Claim Text:
1. A method of forming a magnetoresistive device, comprising: forming a spacer layer over a dielectric layer; forming a first electrically conductive layer over the spacer layer, wherein after the first electrically conductive layer is formed, the spacer layer is between the first electrically conductive layer and the dielectric layer; forming a patterned layer of photoresist over the first electrically conductive layer; etching the first electrically conductive layer not covered by the patterned layer of photoresist to form a first electrode; stripping the patterned layer of photoresist using a non-oxidizing gas; and after stripping the patterned layer of photoresist and etching the first electrically conductive layer, etching the dielectric layer not covered by the first electrode to form an etched dielectric layer.
