Abstract:
At least one method, apparatus and system disclosed herein involves forming semiconductor devices comprising vertically aligned gates, metal hard masks, and nitride regions. The semiconductor device may contain a semiconductor substrate; a gate disposed on the semiconductor substrate; a metal hard mask vertically aligned with the gate; a nitride region vertically aligned with the gate and the metal hard mask; and source/drain (S/D) regions disposed in proximity to the gate.
