摘要： An interconnect structure is disclosed. The interconnect structure includes a first metal interconnect in a bottom dielectric layer, a via that extends through a top dielectric layer, a metal plate, an intermediate dielectric layer, and an etch stop layer, and a metal in the via to extend through the top dielectric layer, the metal plate, the intermediate dielectric layer and the etch stop layer to the top surface of the first metal interconnect. The metal plate is coupled to an MIM capacitor that is parallel to the via. The second metal interconnect is on top of the metal in the via.

摘要： An integrated circuit includes a base, a first transistor structure on or above the base, and a second transistor structure on or above the base, where the second transistor structure is spaced from the first transistor structure. An insulator material at least partially encapsulates an airgap or other gas pocket laterally between the first transistor structure and the second transistor structure. The gas pocket is at least 5 nm in height and at least 5 nm wide according to an embodiment, and in some cases is as tall or taller than active device layers of the transistor structures it separates.
