Title: Flattening of semiconductor substrate
Inventor: FUKUYAMA SHUNICHI
IPC: H01L21/312
Filed: 1988-05-31
Abstract: PURPOSE:To prevent diffusion of P atom from a phosphor transformation silicon layer used for flattening and to increase production yield as well as reliability by performing spin coating of phosphorus modified silicone resin on an oxide thin film and then flattening it after forming the oxide thin film on a substrate to be treated. CONSTITUTION:After forming an oxide thin film on a substrate to be treated as a method for flattening the stage difference produced on a semiconductor substrate to be treated by an insulation layer, a phosphorus modified silicone resin is spin-coated on the oxide thin film by spin coating and is flattened. The phosphorus modified silicone resin in a structure as shown in Figure is obtained by allowing, for example, methyltrimethoxysilane or tetramethoxysilane to hydrolysis and condensation polymerization, and by converting a hydroxyl group of the resulting low molecular polymer into phosphoric ester with chlorophosphoric acid. Then, after forming SiOx on Si water wherein surface stage difference has been produced by the CVD method, phosphorus modified silicon resin liquid dissolved in methylisobutyl ketone is spin-coated on it to allow 1mum thick phosphorus modified silicone resin layer to be formed.

Abstract: PURPOSE:To relieve electrostatic focusing at end portions of pn junctions without forming a guard ring area in a planar type APD and achieve sufficient doubling effects at a light receiving area by causing a doubling layer to be carried out according to a graded system where impurity density decreases from a substrate side to a surface side. CONSTITUTION:A doubling layer 13 where one conductivity type impurities are distributed so that density decreases from a substrate side 1 to a surface side and areas for forming junctions 14 formed by introducing optionally the opposite conductivity type impurities into the doubling layer 13 are provided. For instance, the following layers and area such as: n-type InGaAs optical absorption layer 2, n-type InGaAsP layer 3, n-type InP doubling layer 13 with graded impurity density as well as p-type InP area for forming junctions 14 which is formed by diffusing Cd are formed on the n-type InP substrate 1. In such a case, end portions 14A of area for forming junctions 14 become gentle due to circumstances where impurity density in the n-type InP doubling layer 13 is in a graded state in a width direction. Thus, the end portions are free from electrostatic focusing.

IPC: H01H33/91
Filed: 1988-06-02
Abstract: PURPOSE:To obtain high breaking performance with small drive energy and size by communicating a hollow part of operation rod of buffer cylinder with a buffer chamber upon the initial stage of operation while communicating with a container through a hole at the hollow part upon the later stage thereof. CONSTITUTION:Though an arc 13 generates much heat at the initial stage of operation, a nozzle 10 is not sufficiently opened, and therefore there is not opening ability. A hole 5a of control rod 5 and a hole 14a of breaking cylinder 14 extend from the position of an end 7a, and a hollow part 5b is communicated with a buffer chamber 11. A swelling flow from the arc 13 passes through the part 5b to turns into a flow 12b to flow in the buffer chamber 11 sharply, resulting in increase in the pressure inside the chamber 11. The holes 5a, 14a pass through the end 7a to communicate with the circumference. The hollow part 5b is released with a circumferential gas part and heat is discharged from the arc. High pressure increase is maintained in a cylinder 6 and a high speed gas flow 12a is applied with the arc, thereby high breaking performance is obtained.

Filed: 1999-05-14
Abstract: PROBLEM TO BE SOLVED: To obtain an SOI substrate without increasing the number of production processes without increasing the cost of materials and without lowering the production yield, by a method wherein an oxide film is formed in the interface between a silicon substrate and an epitaxial layer, and the maximum oxygen concentration of the oxygen film is set at a specific range. SOLUTION: A thin oxide layer 2 is formed on a single-crystal silicon substrate 1. After that, the single-crystal silicon substrate 1 is introduced into an LPCVD furnace. While SiH4 is used as a source gas, an amorphous silicon layer 3 is deposited at a deposition temperature of 550 deg.C and under a pressure of 0.3 Torr. After that, the single-crystal silicon substrate 1 is taken out once from the LPCVD furnace. A heat treatment is executed for three hours at 700 deg.C in an ambient pressure nitrogen atmosphere. The amorphous silicon layer is crystallized, and an epitaxial silicon layer is formed. At this time, the maximum oxygen concentration of the oxide layer 2 in the interface between the epitaxial silicon layer and the silicon substrate 1 is set at a range of 2×1014 cm-2 to 8×1014 cm-2.

Abstract: PURPOSE:To provide a large-capacity flywheel in the case where dimensional restrictions such as transportional limits are exist by a constitution wherein rotary bodies, which have sector-shaped projections on the periphery of a disc, are overlapped opposedly with an angular deviation to form a disc. CONSTITUTION:For example, parts 2 and 2' are overlapped opposedly with an angular deviation of 90 deg. and integrated together by fasteners 3 to form a disc-shaped flywheel. The part 2 comprises sector-shaped projections 2a formed at diametrically opposed positions on the periphery of a disc having a diameter L and a thickness h, and is formed with fastener holes 4. The part 2' is in the same form as the part 2. This results in that a large-capacity flywheel which have not conventionally been obtained can be formed by setting the width of the disc and of the projections within transporational limits when the latter exist. When the energy to be accumulated is constant, the weight of the flywheel can be reduced, so that an economical flywheel can be obtained.

Title: Gear noise reducing apparatus
Inventor: ENDOU MAKOTO
IPC: F16F15/14
Filed: 1982-07-30
Abstract: PURPOSE:To remove backlash of gears and to reduce the gear noises, by imparting a subsidiary gear with a force for driving the same in the opposite direction by use of the centrifugal force of a flyweight fixed to a main gear, and thereby causing phase shifting between the teeth of the above two gears. CONSTITUTION:When a main gear 1 is turned in a counterclockwise direction, a subsidiary gear 3 is turned in the same direction as the main gear 1 since it is urged onto the end face of the main gear 1 by a resilient metal stopper 13 and held in mesh with a mating gear 4. On the other hand, a flyweight 6 is pivoted at one end thereof by a pin 5 fixed to the main gear 1 and the other end of the flyweight 6 is set free, so that the flyweight 6 is forced to turn in a clockwise direction around the pin 5. By this force of the flyweight 6, a roller 8 urges the side face 32A of a hole through which the subsidiary gear 3 is extended in a clockwise direction. Resultantly, the phase of the teeth 31 of the subsidiary gear 3 is delayed relatively to that of the teeth of the main gear 1, so that phase shifting is caused between these two gears 1 and 3.
