MAGNET-RESISTIVE MAGNETIC HEAD AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To form a magnetic shielding film with high accuracy and to improve the yield. SOLUTION: This manufacturing method of a magneto-resistive magnetic head which is formed by arranging a magneto-resistance effect element between a pair of magnetic shielding film comprises a stage of forming a resist film which has an opening part corresponding to the shape of the magnetic shielding film, and whose lower layer end part is retreated from the upper layer end part on the opening part when the magnetic shielding film is formed, a stage of forming the magnetic shielding film by using the resist film and a stage of removing the resist film from on the formation surface together with the magnetic shielding film deposited on the resist layer.
