Abstract
A semiconductor device includes first and second semiconductor fins, first, second, third and fourth gate structures, and a dielectric structure. The first semiconductor fin and the second semiconductor fin are over a substrate. The first gate structure and the second gate structure respectively extend across the first semiconductor fin and the second semiconductor fin. The first gate structure has a longitudinal axis aligned with a longitudinal axis of the second gate structure. The dielectric structure interposes the first gate structure and the second gate structure. The third gate structure extends across the first and second semiconductor fins. The fourth gate structure extends across the first and second semiconductor fins. The third gate structure is between the fourth gate structure and the dielectric structure. The third gate structure has a maximal width greater than a maximal width of the fourth gate structure.
