Claim 7:
8. A structure comprising:
a first fin and a second fin over a substrate;
a first gate structure extending along opposing sidewalls and a top surface of the first fin;
a second gate structure extending along opposing sidewalls and a top surface of the second fin;
a first insulating structure adjacent the first gate structure, wherein a width of the first insulating structure increases as the first insulating structure extends away from the substrate;
a second insulating structure adjacent the second gate structure, wherein a width of the second insulating structure increases as the second insulating structure extends away from the substrate; and
a third insulating structure between and contacting the first insulating structure and the second insulating structure, wherein a width of the third insulating structure decreases as the third insulating structure extends away from the substrate.
