PROCEDE DE REALISATION COLLECTIVE DE TETES MAGNETIQUES INTEGREES A SURFACE PORTANTE OBTENUE PAR PHOTOLITHOGRAPHIE

摘要

The invention concerns a method which consists in depositing on a wafer (50) containing a plurality of heads, a mask (60) defining the profile of the bearing surfaces (62) and in collectively etching the wafer in the proximity of the polar parts of the heads. The invention is useful for producing magnetic heads.
