Abstract:
A method, comprising:forming a layer of dielectric material; forming a layer of photoresist on said layer of dielectric material; defining a photoresist feature in said layer of photoresist, said feature having a first size; reducing the first size of said photoresist feature to produce a reduced size photoresist feature defining an area; partially etching said layer of dielectric material to define a plurality of recesses in said layer of dielectric material adjacent said reduced size photoresist feature; forming a hard mask layer above said partially etched layer of dielectric material; planarizing said hard mask layer to expose a portion of said partially etched dielectric layer between said recesses; etching said layer of dielectric material in said area defined by said exposed portions of said dielectric layer to define an opening in said layer of dielectric material; and forming a conductive material in said opening.
