Abstract:
A process for forming a damascene local interconnect over a set conductor substrate having first and second active areas which are isolated from each other, said process comprising the steps of:(a) forming a first dielectric layer over the substrate surface;(b) forming an interconnection in the upper level of the dielectric layer which spans over said first and second active areas;(c) forming a second dielectric layer over the first dielectric layer and the interconnection;(d) etching first and second contact holes adjacent to the opposite ends of the interconnection through said second and first dielectric layers, said first and second contact holes extending down to said first and second active areas respectively; and(e) filling said first and second contact holes with first and second conductive plugs respectively, wherein the interconnection thereby connects the first and second conductive plugs to couple the first and second active areas.
