A method of forming an interconnection including the steps of depositing a first masking material over a first conductive region of an integrated circuit substrate and depositing a dielectric material over the first masking material. The method also includes forming a via through the dielectric material to expose the first masking material and a second masking material is deposited in a portion of the via. A trench is formed in the dielectric material over a portion of the via and the second masking material is removed from the via. The via is then extended through the first masking material and a conductive material is deposited in the via.

Photoimageable material patterning techniques useful in fabricating conductive lines in circuit structures

A method of forming an interconnection including the steps of forming a sacrificial material that comprises a physical property that is generally insensitive to a photo-reaction in a via through a dielectric material to a masking material over a conductive material. The method also includes forming a trench over in the dielectric material over the via and removing the sacrificial material from the via.
