Title: Chemical vapor deposition device
Inventor: IMATSUDO MAHAUIRI
IPC: H01L21/205
Filed: 1990-07-27
Abstract: PURPOSE: To enhance uniformity of deposition by introducing a reaction substance gas into a chamber, regulating a plurality of exhaust ports arranged at an interval while communicating with the chamber through individual valve mechanisms and generating a selected fluid vector pattern of the reaction substance gas contiguously to a substrate in the chamber. CONSTITUTION: A reaction substance gas is fed from some orifice 32A-50A into a chamber 24 and exhaustion control valves 46, 52 are operated continuously to generate a selected pattern of local fluid vector of the reaction substance gas contiguously to a substrate 22 in the chamber. When a central exhaust passage 48 is opened/closed and an outer circumferential exhaust passage 42 is opened/closed continuously, for example, a fluid pattern is generated clockwise or counterclockwise in the chamber. Similarly, a radial flow of the reaction substance is generated in the chamber 24 by opening the central exhaust passage 48 at first and closing one or more circumferential exhaust passage 42 and then reversing the state, i.e., opening the circumferential exhaust passage and closing the central exhaust passage.  According to the arrangement, uniformity of a coating on the substrate 22 can be enhanced.

Abstract: PURPOSE:To improve the monitoring accuracy and decrease the assembling cost by forming laser and photo diodes in one on a single chip. CONSTITUTION:An n-type Si substrate 6 permits an n-type GaAs buffer layer 7, an n-type GaAlAs clad layer 8, a GaAs active layer 9 as well as a p-type GaAlAs clad layer 10 to carry out epitaxial growth in sequence on its substrate and layers 7-10 with the exception of a portion are removed by etching and then an electrode 11 is mounted at their remaining portions to form a laser diode. Once a p-type region 12 and an ohmic electrode 13 are formed at the exposed surface of the substrate 6, a pn junction is made between the n-type Si substrate 6 and respective layers and then the laser diode and a photo diode are formed in one on a chip. As a result, laser beams emitted out of the laser diode can be efficiently taken in the light-receiving surface of the photo diode and the above procedures serve the purpose of improving the light output monitoring system with high accuracy as well as of simplifying the process after carrying out assembling works and so on.

Title: Objective lens and method for measuring the lens
Inventor: MARUYAMA KOICHI
IPC: G01M11/02
Filed: 1991-05-02
Abstract: PURPOSE:To obtain an objective lens having a few measuring errors even in the case of using a light source whose wavelength at the time of measuring is different from at the time of actual use by making a spherical aberration occurring amount in plural wavelengths which are mutually different nearly equal. CONSTITUTION:Recording density is inversely proportional to the square of the spot diameter of a laser beam for writing, and the light spot diameter is proportional to the numerical aperture N.A and inversely proportional to the wavelength used. In order to improve the recording density, the objective lens is designed so that the numerical aperture N.A is large and the lens is used in an ultraviolet area. Meanwhile, at the production stage of the lens, measurement by using the light source in the ultraviolet area at the time of using is difficult, so that an He-Ne laser which outputs the visible light having coherence and is inexpensively is used. The spherical aberration is corrected to the wavelength 351nm of the light source at the time of using and the wavelength 633nm of the light source at the time of measurement. By making the change of the spherical aberration caused by the difference of the wavelength small, measurement is performed in a state where the spherical aberration is little and the performed of a lens is accurate.

Abstract: PURPOSE:To improve the speed of an encoder circuit with many bit numbers by providing a clock pulse source operating a driving means, and a clock control current source increasing the current flowing to a bit line synchronously with the clock pulse. CONSTITUTION:A clock control current source 8 is controlled so that it is set at the through-state to cause a current to flow, and it is reset at the latch state synchronously with a clock.
