| description | A method of forming a semiconductor device includes forming a first fin and a second fin protruding above a substrate; forming isolation regions on opposing sides of the first fin and the second fin; forming a metal gate over the first fin and over the second fin, the metal gate being surrounded by a first dielectric layer; and forming a recess in the metal gate between the first fin and the second fin, where the recess extends from an upper surface of the metal gate distal the substrate into the metal gate, where the recess has an upper portion distal the substrate and a lower portion between the upper portion and the substrate, where the upper portion has a first width, and the lower portion has a second width larger than the first width, the first width and the second width measured along a longitudinal direction of the metal gate. |
