Patent ID: 7175972

Claim:
A method for fabricating a thin film magnetic head having a recording element with a first magnetic layer, an insulating film, a coil film and a second magnetic layer, wherein said first magnetic layer and said second magnetic layer constitute a thin film magnetic circuit, and said insulating film is disposed between said first magnetic layer and said second magnetic layer and supports said coil film, and said second magnetic layer is disposed on said insulating film, comprising the steps of: forming a plating underlayer after forming said first magnetic layer, said coil film and said insulating layer and before forming said second magnetic layer, forming an antireflection film on said plating underlayer, heating said antireflection film within 80–150° C. after forming said antireflection film and before applying a photoresist, applying said photoresist over said antireflection film, exposing said photoresist and said antireflection film, heating said antireflection film within 80–150° C. after exposing and before developing said photoresist and said antireflection film, developing said photoresist and said antireflection film to form a resist frame made thereof; and forming said second magnetic layer within an inner pattern enclosed by said resist frame, wherein said antireflection film is made of a material soluble for a developer through exposure.
