摘要： On the inner surface of a chamber are circumferentially disposed three lateral electrodes at regular intervals. To the lateral electrodes are applied three high-frequency electric powers of 50 MHz, each differing in phase by approximately 120.degree.. On the bottom of the chamber is placed a sample stage serving as a second electrode, around which is provided a ring-shaped earth electrode. To the sample stage is applied high-frequency electric power of 13.56 MHz. The distance between each of the three lateral electrodes and the earth electrode is longer than the distance between the sample stage and the earth electrode.

摘要： After accumulating a BPSG film layer on a silicon substrate, a first Al--Si--Cu film layer, a W film layer and a second Al--Si--Cu film layer are successively accumulated on this BPSG film layer. A resist pattern with wide-width and narrow-width pattern portions is formed on the second Al--Si--Cu film layer. The wide-width pattern portion is provided at a position corresponding to a contact for connecting a first-layer metallic wiring and a second-layer metallic wiring, while the narrow-width pattern portion is provided at a position corresponding to a wiring portion for the first-layer metallic wiring. After applying first etching on the second Al--Si--Cu film layer with a mask of the resist patter, second etching is applied on the W film layer. Thereafter, by applying third etching, the resist pattern remaining on the first-layer metallic wiring is removed and the first Al--Si--Cu film layer is transfigured into a tall metallic film portion and a short metallic film portion. After accumulating an inter-layer insulating film layer on the first Al--Si--Cu film layer, etchback is applied on this inter-layer insulating film layer until the top of the tall metallic film portion is bared. Then, the second-layer metallic wiring is formed on the inter-layer insulating film layer so that the second-layer metallic wiring is connected with the tall metallic film portion.

摘要： A plasma generating method comprises: a first step of disposing a plurality of lateral electrodes at lateral sides of a plasma generating part in a vacuum chamber; a second step of respectively applying, to the lateral electrodes, high frequency electric powers of which frequencies are the same as one another and of which phases are different from one another, thereby to excite, in the plasma generating part, a high frequency rotating electric field to cause electrons under translational motions in the plasma generating part to present oscillating or rotating motions; and a third step of applying, to the plasma generating part, a magnetic field substantially at a right angle to the working plane of the high frequency rotating electric field, thereby to convert the translational movement of the electrons in the plasma generating part into revolving motions under oscillating or rotating motions by which the electrons revolve in the plasma generating part. The high frequency rotating electric field and the magnetic field cause the electrons in the plasma generating part to be confined therein.

摘要： Disclosed is a method of isolating a transistor perfectly by employing a selective oxidation technology (LOCOS technology). More particularly, vertical openings are formed in the surface of {100} silicon substrate, and oxidation resistant films are formed of this surface and in part of the side walls of these openings. In succession, by etching with an etchant having an orientation anisotropy, dents are formed at high precision in the side walls of the openings. By oxidizing using the oxidation resistant film as the mask, an oxide film growing out from a dent in the opening side wall is connected with another oxide film growing out from an adjacent dent. The transistor thus formed in the active region of the silicon electrically isolated from the substrate is small in parasitic capacitance and may be formed into a small size, so that it possesses the features suited to VLSI, that is, high speed, low power consumption, and processability to high density integration.

摘要： A magnetoresistive type thin film magnetic head is completely unaffected by external noise and produces only low interference with a recording medium. A magnetoresistive element which constitutes the thin film magnetic head has three terminals constituted by two end terminals and an intermediate terminal. Constant currents which flow in opposite directions are respectively supplied to the two end terminals. A magnetic field of a signal recorded on and reproduced from a single track of the recording medium is applied to the magnetoresistive element, and reproduction outputs of opposite phases appear at the two end terminals. These outputs are differentially amplified by a differential amplifier. Furthermore, the magnetoresistive element is biased by an induced magnetic anisotropy means in a predetermined direction.

摘要： A thin-film magnetic head having a magnetic substrate made from ferrite, iron-aluminum-silicon alloy or like material, and an upper magnetic layer formed on the magnetic substrate with a lower magnetic layer and a conductive layer interposed therebetween. A portion of the upper magnetic layer is jointed to the magnetic substrate while another portion of the upper magnetic layer is jointed to the lower magnetic layer through a non-magnetic layer of SiO.sub.2 or like material constituting a magnetic gap. The lower magnetic layer, magnetic substrate, upper magnetic layer and the non-magnetic layer in combination form a closed magnetic circuit. A groove is defined between the lower magnetic layer and the magnetic substrate, and formed in the side surface of the magnetic substrate adapted to face a magnetic recording medium. The recess is filled with a non-magnetic material such as glass. Accordingly, it is possible to realize a definite pole piece length to permit an improvement in short-wavelength reproduction characteristics.
