摘要： The present invention provides a method of manufacturing a thin film magnetic head, capable of forming a magnetic pole layer as easily as possible. By etching a lower insulating layer and the upper insulating layer by RIE using a fluorine-based gas (CF4 or CHF3) or chlorine-based gas (Cl2 or BCl3), a magnetic pole formation space R1 is formed so as to have a uniform width in an upper insulating layer by and a magnetic pole formation space R2 is formed in the lower insulating layer so as to have a width gradually narrowed from width W1 to width W4 with distance from the magnetic pole formation space R1. After that, a plating film is grown in the magnetic pole formation spaces R1 and R2, thereby forming a main magnetic pole layer. Since the main magnetic pole layer is formed in one process by using the structural characteristics of the magnetic pole formation spaces R1 and R2, the process of forming the main magnetic pole layer is simplified and the number of processes required to form the main magnetic pole layer is reduced.

摘要： Provided is a method of manufacturing a perpendicular magnetic recording head which can enhance accuracy and simplify the manufacturing process. The method includes: forming a photoresist pattern having an opening part; forming a non-magnetic layer so as to narrow the opening part by a dry film forming method such as ALD method; stacking a seed layer and a plating layer so as to bury the opening part provided with the non-magnetic layer; and forming a main magnetic pole layer by polishing the non-magnetic layer, the seed layer, and the plating layer by CMP method until the photoresist pattern is exposed. The final opening width is unsusceptible to variations, thus reducing the number of the steps of forming the main magnetic layer.

摘要： Provided is a method of manufacturing a perpendicular magnetic recording head which can enhance accuracy and simplify the manufacturing process. The method includes: forming a photoresist pattern having an opening part (the inclination of an inner wall); forming a non-magnetic layer (the inclination of another inner wall) so as to narrow the opening part by a dry film forming method such as ALD method; stacking a seed layer and a plating layer so as to bury the opening part provided with the non-magnetic layer; and forming a main magnetic pole layer (a front end portion having a bevel angle) by polishing the non-magnetic layer, the seed layer, and the plating layer by CMP method until the photoresist pattern is exposed. The final opening width (the forming width of the front end portion) is unsusceptible to variations, thus reducing the number of the steps of forming the main magnetic layer.
