Claim:
1. A method of manufacturing one or more interconnects to a magnetoresistive structure, the method comprising: depositing a first conductive material (i) in a via which is formed through a first surface of a first dielectric layer and (ii) on a portion of the first surface of the first dielectric layer; etching the first conductive material wherein, after etching, a portion of the first conductive material remains (i) in the via (ii) and on the first surface of the first dielectric layer; depositing a second conductive material in the via and on the first conductive material remaining in the via; depositing a first electrode material on the second conductive material which is in the via; polishing a first surface of the first electrode material wherein, after polishing, the first electrode material is (i) on the second conductive material which is in the via, (ii) over the first conductive material which is in the via, and (iii) over the portion of the first surface of the first dielectric layer; and forming a magnetoresistive structure on the first electrode material.
