IPC: B05D1/40
Filed: 1989-04-27
Abstract: PURPOSE:To improve the efficiency of the process and the yield by attaching viscous materials on the rugged surface of a substrate to be worked and applying perpendicular centrifugal force to the surface of the substrate to be worked, thereby applying the materials by a spin coating. CONSTITUTION:The semiconductor substrate 1 to be worked has projecting parts 2 and recesses 3. The viscous materials 4, 5 are formed by depositing a photoresist to be used in the process for production of ordinary semiconductor elements by a spin coating or electrostatic coating and vapor deposition method, then subjecting the semiconductor substrate 1 to be worked to a weighing treatment by a high-speed centrifugal weighting device. The centrifugal force is applied by rotating the substrate semiconductor around one point in the direction perpendicular to the surface of the substrate. The easy inflow of the viscous materials into the recesses is attained by applying a centrifugal force of several hundred times the gravity. The working efficiency and the yield are improved in this way.

Title: Solid-state image pickup device
Inventor: YOKOGAWA HIROSHI
IPC: H04N5/335
Filed: 1981-07-14
Abstract: PURPOSE:To prevent a relative position between an image pickup element output signal and a sampling pulse signal from being changed due to a change in ambient temperature, by supplying the sampling pulse signal to a sampling circuit via a buffer amplifier. CONSTITUTION:Since driving pulse signals phi1, phi2 and phi3 drive a capacitive load in high speed, the signals are applied to an image pickup element 15 via three stages of buffer amplifiers 121-123, 131-133 and 141-143. A sampling pulse signal is applied from a driving pulse generator 11 and applied to a sampling circuit 17 via buffer amplifiers 211, 212 and 213 having the same number of stages as the buffer amplifiers. Thus, even if an ambient temperature is fluctuated, since the phase of an output signal of the element 15 and of the sampling pulse signal changes for the same amount, the relation of phase of the both is kept constant.

Abstract: PURPOSE: The heat blow of the drying bag passes through the space formed by the mattress and the drying bag body, and through the part consisting in the flow pathway in which the air passes inside the mattress. By doing so, the mositure of the mattress is absorbed and the bag body is connected to the suction side of the heat blower. Thus, high drying effeciency for the mattress is attained.  
     CONSTITUTION: A tube 10, possessed of one or more than one opening 12 in the tube wall, is attached at least in one side of a drying bag 14 through a fixing band 16.

Abstract: PURPOSE: To decrease the themal stress of a nozzle box by installing a heat shielding  plate which covers the outside of the nozzle box, on the outside wall of the nozzle box, keeping a gap between the outside wall surface.  
     CONSTITUTION: The nozzle inlet steam flow 2 flows into rotor blades 11a and 11b through nozzles 3a and 3b in the opposite directions, and the rotor blade steam flow 5b having flowed down on the rotor blade 11b in one step forms inverted flow, and joins with leaked steam flow 8b to form steam chamber outside wall steam flow 9b, and said flow is changed to the steam in low temperature in high flow speed and flows along the nozzle box outside walls 4a and 4b to the low pressure side. As a heat shielding plate 16 is arranged on the nozzle box outside walls 4a and 4b, the nozzle box 4 is heat-insulated without being cooled by steam flow 9b. Leaked steam flow 8a flows into a desk pace 20 to form steam chamber outside wall steam flow 9a but the nozzle box 4 is protected by the heat-shielding plate 16. Thus, the temperature difference between the inside and outside walls of the nozzle box 4 can be reduced, and also the thermal stress can be reduced

Title: Manufacture of semiconductor wafer
Inventor: HAJIME TAKAFUMI
IPC: H01L21/304
Filed: 1995-03-29
Abstract: PURPOSE: To eliminate a surface sag in a mirror working to increase more the flatness of the surface of a wafer by a method wherein before a process for mirror-processing, the surface or the surface and rear of the wafer is/are gradually processed into a wall thickness form from the central part of the wafer toward the peripheral edge parts of the wafer. CONSTITUTION: Working strains 1a are respectively generated on both surfaces of a lapped wafer 1 and a double-side polishing is performed for removing these work strains 1a. At this time, as the peripheral edge parts of the wafer are formed into a wall thickness compared with the thickness of the central part of the wafer, both surfaces of the wafer are polished in the so-called boring recessed state. That is, there is a setpoint for polishing both of the surface and rear of the wafer equally and in a flat state in the double-side polishing and by increasing more the number of rotation of upper and lower surface plates than this setpoint, the temperature in the polishing surfaces is made to rise and both surfaces of the wafer are polished in the boring recessed state.  When a finish polishing is performed on the surface of this wafer 1, a boring recessed thickness (t) is offset with a surface sag thickness, which ought to be generated in this process, and the surface performed the finish polishing is flatly mirror-worked. It is also possible that the rear of the wafer is also performed the finish polishing and the wafer is formed into a wafer with the flatly mirror-worked surface and rear.

Title: Ic package
Inventor: NAKAMURA TOMOHARU
IPC: H01L21/60
Filed: 1986-05-14
Abstract: PURPOSE:To avoid a shortcircuit defect of bonding wirings in an IC package by connecting the bonding pad of an IC chip with an IC lead terminal by using the wirings coated with insulator. CONSTITUTION:An IC chip 3 is thermally press-bonding onto the IC chip substrate 1 of an IC lead frame, and the bonding wirings of the chip 3 is connected with an IC lead terminal 2 by means of bonding wirings 4 covered with insulating films 6. The film 6 is covered around the wirings 4 made of aluminum or the like by means of plating or coating. If the insulating film is excessively thick, the film 6 affects adverse influence to the connection of bonding. It is accordingly necessary to sufficiently reduce the thickness of the film. Resin is eventually fed to the chip 3 and the whole IC lead frame, and molded to complete an IC. Thus, even if the bonding wirings are contacted with the edge of the chip, the wirings are not shortcircuited, since the wirings 4 are covered with the insulator, thereby extremely reducing the possibility of generating defects.
