Abstract:
A FinFET structure with a gate structure having two notch features therein and a method of forming the same is disclosed. The FinFET notch features ensure that sufficient spacing is provided between the gate structure and source/drain regions of the FinFET to avoid inadvertent shorting of the gate structure to the source/drain regions. Gate structures of different sizes (e.g., different gate widths) and of different pattern densities can be provided on a same substrate and avoid inadvertent of shorting the gate to the source/drain regions through application of the notched features.

Claim (Index 18):
A FinFET device comprising:\n at least one fin extending in a first longitudinal direction; a gate structure extending in a second longitudinal direction perpendicular to the first longitudinal direction, the gate structure having a notched profile when viewed in cross-section along the first longitudinal direction, the notched profile including:\n a first portion extending above the at least one fin top surface, the first portion having a sidewall that slopes from a first width W 1  at a top height to a second width W 2  at a bottom height; and \n a second portion extending along a sidewall of the at least one fin, the second portion having a sidewall that slopes from the second width W 2  at the top of the second portion to a third width W 3  at a point a first distance H 3  below the top of the second portion to a fourth width W 4  at a point a second distance H 2  below the top of the second portion; and \n wherein the following conditions are met by the profile of the gate structure:\n W 1> W 2> W 3, \n H 1> H 2, \n H 3= H 2/2, and \n 0.067\u2264 H 3/( W 2\u2212 W 3)\u226425.
