Abstract

See full text

An interconnect structure includes a first dielectric material having an undercut region located at an upper surface thereof. A first conductive structure is located above a first area of the undercut region. The first conductive structure comprises a first conductive metal portion having a diffusion barrier portion located on one sidewall surface of the first conductive metal portion and having a metal liner located on another sidewall surface and a bottom surface of the first conductive metal portion. A second conductive structure is located above a second area of the undercut region. The second conductive structure comprises a second conductive material portion having a diffusion barrier portion located on one sidewall surface of the second conductive material portion and having a metal liner located on another sidewall surface and a bottom surface of the second conductive metal portion. A gap is located between the first and second conductive structures.
