Abstract
A semiconductor device is provided with an electrically conductive gate having an enhanced gate profile. The semiconductor device includes a semiconductor substrate that extends along a first axis to define a length and a second axis opposite the first axis to define a height. A channel region is interposed between opposing source/drain regions, and a gate stack is atop the semiconductor substrate. The gate stack includes an electrically conductive gate atop the channel region. The electrically conductive gate includes sidewalls extending between a base and an upper surface to define a gate height. A gate length of the electrically conductive gate continuously increases as the gate height increases from the base to the upper surface.
