Magnetoresistive sensor having multi-layered refractory metal conductor leads |
摘要 |
A magnetoresistive sensor having end regions separated from a central active region. The central region comprises magnetoresistive material. Each of the end regions comprises a biasing material for longitudinally biasing the magnetoresistive material in the central region. Each of the end regions also include a lead structure formed over the biasing material for receiving electrical current. The lead structure includes a first refractory metal formed over and in contact with the biasing material; a second refractory metal distinct from the first refractory metal and formed over and in contact with the first refractory metal; and a lead conductor layer formed over and in contact with the second refractory metal. The multi-refractory lead structure has an overall resistance that is much lower than a single refractory metal lead structure.
