Claim 14:
15. A structure comprising:
a substrate comprising a first fin and a second fin, a first longitudinal axis of the first fin being parallel to a longitudinal axis of the second fin;
a first isolation region over the substrate between the first fin and the second fin, wherein the first fin and the second fin protrude above the first isolation region;
a first gate structure comprising a gate dielectric over the first fin and a gate electrode over the gate dielectric;
a first insulating structure abutting the first gate structure, wherein the first insulating structure extends vertically from level with an upper surface of the gate electrode to at least level with a bottom surface of the gate electrode;
a second insulating structure abutting the first insulating structure and extending through the first isolation region, the first insulating structure being between the first gate structure and the second insulating structure; and
a dielectric layer over the first gate structure, the first insulating structure, and the second insulating structure.
