Abstract:
A multilevel interconnect structure comprisinga first level of interconnect arranged on a semiconductor substrate;a first dielectric layer arranged upon said first level of interconnect, said first dielectric layer having a trench extending downwardly from an upper surface of said dielectric, said trench partially filled with a conductive material such that an upper surface of said conductive material is vertically below the upper surface of said first dielectric layer, said conductive material forming a local connector;a second dielectric layer formed on said local connector such that said second dielectric layer is laterally defined within said trench; andfirst and second conductors of a second level of interconnect formed on said first dielectric layer such that a lower surface of said first and second conductors is vertically displaced above the upper surface of said local connector, and said first and second conductors are horizontally displaced from said local connector by a lateral distance whereby said local connector is displaced from said first and second conductors by a distance of approximately the square root of the sum of said lateral distance squared and said vertical distance squared.
