first gate structure, forming a dielectric layer over the first gate structure and the source/drain feature, removing a portion of the dielectric layer to form a first trench exposing the first gate structure and the source/drain feature, forming a first conductive feature in the first trench, removing a first portion of the first gate structure to form a second trench and forming a second conductive feature in the second trench.
