Abstract:
1. A structure comprising: a first plurality of conductive lines having a first pitch and embedded in at least one dielectric layer, wherein each of said first plurality of conductive lines has a pair of sidewalls that are parallel to a first vertical plane and an end wall located within a second vertical plane and a bottom surface in contact with a top planar surface of a substrate, wherein an angle between said first vertical plane and said second vertical plane is less than 45 degrees; a plurality of conductive vias, wherein each of said plurality of conductive vias contacts an end portion of one of said plurality of conductive lines and is embedded in said at least one dielectric layer, and wherein said second vertical plane intersects each of said plurality of conductive vias; and a plurality of dielectric material portions having said first pitch and vertically contacting, and spaced from said substrate by, said first plurality of conductive lines, wherein each sidewall of said plurality of dielectric material portions coincides with a plane of a sidewall of first plurality of conductive lines and each end wall of said plurality of dielectric material portions is offset from said second vertical plane by a constant distance.
