Title: Semiconductor device
Inventor: TSUDA HIROSHI
IPC: H01L29/417
Filed: 1985-03-12
Abstract: PURPOSE:To reduce capacitance across the emitter-base and across the base- collector and to prevent the short circuit across the emitter and base electrodes, by forming insulating films on the electrodes separated by an inverted trapezoidal polysilicon layer 4. CONSTITUTION:A trapezoidal polysilicon layer 4 is formed to define an emitter region 9. At this time, the polysilicon layer 4 extending over an oxide film 2 is reduced to such an extent that a contact hole can be formed. Patterning of photoresists is done along the opening ends of the oxide film 2 for forming a base region 3 and ends of the polysilicon layer 4, so that base and emitter electrodes 6, 5 separated securely by the polysilicon layer 4 can be formed. Next, after an insulating film 12 is formed on the entire face, contact holes are formed over the emitter electrode 5 and base electrode 6 and connecting electrodes 13, 14 are formed. In this way, since there exist two insulating films 2, 12 under the connecting electrodes 13, 14, the capacitance can be reduced and the short circuit across the base and emitter electrodes 6, 5 can be prevented.

Filed: 1991-02-21
Abstract: PURPOSE:To enhance the transmission efficiency and the resolution without the material of an electrode being changed, by applying pulse voltages to anode and cathode electrodes so that their application periods are overlapped with each other by a substantially half thereof. CONSTITUTION:Anode electrodes A1 through AL and cathode electrodes C1 through CL are arranged alternately, and are applied thereto with time-sheared pulse voltages, successively. At this time, for example, the timing of application of time-sheared pulse voltages to the anode electrodes A1 through AL is shifted (delayed) from the timing of application of time-sheared pulse voltages to the cathode electrodes C1 through CL by one half of the application period of the time-sheared pulse voltages. That is, for example, the period during which the time-sheared pulses are applied to the anode electrodes, are overlapped with the period during which the time-sheared pulse voltages are applied to the cathode electrodes adjacent to the anode electrodes on both sides of the latter by one half of the period. Accordingly, electric discharges are carried out successively between two adjacent electrodes, thereby it is possible to produce discharged plasma.

Title: Highly accurate laser measurement method and apparatus for surface of solid
Inventor: MATSUMOTO KOICHI
IPC: G01B11/24
Filed: 1989-03-01
Abstract: PURPOSE:To measure a geometric shape of a surface of an object precisely by dividing a laser light used as light source in two to irradiate a surface of an object to be measured with one laser light while a reference mirror is irradiated with the other laser light as reference light. CONSTITUTION:Incident light 1 (frequencies: f1 and f2) is incident into a polarization prism 3 to be separated via a beam splitter 2 and one probe light 10 goes to a surface 8 of a solid while the other light as reference light 9 to a reference mirror 7. Reflected light thereof interferes with each other after passing through a polarizer 13 via a reflection mirror 6 to measure. In this case, a beat signal by the frequencies f1 and f2 is formed and a phase of the beat signal varies according to a shape of the surface thereof to measure an optical shape with high resolutions. The other probe light 10 is detected individually with a polarizer 12 as light wave irradiating the surface 8 alone and deviated from the position of a focus of a lens 5. Thus, a signal of a displacement is obtained utilizing the resulting change in an image pattern and incident into an actuator 4 thereby controlling a distance between the surface 8 and the lens 5 constantly.

Abstract: PURPOSE:To prevent a light emitting means from careless damaging and to prevent fast deterioration by detecting the quantity of light from the light emitting means, and displaying the abnormality when the detecting level exceeds a prescribed value. CONSTITUTION:The invented optical recording device modulates laser light projected from a semiconductor laser 1 by switching laser injection current I in accordance with a video signal supplied to a terminal 5 by a laser driving circuit 4. A photodetecting element 2 receives the laser light, detects the output level, and when the detected signal reaches a reference voltage VREF previously set up to a level value obtained when the limited quantity of light is made incident to the photodetecting element 2, an output is obtained from a comparator 8.
