Abstract

In some embodiments, a semiconductor device is provided. The semiconductor device includes a pair of source/drain regions disposed in a semiconductor substrate, where the source/drain regions are laterally spaced. A gate electrode is disposed over the semiconductor substrate between the source/drain regions. Sidewall spacers are disposed over the semiconductor substrate on opposite sides of the gate electrode. A silicide blocking structure is disposed over the sidewalls spacers, where respective sides of the source/drain regions facing the gate electrode are spaced apart from outer sides of the sidewall spacers and are substantially aligned with outer sidewalls of the silicide blocking structure.
