    • A magnetoresistive device comprises: a first shield layer and a second shield layer disposed with a space from each other in the direction of thickness; an MR element disposed between the first and second shield layers; and a layered structure disposed between the first and second shield layers on both sides of the MR element. The layered structure includes an insulating layer and bias field applying layers. The second shield layer has a surface facing toward the first shield layer. This surface includes a first portion touching the top surface of the MR element and second portions located on both sides of the MR element, the sides being opposed to each other in the direction of track width. A difference in level is created between the first and second portions such that the second portions are closer to the first shield layer than the first portion.
    • 磁阻装置包括:第一屏蔽层和第二屏蔽层,其在厚度方向上彼此具有空间; 设置在第一和第二屏蔽层之间的MR元件; 以及设置在MR元件的两侧上的第一和第二屏蔽层之间的分层结构。 层状结构包括绝缘层和偏置场施加层。 第二屏蔽层具有面向第一屏蔽层的表面。 该表面包括接触MR元件的顶表面的第一部分和位于MR元件两侧的第二部分,所述侧面在轨道宽度方向上彼此相对。 在第一部分和第二部分之间产生水平差,使得第二部分比第一部分更靠近第一屏蔽层。

    • A manufacturing method for a crystalline semiconductor material including a plurality of semiconductor crystal grains is provided. The manufacturing method includes forming an amorphous or polycrystalline semiconductor layer on a substrate having a flat surface; forming a plurality of projections each having a side wall surface substantially perpendicular to the flat surface of the substrate, a height set in the range of about 1 nm to less than or equal to about ¼ of the thickness of the semiconductor layer, and a lateral dimension set in the range of about 3 μm to about 18 μm in a direction parallel to the flat surface of the substrate; and heating the semiconductor layer a number of times by using a pulsed laser thereby forming the crystalline semiconductor material including the crystal grains each having a specific plane orientation with respect to a direction perpendicular to the flat surface of the substrate so that the crystal grains respectively correspond to the projections. Accordingly, the position, size, and plane orientation of a crystal can be controlled by a simple step, and a crystalline semiconductor material excellent in planarity as a film can be formed.
