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.

Claim (Index 1):
A semiconductor device, comprising:\n a first semiconductor device comprising:\n a pair of first source/drain regions disposed in a semiconductor substrate, wherein the first source/drain regions are laterally spaced; \n a first gate electrode disposed over the semiconductor substrate and between the first source/drain regions; and \n first sidewall spacers disposed over the semiconductor substrate and on opposite sides of the first gate electrode; \n a second semiconductor device comprising:\n a pair of second source/drain regions disposed in the semiconductor substrate and spaced from the pair of first source/drain regions, wherein the second source/drain regions are laterally spaced; \n a second gate electrode disposed over the semiconductor substrate and between the second source/drain regions; and \n second sidewall spacers disposed over the semiconductor substrate and on opposite sides of the second gate electrode; \n a contact etch stop layer (CESL) disposed over the semiconductor substrate, along the first sidewall spacers, and along the second sidewall spacers, wherein the CESL directly contacts the second sidewall spacers; and a silicide blocking structure disposed along the first sidewalls spacers, wherein the silicide blocking structure separates the first sidewall spacers from the CESL.
