摘要： Provided is a thin-film magnetic head in which the concentration of magnetic flux in the shield layer and the magnetic pole layer is suppressed. The thin-film magnetic head comprises a plurality of magnetic layers that have front surfaces reaching a head end surface on the ABS side. Further in this head, at least one of the plurality of magnetic layers has a shape in which: each of edges corresponding to both side surfaces extends so as to spread obliquely rearward with each other from an end of a straight edge in a track width direction corresponding to the front surface; and the front surface reaching the head end surface has a shape in which upper and lower corner portions in each of both end portions in the track width direction form obtuse angles or rounded shapes.

摘要： An alignment method of mask patterns in patterning processes includes forming a first layer by transferring a first mask pattern onto a wafer or a layer formed on the wafer, and forming a second layer by transferring a second mask pattern onto the first layer. The method particularly includes a first alignment step of performing, when forming the first layer, alignment for minimizing offset between a center position of the wafer and a center position of the first mask pattern and a residual rotation error between the wafer and the first mask pattern, and alignment based on an amount of deviation of superposition of the second layer pattern on the first layer pattern. The deviation is caused by linear expansion and contraction of a wafer and caused by an orthogonal error between a wafer and a mask pattern, and also the deviation is obtained by measuring in advance in pattering processes successively performed for a plurality of wafers. The method also includes a second alignment step of performing, when forming the second layer, only alignment for minimizing offset between a center position of the first layer pattern and a center position of the second mask pattern and a residual rotation error between the first layer pattern and the second mask pattern.

摘要： Provided is a planarizing method in which a planarization with high flatness can be performed, without being restricted by the distribution of film thickness in the applied resist film. The planarizing method comprises the steps of: forming a resist film on a film to be planarized formed on a substrate; exposing the resist film with the amounts of exposure light in respective sections into which an area in which the film to be planarized is formed is divided, the amounts of exposure light being determined so as to realize film thicknesses to be left for planarization of the resist film in the respective sections; developing the exposed resist film, to form a resist film pattern with a controlled distribution of film thickness; and etching the resist film pattern and the film to be planarized, until eliminating the thickness amounts to be eliminated of the film to be planarized.

摘要： A thin-film magnetic head includes a slider substrate and a write element. The slider substrate has an air bearing surface at one side thereof. The write element has a recording magnetic pole film. The recording magnetic pole film is disposed on a plane crossing the air bearing surface over the slider substrate and has a large-width portion and a small-width portion continuously arranged in the named order toward the air bearing surface. The small-width portion has a smaller width than the large-width portion. Of the large-width portion and the small-width portion, at least the small-width portion has a first portion and a second portion. The second portion is continuous with an upper end of the first portion and has both side faces inclined in such a direction as to increase the width. An external angle of the first portion formed by a plane parallel to a bottom face and the side face is larger than an external angle of the second portion formed by a plane parallel to the bottom face and the side face.
