Abstract:
A semiconductor device is provided which includes a semiconductor substrate, a gate structure formed on the substrate, sidewall spacers formed on each side of the gate structure, a source and a drain formed in the substrate on either side of the gate structure, the source and drain having a first type of conductivity, a lightly doped region formed in the substrate and aligned with a side of the gate structure, the lightly doped region having the first type of conductivity, and a barrier region formed in the substrate and adjacent the drain. The barrier region is formed by doping a dopant of a second type of conductivity different from the first type of conductivity.
