Current sensor comprising a magnetoresistive tape and its production process

Process for the production of a current sensor incorporating a magnetoresistive tape having ends for connection to a device for measuring the current, comprising the following stages:

• deposition on one face of an insulating substrate of a conductive, metallic layer,
• etching the conductive, metallic layer to form the ends of the tape,
• deposition of a conductive, magnetic material layer on said face,
• etching said conductive, magnetic material layer to obtain a sequence of aligned, separated, conductive, magnetic elements located between said ends,
• deposition on said face of a metallic, multilayer, magnetic structure layer,
• etching said metallic, multilayer, magnetic structure layer to obtain elements solely between the magnetic elements and so as to ensure the electrical continuity between said ends.
