Abstract:
Interconnect structures and methods for forming an interconnect structure. First and second metallization structures are formed in an intralayer dielectric layer. The intralayer dielectric layer is removed to form a cavity with an entrance between the first and second metallization structures. A dielectric layer is deposited on surfaces surrounding the cavity, over the first metallization structure, and over the second metallization structure. A sacrificial material is formed inside the cavity after the dielectric layer is deposited. A cap layer is deposited on the dielectric layer over the first metallization structure, the dielectric layer over the second metallization structure, and the sacrificial material inside the cavity to close the entrance to the cavity. After the cap layer is deposited, the sacrificial material is removed from the cavity. The dielectric layer and cap layer cooperate to encapsulate an air gap inside the cavity.

Claim (Index 22):
The method of  claim 10  wherein the metallization level further includes a third metallization structure formed in the intralayer dielectric layer, and a fourth metallization structure formed in the intralayer dielectric layer, and the dielectric layer and the cap layer are further deposited over the third metallization structure, the fourth metallization structure, and a portion of the intralayer dielectric layer between the third metallization structure and the fourth metallization structure.
