Classification: CPC H  G | IPC G  H

Claim 8:
9. An integrated circuit (IC) structure comprising:
a first dielectric material;
a first gate structure that extends along the first dielectric material in a first direction;
a second gate structure separated from the first gate structure in a second direction by the first dielectric material, the second gate structure extending in the first direction;
a fin structure that extends along the first dielectric material in the second direction and underlies each of the first gate structure and the second gate structure;
a second dielectric material located, at least in part, stacked directly on the fin structure; and
a contact located over the fin structure and, in part, stacked directly on the second dielectric material, wherein the second dielectric material is configured to electrically isolate the contact from the fin structure; and
a first via stacked directly on the contact and located over the fin structure,
wherein
the contact is located between the first and second gate structures and includes a first thickness adjacent to the second dielectric material and a second thickness between the first via and the second dielectric material,
the first thickness includes a volume of the contact aligned with the second dielectric material in the first direction and contacting the second dielectric material along a plane perpendicular to the first direction,
the second thickness is smaller than the first thickness, and
each of the first gate structure, the second gate structure, and the contact extends a same distance above the first dielectric material in a third direction perpendicular to each of the first direction and the second direction.
