Abstract
An integrated circuit (IC) structure includes a dielectric layer extending along a first axis to define a length and a second axis orthogonal to the first axis to define a width. A dual-metal via is embedded in the dielectric layer. The dual-metal via includes via sidewalls surrounding a via core. An electrically conductive line extends along the first axis and on an upper surface of the dual-metal via. A side portion of the via core is co-planar with a sidewall of the electrically conductive line.
