    摘要: 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.
