Abstract:
Interconnect structures and methods for forming an interconnect structure. A dielectric layer of a metallization level is deposited and a trench is patterned in the dielectric layer. A sacrificial layer is formed in the trench in the dielectric layer. The sacrificial layer is patterned to form a first trench and a second trench separated from the first trench by a section of the sacrificial layer. A first metal interconnect is formed in the first trench, a second metal interconnect is formed in the second trench, and a porous cap layer is formed over the first metal interconnect, the second metal interconnect, and the section of the sacrificial layer. After forming the porous cap layer, the section of the sacrificial layer is removed.

Claim (Index 1):
An interconnect structure comprising:\n a metallization level including a first dielectric layer, a first metal interconnect, a second metal interconnect, and an air gap in a portion of a trench horizontally between the first metal interconnect and the second metal interconnect; a second dielectric layer arranged at a bottom of the trench; a first dielectric spacer arranged adjacent to a first sidewall of the trench between the first metal interconnect and the air gap, the first dielectric spacer extending in a vertical direction relative to the second dielectric layer; a second dielectric spacer arranged adjacent to a second sidewall of the trench between the second metal interconnect and the air gap, the second dielectric spacer extending in a vertical direction relative to the second dielectric layer; and a cap layer over the metallization level, the cap layer having a planar surface above the air gap, the first metal interconnect, and the second metal interconnect, wherein the planar surface of the cap layer is in direct contact with the first metal interconnect and the second metal interconnect.
