Abstract:
A fabrication process for a thin film magnetic head having a structure in which a coil and a hard-baked photoresist are disposed between a lower magnetic material layer and an upper magnetic material layer, said process comprising:forming a lower magnetic material layer;applying a first negative photoresist which is cured by irradiation of a light on said lower magnetic material layer;irradiating a light on said first negative photoresist through a preliminarily set mask;performing a heat treatment for said first negative photoresist by irradiation of light to form a first portion of said hard-baked negative photoresist;forming said coil on said first portion of said hard-baked negative photoresist;applying a second negative photoresist on said coil;setting an insulation pattern layer mask on said second negative photoresist;irradiating a light on said second negative photoresist via said insulating pattern layer mask;performing a heat treatment for said second negative photoresist by irradiation of light to form a second portion of said hard-baked photoresist; andforming said upper magnetic material layer on said hard-baked negative photoresist.
