Abstract

The present invention provides an interconnect that can be employed in an integrated circuit. The interconnect includes a metal line located over a substrate, a dielectric layer located over the metal line, and an interconnect located in the dielectric layer, including a landed portion located over the metal line and an unlanded portion located along at least a portion of a lateral edge of the metal line. The unlanded portion is at least partially filled with a polymer, and the landed portion is substantially filled with a conductive material. A method for manufacturing the interconnect is also provided.
