SOLUTION: A method for manufacturing a thin-film magnetic head made by forming a 1st and a 2nd magnetic core so as to opposite to each other through a magnetic gap is provided with a 1st magnetic layer forming process for forming a 1st magnetic layer 4 becoming a 1st magnetic core on a base body, a nonmagnetic layer forming process for forming a nonmagnetic layer 6 becoming a magnetic gap on the 1st magnetic layer 4, a 2nd magnetic layer forming process for forming a 2nd magnetic layer 11 in a specific shape becoming a 2nd magnetic core on the nonmagnetic layer 6 and an etching process for making the nonmagnetic layer 6 and 1st magnetic layer 4 integrally in a specific shape by etching the nonmagnetic layer 6 and 1st magnetic layer 4 by using the 2nd magnetic layer as a mask. In the etching process, when the nonmagnetic layer 6 is etched, etching is carried out by reactive ion etching and when the 1st magnetic layer 4 is etched, etching is carried out by ion beam etching.

Abstract:
PROBLEM TO BE SOLVED: To uniformly irradiate a substrate with a beam and to eliminate the variation of the etching quantity within the substrate by largely repetitively turning the substrate in an intra-surface direction in an etching stage using the ion beam. SOLUTION: When the substrate is not turned, the substrate is irradiated with the ion beam 30 approximately parallel with the longs side on the upper surface of a second pole 8. The substrate is repetitively turned and moved back and forth between the position of 180 deg. in a plus direction and a position of 180 deg. in a minus direction. As the substrate is turned, the irradiation direction of the ion beam 30 with second pole 8 changes and the portion which is the shade of the second pole 8 changes accordingly. The direction where the irradiation direction of the ion beam 30 with the second pole 8 is successively varied by repetitively moving the substrate within a specified range. Even if, therefore, the shape of the second pile 8 is asymmetrical on the front side and the rear side, the uniform irradiation with the ion beam 30 is made possible.

PROBLEM TO BE SOLVED: To provide a method for manufacturing a thin-film magnetic head whose the record fringing is reduced by preventing a nonmagnetic layer and a 1st magnetic body which are left at the time of trim etching and removed matters from being restuck. SOLUTION: This method is provided with a 1st magnetic body forming process for forming a 1st magnetic body 4 becoming a 1st magnetic core on a base body, a nonmagnetic layer forming process for forming a nonmagnetic layer 6 becoming a magnetic gap on the 1st magnetic body, a 2nd magnetic body forming process for forming a 2nd magnetic body 11 in a specific shape becoming a 2nd magnetic core on the nonmagnetic layer 6 and an etching process for making the nonmagnetic layer 6 and the 1st magnetic body 4 integrally in a specific shape by ion beam etching by using the 2nd magnetic body 11 as a mask. Then, in the etching process, 1st etching is carried out while the base body is slanted at a specific angle to the incidence direction of the ion beam and is repeatedly rotated within a specific angle range and 2nd etching is carried out while the base body is slanted within an angle range larger than that of the 1st etching and is repeatedly rotated within an angle range larger than that of the 1st etching.
