Title: Manufacture of semiconductor device
Inventor: SANNOMIYA ITSURO
IPC: H01L21/302
Filed: 1990-11-13
Abstract: PURPOSE:To prevent a pattern of an upper positive resist layer from skipping when developing the upper positive resist layer by forming a coating-agent film which functions as an adhesion layer between lower pnd upper positive resist masks. CONSTITUTION:A coating agent such as polyvinyl alcohol which is soluble in a developing liquid and rinsing liquid for a second positive resist layer is so applied as to cover a lower positive resist mask 5a for forming a coating- agent film 8 which would function as an adhesion layer. Nextly, positive resist is applied onto the coating-agent film 8 to form an upper positive resist layer 9, which would be patterned by exposure to light and wet development to form an upper positive resist mask 9a for forming a pattern of a polysilicon film 3. As a result, a better adhesion is obtained between the upper positive resist layer 9 and the lower positive resist layer 5 and thus a pattern skip of the upper positive resist layer 9 is avoided when developing the upper positive resist layer 9.

Title: Pseudo grounding circuit of audio power amplifier
Inventor: KONISHI KOJI
IPC: H03F3/68
Filed: 1999-09-24
Abstract: PROBLEM TO BE SOLVED: To obtain a circuit constituting an efficient audio DC connecting power amplifier by a single power source. SOLUTION: The terminal of a speaker which ordinarily has to be connected to the ground has to always keep reference voltage with respect to a terminal to which an audio signal current is made to flow. That is because a speaker can be driven faithfully to a signal only when stable voltage is kept with respect to an audio signal making an intensive voltage variation and impedance is sufficiently low with respect to a load. In order to realize a DC connection power amplifier by a single power source, it has to be executed by voltage at the midpoint of power source voltage. Then, a push-pull semiconductor power amplifier is connected by low impedance outputting a midpoint potential instead of the ground.

Filed: 1988-12-05
Abstract: PURPOSE:To reduce the turbulence of the heat distribution in wafer surface by a method wherein a wafer holder is previously arranged on the inner peripheral bottom surface of a process tube while semiconductor wafers in the heated state at high temperature are inserted into the process tube from an opening thereof to be loaded on the process tube. CONSTITUTION:A wafer holder 5 is composed of a protrusion 4 made of a quartz bar with multiple grooves 6 formed on the inner peripheral bottom surface thereof inside a process tube 1. Semiconductor wafers W parallel-arranged on a holding boat outside the tube 1 are collectively held by a handler 2 and then loaded on the holder 5 inside the tube 1. When the handler 2 is pulled out of the tube 1, the opening 8 of the tube 1 is blocked by an end cap 9 and then the wafers W are processed. At this time, since no part in large thermal capacity exists in the tube 1 at all, the turbulence of the heat distribution in the tube 1 is minimized. Accordingly, the turbulence of the heat distribution in the wafer surface can be reduced.

IPC: G06F1/16
Filed: 1995-11-02
Abstract: PROBLEM TO BE SOLVED: To suppress the rotation of a display case to be rotated in lateral and longitudinal states except its opened state >=90 deg.. SOLUTION: The display case 15 is rotatably fitted to a supporting member 14 fixed to a device body 11 so as to be opened/closed. When the opened angle of the member 14 is less than 90 deg., an engaging pin 36 is penetrated into a through hole 37 formed on the member 14, positioned in an engaging hole 38 formed on the case 15, suppressing the rotating operation of the case 15.

Abstract: PROBLEM TO BE SOLVED: To limit a current flowing in the base section to a ridge area by specifying a width of a first semiconductor section and providing a diffraction grating formed by a triangular grove having the side surface of 111A crystal surface to at least a part of the first semiconductor section along the upper surface thereof so that it is located on an active layer. SOLUTION: A GaInAsP layer 5 is formed on a GaInAsP layer (active layer) 4, and a resist mask irradiated with electron beams is used to etch the GaInAsP layer 5 to form a wavy layer, which is used as the distributed feedback lattice. Since this etching is anisotropic etching, the etching rate for the 111A surface is very small and a triangular groove forming the 111A crystal surface as the side surface may be formed. A current flowing in the base area can be limited only to the ridge area by providing a dielectric material layer to the surface of the swelled semiconductor layer (reinforcing section) isolated by the groove from the ridge waveguides 7" and 8".
