Abstract
A fabrication method for a metal oxide semiconductor transistor is described. A source/drain implantation is conducted on a substrate beside the spacer that is on the sidewall of the gate to form a source/drain region in the substrate beside the spacer. A self-aligned silicide layer is further formed on the gate and the source/drain region. A portion of the spacer is removed to form a triangular spacer with a sharp corner, followed by performing a tilt angle implantation on the substrate to form a source/drain extension region in the substrate under the side of the gate and the spacer with the sharp corner. A thermal cycle is further conducted to adjust the junction depth and the dopant profile of the source/drain extension region.
