Abstract
The invention relates to a process for producing a plurality of magnetoresistive sensors on the same substrate. The invention particularly has as its object to facilitate a polishing phase of this process. The process of the invention comprises depositing a layer of a magnetoresistive material on a substrate, and then forming in this layer a plurality of magnetoresistive elements. The process further comprises making, at the site of each sensor and before the depositing the magnetoresistive layer, an inclined surface, in such a way that each magnetoresistive element is formed on this inclined surface and exhibits an edge directed outward from the substrate.
