摘要： When first and second near-field light-generating portions are irradiated with laser light or other energy rays, near-field light is generated at the tips of both the near-field light-generating portions. By means of the near-field light thus generated, a magnetic recording medium opposing the medium-opposing surface is heated, and the coercivity of the magnetic recording medium is lowered. Since at least a portion of the main magnetic pole is positioned within the spot region including the region between the first and second near-field light-generating portions, the tips of both the near-field light-generating portions and the main magnetic pole can be brought extremely close together, and high-density recording can be performed.

摘要： The present invention provides a magnetic memory device capable of stably performing information writing operation by efficiently using a magnetic field generated by current flowing in write lines and having a high degree of flexibility in designing. A magneto-resistive element has: a magnetic yoke disposed annularly in a circumferential direction so as to surround a write word line and a write bit line, and having a pair of open ends facing each other while sandwiching a gap provided in a part in the circumferential direction; and a stacked body including a second magnetic layer of which magnetization direction changes according to an external magnetic field and a pair of end faces. The stacked body is disposed in the gap so that each of the pair of end faces and each of the pair of open ends face each other. With the configuration, magnetization of the second magnetic layer can be efficiently inverted and, as compared with the case where the stacked body and the magnetic yoke are in contact with each other, the material of the stacked body can be selected from a wider range and the magnetic and electric performances of the stacked body can be sufficiently displayed.

摘要： For each of pattern projection regions, a mask and a substrate are moved in synchronization with each other in an X direction while projecting a portion of a mask pattern through an optical projection system onto a portion of the pattern projection region. An exposure region is thereby shifted from one of two ends of the pattern projection region toward the other end, the two ends being opposed to each other in the X direction. If the pattern projection region is a peripheral projection region that has a portion located outside the edge of the substrate, of the two ends of the region opposed to each other in the X direction, the exposure region is shifted from the one end that is greater in length of a portion laid over the substrate toward the other end.

摘要： The present invention provides a magnetic memory device capable of performing stable operation efficiently using a magnetic field generated by write current and formed with high precision while realizing a compact configuration. Since a plating film is used for at least a part of a magnetic yoke, as compared with the case of formation by a dry film forming method, sufficient thickness and higher dimensional precision can be obtained. Consequently, a more stabilized return magnetic field can be generated and high reliability can be assured. Neighboring memory cells can be disposed at narrower intervals, so that the invention is suitable for realizing higher integration and higher packing density.

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.

摘要： A resist pattern processing apparatus comprises a stage for mounting a substrate having a patterned photoresist arranged on a surface thereof, a UV-emitting part for emitting UV rays to the stage, and an annular member for surrounding the whole periphery of the substrate. This allows the annular member to restrain ozone supplied near a mounting surface for the substrate on the stage from diffusing to the periphery of the stage, whereby the ozone concentration becomes even in the surface of the substrate mounted on the stage.
