Abstract
Aspects for notched gate structure fabrication are described. The notched gate fabrication includes forming spacers of hard mask material on a gate conductor, and utilizing the spacers during etching to form notches in the gate conductor and provide a notched gate structure. In a further aspect, notched gate fabrication includes performing a timed etch of masked gate conductive material to maintain a portion of a gate conductive layer and provide gate structure areas in the gate conductive layer. Anisotropically etching the gate structure areas provides spacers on the gate structure areas. Isotropically etching the portion of the gate conductive layer provides notched gates in the gate structure areas.
