Patent ID: 6949386

Claim:
Method for producing in large numbers a multiplicity of magnetic sensors ( 1 ) produced on a semiconductor substrate ( 4 ), these sensors ( 1 ) comprising at least one magnetic core ( 8 ) produced in an amorphous magnetic material, characterised in that, after integration of the electronic circuits associated with the magnetic sensors ( 1 ), a film ( 22 ) of amorphous magnetic material is glued onto the semiconductor substrate ( 4 ), this film ( 22 ) being obtained from a band of amorphous magnetic material cut into a plurality of sections ( 18 ) which are disposed one beside the other on a support ( 20 ), said film being then structured in order to form the magnetic cores ( 8 ) of said magnetic sensors ( 1 ), the semiconductor substrate ( 4 ) being finally cut up in order to provide a plurality of individual magnetic sensors ( 1 ).
