Title: Forming method of multilayer wiring
Inventor: YAMADA YOSHIAKI
IPC: H01L21/768
Filed: 1984-06-25
Abstract: PURPOSE:To form the multilayer wiring of a semiconductor integrated circuit characterized by excellent flatness and high reliability, by using a double-layer structure, in which a plasma nitride film is deposited and a sputtered oxide film is further etched thereon, as an insulating film between metal wirings. CONSTITUTION:A nitride film 204 is deposited on a first-layer aluminum wiring 203. A sputtered oxide film 205 is deposited thereon by applying a high-frequency bias on a semiconductor substrate. Thus the surface is flattened. Then the surface is coated by a photoresist film 206. A selective opening part is provided in the photoresist film 206. The silicon oxide film 105 on an interlayer insulating film is etched by buffered fluoric acid with the photoresist 206 as a mask. The etching is stopped at the upper part of the silicon nitride film because the etching speed of the lower silicon nitride film 204 is extremely slow. The silicon nitride film 204 is removed by anisotropic etching. An opening part 207 with depth reaching the first aluminum wiring layer 203 is provided. Then the photoresist film 206 is removed, and a second layer aluminum wiring layer 208 is provided. Finally heat treatment is performed.

Abstract: PURPOSE:To eliminate shortage of braking force when brake is applied by making it possible to supply the specified pressure which is lower than the pressure to be supplied when a selector valve is opened as control pressure for a pressure control valve when the selector valve which is opened or closed by operator is closed. CONSTITUTION:For example when load on vehicle is small and a selector valve 13 is changed over to the position communicating with atmospheric air by shutting off from an air reservoir 1, compressed air pressure to be supplied into a control chamber A of a pressure restriction valve 9 by a pressure reducing valve 15 is kept under the specified pressure lower than that of the air reservoir 1. A stepped piston 27 of the pressure restriction valve 9 is moved to an exhaust support 24 side due to the specified pressure, and a valve 33 makes input and output chambers C, B communicate irrespective of stepping on a brake pedal 5a. When brake starts to act, it is possible to increase pressure of a rear brake chamber 11 equally with pressure from a brake valve 5 which supplies pressure into the input chamber C of the pressure restriction valve 9 through a pipe passage 8. After that, it is possible to restrict increase rate to a lower rate than pressure of the brake valve 5 due to pressure reduction of the pressure restriction valve 9.

Title: Radio wave transmitter of rescue carrier wave intensity fluctuation system
Inventor: WATANABE KIYOICHI
IPC: H04B1/034
Filed: 1995-04-20
Abstract: PURPOSE: To estimate a transmission position with precision within several meters by synthesizing strong/weak signals as a transmission radio signal so as to transmit it. CONSTITUTION: A strong carrier wave and a weak carrier wave are periodically outputted. A sound wave 1 is loaded on the carrier wave 2 so as to transmit them. At the time of long distance search, only the part of the strong carrier wave is detected. When a receiver is adjusted in the direction of a rescuer, the sound wave which is outputted periodically flows. When the direction is deviated, the output of the sound wave is attenuated and it becomes a silent state. When the receiver is adjusted to the direction of a person searching a position at the time of short distance search, the sound wave continuously flows and only the part of the strong carrier wave is outputted.

Abstract: PURPOSE:To make the shapes of a left side diffraction grating and a right side diffraction grating uniform by providing a process in which a photoresist is developed and a cyclic pattern is formed and a process in which a semiconductor substrate is etched by using the photoresist with the cyclic pattern as an etching mask. CONSTITUTION:A photoresist is applied to an InP semiconductor substrate 1 and a dielectric film 3 is partially removed by normal mask exposure with a mercury lamp light. The photosensitivity of the dielectric film to the mercury lamp light is more than ten times higher than that of the photoresist. Therefore, the photoresist 2 is haldly exposed. The InP substrate 1 is inclined and subjected to interfrrence exposure by two HeCd laser beams applied with an incident angle of 54.8 deg. against a horizontal plane. After the dielectric film is dissolved and removed by a solution of DBS 1% and H2O2 5%, the photoresist is developed by an exclusive developing solution, dilluted to 1/3 density. The InP substrate 1 is etched by using the photoresist with a cyclic pattern as an etching mask and diffraction gratings 4 are obtained. With this constitution, the diffraction gratings of the same quality can be easily formed on both the regions A and B.
