    • PROBLEM TO BE SOLVED: To provide a forming method for a resist pattern in which a three dimensional shape of the resist pattern can sufficiently be controlled. SOLUTION: After a preparatory resist pattern 63 having a projection part 63T at a position P3 corresponding to a flare point is formed by selectively exposing and developing a resist film, the preparatory resist pattern 63 is heated to form a resist pattern for forming a main magnetic pole layer. In the heating process, an influence of thermal contraction is reduced because the projection part 63T is formed on the preparatory resist pattern 63, so the preparatory resist pattern 63 is not apt to become round at the position P3. Further, the preparatory resist pattern 63 has thermal flow and thermal contraction in the heating process and then while an internal wall of an opening part 63K tilts, the projection part 63T moves back. Consequently, a photoresist pattern is nearly in a desired three dimensional shape. COPYRIGHT: (C)2008,JPO&INPIT
    • 要解决的问题:提供可以充分地控制抗蚀剂图案的三维形状的抗蚀剂图案的形成方法。 解决方案:在通过选择性地曝光和显影抗蚀剂膜形成具有突起部分63T在与扩张点相对应的位置P3处的预备抗蚀剂图案63之后,加热预备抗蚀剂图案63以形成抗蚀剂图案以形成 主磁极层。 在加热过程中,由于突起部63T形成在预备抗蚀图案63上,因此预备抗蚀剂图案63在位置P3处不易变圆,所以热收缩的影响减小。 此外,准备抗蚀剂图案63在加热过程中具有热流和热收缩,然后在开口部63K的内壁倾斜的同时,突出部63T向后移动。 因此,光致抗蚀剂图案几乎处于所需的三维形状。 版权所有(C)2008,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a method for forming a thin-film pattern having a fine pattern width with high accuracy without depending on the resolution limit of an aligner. SOLUTION: This pattern-forming method comprises the steps of: forming a preliminary thin-film pattern (top face 2A and side face 2B) by selectively etching the thin film with the use of a mask pattern having an undercut part; forming an etching protection film so as to cover the top face 2A and side face 2B of the preliminary thin-film pattern; and forming the thin film pattern 7 (side face 2C) by selectively etching the preliminary thin-film pattern by using the etching protection film as a mask. A pattern width of the thin-film pattern 7 is determined on the basis of two side faces 2B and 2C which are formed through the two-step etching process. Besides, the pattern width of the thin-film pattern 7 is controlled on the basis of the width of the top face 2A and a tilted angle of the side faces 2B and 2C, with high precision.

When the pattern membrane is formed so that it has the quadrangular cross-sectional shape in which the two cross-sectional shapes are mutually different, setting accuracy of the two cross-sectional angles is enhanced.

    • PROBLEM TO BE SOLVED: To provide a manufacturing method of a thin film magnetic head capable of both suppressing generation of side erase and securing overwriting characteristics. SOLUTION: A photoresist pattern 35 is formed so that an aperture width of an aperture 35K is gradually narrowed as the aperture approaches a seed layer 12 by exposing a photoresist film to light while a reflection suppressing layer 31 is formed in an area F1 to perform patterning and then a precursor magnetic pole partial layer 13AZ is formed in the aperture 35K of the photoresist pattern 35. Since relative difference in the exposure range of the photoresist film is generated based on existence of the reflection suppressing layer 31 between the area F1 and an area F2, a tilt angle ωR of a defined surface 35RM of the photoresist pattern 35 is made larger than a tilt angle ωL of a defined surface 35LM. Thereby, the precursor magnetic pole partial layer 13AZ is formed so that its sectional shape is asymmetrical reversed trapezoidal shape reflecting size relation between tilt angles ωR and ωL.

    • PROBLEM TO BE SOLVED: To provide a method for manufacturing a thin-film magnetic head that can both suppress side erasure and secure overwriting characteristics. SOLUTION: When a magnetic pole part layer is formed as a discharge part for magnetic flux, a photoresist pattern 33 is formed so that two frame parts 33R and 33L sectioning an opening 33K have different width from each other, and heated to deform the frame parts 33R and 33L, and thus the width of the opening 33K is made gradually narrower toward a seed layer 12; and then a pre-drive magnetic pole part layer 13AZ is formed in the opening 33K of the photoresist pattern 33 and polished to form an air bearing face, thereby forming the magnetic pole part layer so that an exposure surface exposed in the air bearing surface is in a right-left asymmetrical inverted trapezoid shape. Based upon the shape feature of the exposure surface, suppression of side erasure and securing of overwriting characteristics are both realized. COPYRIGHT: (C)2005,JPO&NCIPI
