摘要： A magnetic recording medium, which includes a substrate and an amorphous magnetic layer, made of an amorphous magnetic material, for magnetic recording of data, is provided with an underlayer between the substrate and the amorphous magnetic layer, the underlayer being made of amorphous metal element, and having a mean thickness of 10 nm or less. In this manner, movement of magnetic domain walls of the amorphous magnetic layer is effectively limited by minute irregularities on a surface of the underlayer. This realizes a stable formation of a minute recording mark. This realizes recording having a sufficient signal quality, even when the high-density recording is performed by forming such a minute recording mark that a shortest length of the recording mark is less than 100 nm. Moreover, this allows the magnetic recording medium to have a simplified layer structure. Further, a magnetic recording apparatus magnetically records data onto a magnetic recording medium having the above arrangement, by heating a portion of the magnetic layer by radiating a light beam locally, and by applying a magnetic field on at least part of the portion of the magnetic layer on which the light beam is radiated. This provides a magnetic recording apparatus for high-density recording.

摘要： In a method of forming a track width defining layer including a magnetic pole portion, a base film is initially formed on a write gap layer. The base film includes a first layer made of a magnetic material having a saturation magnetic flux density of 1.8 T or more, and a second layer formed on the first layer and made of a magnetic material. The magnetic material forming the second layer is a material containing Fe or Ni as a main component and without containing Co. Then, a frame having an opening of a shape matching with the track width defining layer is formed on the second layer. Subsequently, the track width defining layer is formed within the opening by electroplating, using the base film as an electrode.

摘要： For the purpose of providing a semiconductor and its manufacturing that can attain local smoothing by removing local defective surface morphology while attaining global surface smoothing, a substrate surface is smoothed by conducting chemical mechanical polishing in a plurality of separate steps using different types of slurry which are different in degree of dispersion of abrasive particles. For example, chemical mechanical polishing is first conducted by using non-suspension-type slurry, and chemical mechanical polishing is next conducted by using suspension-type slurry. By polishing a Cu film, for example, by using this chemical mechanical polishing, a plug is made in a via hole.

摘要： The flux density Bct is applied at the center area of the electrode. The flux density Bct is adjusted within the range A of 0.75 to 0.9 times greater than the axial flux density Bcr which gives the lowest arc voltage between the electrodes against each breaking current. The axial flux density monotonously increases from the center to the circumferential area of the electrode. Here, the radial position where the axial flux density Bcr which gives the lowest arc voltage Vmin is adjusted within the region B of 20% to 40% of the radius of the electrode. The axial flux density is made monotonously increase in an outer area from the region B and give the maximum value Bp in a circumferential area equal to or beyond 70% of the radius of the electrode. The maximum value Bp is adjusted within the range C of 1.4 to 2.4 times greater than the flux density Bct given at the electrode center.

摘要： A process for detecting fine particles includes the steps of forming a sublimable thin film on an essential surface of a wafer on which fine particles are present, irradiating laser beam at the surface of the wafer, receiving a reflected beam from the surface which is scattered by the presence of the fine particles, and detecting the particles from the received scattered beam. The process may further include the step of accomplishing an etchback against the sublimable film to partially retain the sublimable film adjacent the surface of the fine particles. The film can be prepared from one or a mixture of gas including free sulfur generatable gas under discharge-dissociation conditions. Sulfur compounds or polythiazyl are preferable. Alternatively, the film can be made of a condensed film of organic solvent vapor. The sublimable film is sublimed by heating after the step of detecting the fine particles.

摘要： A small-sized electric motor includes a yoke formed by bending a rectangular metallic plate into an oval shaped tube having a pair of flat parts and a pair of arcuate parts and joining opposite ends of the metallic plate. An end cap is secured on one end of the yoke and a gear casing is secured to the yoke by a tab formed on another end of the yoke. The joining faces of the metallic plate are located away from the center line of an arcuate part of the yoke and jagged faces are formed on the joining faces. The jagged faces are composed only of curved parts and straight parts having inclinations to the axis of the yoke. The end cap is secured by crimping a bendable tab formed on one end of the yoke by burring. A tab for securing the yoke to a gear box is formed by bending a tongue provided on the metallic plate together with notches on both sides of the tongue.
