IPC: B41J2/135
Filed: 1997-01-27
Abstract: PROBLEM TO BE SOLVED: To provide a groove forming method for suppressing the rise of a center part at the base of a groove for forming the wide groove for 200 microns or more on a monocrystal silicon substrate whose crystal face bearing is 110 through the use of potassium hydroxide aqueous solution.

Title: Method for semiconductor thin film
Inventor: SUKEGAWA OSAMU
IPC: G09F9/35
Filed: 1986-01-23
Abstract: PURPOSE:To inhibit problems, such as the deterioration in electrical characteristics due to the mixing of impurities, the lowering of the controllability of an etching process, etc., by forming an insulator layer on a transparent conductive film, shaping a contact hole in the insulator layer and forming a semiconductor thin film onto the insulator layer. CONSTITUTION:An insulating film 2 is formed onto a transparent conductive film 1. A contact hole 3 is bored to the insulating film 2 in drain and source electrode sections for a TFT, and an n<+>-a-Si layer 4 is laminated onto the insulating film 2, and brought into contact electrically with the transparent conductive film 1 in the contact hole 3 section. The contact holes are shaped only at the positions of shaped parts as the drain and source electrode sections for the TFT in a drain wiring section 9 and a source wiring section. Since the contact holes are bored where required for electrical contacts and a semicon ductor film is shaped, the area of the transparent conductive film exposed to plasma at the formation of the semiconductor film is inhibited at the irreduc ible minimum of a demand, thus reducing the quantities of impurities (IN, Sn, etc.,) taken into the semiconductor film.

Abstract: PURPOSE:To precisely align bump electrodes on a semiconductor element for electrode terminals on a mounting board even if deformation like cutout exists in the semiconductor element, and perform mounting, by installing an anisotropic conducting film and an electric resistance measuring means. CONSTITUTION:Bump electrodes 2 are formed on the surface of a semiconductor element 1. On the surface of a mounting substrate 3, electrode terminals 5 to be connected with the electrodes 2 are formed so as to correspond with the electrodes 2. A measuring means constituted of a DC power supply 6 and an ammeter 7 as a means to measure electric resistance between the electrode 2 and the terminal 5 is connected in series with the electrode 2 and the terminal 5. An anisotropic conducting film 8 is sandwiched by the electrodes 2 and the terminals 5. The electric resistance is measured by applying a current between the electrodes 2 and the terminals 5. The element 1 is relatively moved so as to minimize the value of electric resistance between the measured terminal 2 and electrode 5, thereby obtaining accurate alignment of the electrode 2 and the terminal 5. Hence the electrodes 2 are precisely aligned for the terminals 5 and mounting is enabled, even if deformation like cutout exists in the element 1.

Title: Radiation thermometer and temperature measuring method
Inventor: MARUI TOMOTAKA
IPC: G01J5/00
Filed: 1993-02-01
Abstract: PURPOSE:To measure the temperature of an object to be measured from the bottom side under such a bad condition as the hot rolling process where scattered objects exist by providing optical fibers, temperature measuring section, and fiber passing tube, etc. CONSTITUTION:By feeding water into a fiber passing tube 20, scales, etc., are washed away from the tube 20 before a steel plate is carried in. When a hot ingot detector 95 detects the steel plate, the tube 20 is drained of water and air is supplied to the tube 20. Because of the air, an optical fiber 80 floats in the tube 20 and the lower-surface temperature of the steel plate is measured while the steel plate passes over the tube 20. During the temperature measurement, the fiber 80 is cooled and protected from falling scales, etc., by the air flow. In addition, since the fiber 80 floats on the air flow, the fiber 80 becomes flexible and is not damaged by an air cushion effect even when scales, etc., collide with the fiber 80. When the steel plate passes over the tube 20, water is again supplied to the tube 20.
