Abstract
A semiconductor device includes a semiconductor fin, a gate cut region, a first gate structure and a second gate structure. The semiconductor fin extends from a substrate. The gate cut region extends in parallel with a longitudinal axis of the semiconductor fin and not overlaps the semiconductor fin. The first gate structure and the second gate structure extend across the semiconductor fin. The first gate structure is laterally between the gate cut region and the second gate structure along a direction parallel with the longitudinal axis of the semiconductor fin. The first gate structure has a greater width variation than the second gate structure.
