摘要： The second harmonic wave of a solid laser light which is emitted from a second harmonic wave light source is divided into a plurality of laser beams by a diffraction grating. The divided laser beams are converged on a record carrier into a plurality of light spots by an optical head. Magnetic field generating coils for applying magnetic fields to the respective light spots in accordance with the recording signals from a signal line are disposed under the record carrier. Part of the solid laser light is reflected and input to a beam splitter. Since part of the light input to the beam splitter is taken out, a stabilizer controls the output of the solid laser light from the second harmonic wave light source, parallel recording/reproduction using the plurality of light spots which are arranged on the record carrier is enabled and the formation of the plurality of light spots is effectively controlled. Thus, a magneto-optical recording and reproducing apparatus which is capable of high-density recording and high-speed data transfer, which supplies a stable and accurate optical output, and which facilitates the control of the optical output is provided.

摘要： On the surface of a semiconductor substrate there are formed a silicon oxide film, silicon nitride film and resist, whereby a groove is formed in the semiconductor substrate through an opening portion by chemical dry etching. An oxide film is formed on the inner surface of the groove by wet oxidation and, further, this oxide film is removed by wet etching, after which the surface of the semiconductor substrate located on the outer-peripheral side of the groove from an angular portion defined between a side surface of the groove and the surface of the semiconductor substrate is exposed. Then, the inner surface of the groove and the exposed surface of the semiconductor substrate are oxidized to thereby form a LOCOS oxide film, and thereafter this LOCOS oxide film is removed. As a result of this, the angular portion is made round, thereby enabling the avoidance of the concentration of an electric field on the angular portion of the groove.

摘要： In a method of manufacturing a semiconductor device, after performing ion-implantation and before forming an oxide film, a silicon substrate is disposed within a furnace to undergo a heat treatment at a temperature equal to or higher than 950° C. for a specific time period (equal to or longer than 15 minutes). When performing the heat treatment and when raising a temperature up to the heat treatment temperature, oxygen is supplied together with nitrogen gas (inert gas). A supply amount of oxygen is controlled to be equal to or less than 5% when raising the temperature up to the heat treatment temperature, and to be equal to or less than 2% when performing the heat treatment. After the heat treatment, the oxidation film is formed. As a result, crystal defects (OSFs) are prevented from being produced on the silicon substrate surface.

摘要： A surface of a non-magnetic base plate is first coarsened to a required surface roughness and an ultrasonic vibration is then applied to the surface of the non-magnetic base plate while the nonmagnetic base plate is immersed in a liquid. Thereafter, a magnetic recording layer and a protective layer are successively formed on the surface of the non-magnetic base plate thereby to produce a magnetic recording medium. It is preferable that the frequency of a ultrasonic is within a range from 200 kHz to 1600 kHz. Surface fractional properties of the magnetic recording medium can adequately be controlled without variation of floatation height of a magnetic head during its running by varying an ultrasonic oscillation output and an ultrasonic processing time.

摘要： An optical head device includes a tilt servo mechanism using photodetectors for detecting rays of light reflected from the recording surface of an optical disk. The rays of light are obtained from a laser diode used as a light source for information reproduction. According to one aspect; prisms are formed on the flange of a converging lens to refract peripheral portions of the light emitted from the laser diode for tilt detection. According to another aspect, secondary diffraction grating domains at the sides of the primary diffraction domain of a diffraction grating diffract peripheral portions of the emitted rays of light for tilt detection. According to another aspect, a mirror reflects peripheral portions of the emitted rays from the laser diode. According to a further aspect a mirror reflects the light from the laser diode passing through a beam splitter. Each photodetector receiving the light reflected from the recording surface of the disk may be partitioned into two detector cells, and a tilt signal is obtained as the differential output of the two cells.

摘要： As a basic managing pattern, each manufacturing lot containing at least one workpiece is designated as a main objective to be managed. An appropriate number of similar type manufacturing lots containing workpieces having the same work conditions in at least one work step are loaded on a carrier. Then, the carrier is transported to a batch apparatus that performs simultaneous processing or machining operation applied to the workpieces or to an apparatus that brings the workpieces into an in-process work step under the same conditions, so as to cause the workpieces contained in respective similar type manufacturing lots to pass along a plurality of manufacturing process flows. Alternatively, an appropriate number of different type manufacturing lots containing workpieces having different work conditions are loaded on a carrier. Then, the carrier is transported to an apparatus that is capable of simultaneously bringing the workpieces into in-process work steps of different conditions, so as to cause the workpieces contained in respective different type manufacturing lots to pass along a plurality of manufacturing process flows.
