Abstract
The present invention relates to a methodology of fabricating a local interconnect. The methodology includes the steps of forming an organic stop layer over a semiconductor structure having at least one conductive region, forming an insulating layer over the organic layer, forming a photoresist layer over the insulating layer, patterning the photoresist layer with at least one opening above the at least one conductive region, etching at least one opening in the insulating layer, concurrently stripping the photoresist layer and an exposed portion of the organic layer and filling the at least one opening with a conductive material to form the local interconnect.
