Abstract:
1. A method of manufacturing a semiconductor device, the method comprising: providing a workpiece; forming a gate dielectric over the workpiece; forming a gate over the gate dielectric; forming a spacer on sidewalls of the gate and the gate dielectric; forming a source region proximate the spacer on a first side of the gate; forming a drain region proximate the spacer on a second side of the gate, the second side being opposite the first side; removing a portion of the spacers, wherein removing the portion of the spacers comprises undercutting a lower portion of the spacers proximate a top surface of the workpiece and removing a top portion of the spacers; and forming a metal layer over the source region, the drain region, and the gate, wherein the metal layer formed over the source region and the drain region extends beneath the spacers by about 25% or greater than a width of the spacers.
