Title: Wiring method for semiconductor device
Inventor: IWAMORI TOSHIMICHI
IPC: H01L21/3205
Filed: 1989-06-15
Abstract: PURPOSE:To reduce reaction product of adding metal with etching gas by forming resist films responsive to a wiring pattern on an aluminum alloy film in which the metal is uniformly diffused in a heating step. CONSTITUTION:An aluminum alloy film 3 composed of aluminum and adding metal is heated to uniformly diffuse the metal on a substrate 1 on which semiconductor element groups are formed, and resist films 4 responsive to a wiring pattern is formed on the film 3. The film 3 exposed from the films 4 is removed by reactive ion etching. That is, the metal is uniformly diffused in the film 3 in a heating step, and irregular presence of the metal is eliminated in the film 3. Thus, reaction product of the metal with etching gas to be generated in case of the reactive ion etching can be reduced, and the irregular presence of the generated positions can be obviated as well.

IPC: F27B17/00
Filed: 1989-06-14
Abstract: PURPOSE:To produce optimum calorific power at both the times of vacuum heating and high pressure heating and to enable miniaturization of a facility by generating the heat of an ordinary heater alone when the inside of a furnace is made vacuum or low pressure to heat a material to be heated, and generating the heat of the ordinary heater and an auxiliary heater when the inside of the furnace is made high pressure to heat. CONSTITUTION:A control means is allowed to generate the heat of an ordinary heater 5a alone when a detected value of a pressure sensor 7 is vacuum or low pressure, and the heat of an auxiliary heater 5b too is generated to regulate the applied voltages of the heaters 5a, 5b if necessary so as to control so that the detected values of temperature sensors 6a, 6b may be same when the detected value of the pressure sensor 7 becomes a specified high value, namely, the pressure of the inside of the furnace is in a high pressure condition. Even at the time of high pressure heating, a difference between upper and lower temperatures of the inside of the furnace is corrected to uniform a temperature distribution. At this time, due to the high applied voltage of the auxiliary heater 5b a current value flowing in the heater for generating same output lessens, so that facilities such as a transformer, a cable and an electricity supply part attached to the heaters can be miniaturized.

IPC: H04N7/167
Filed: 1986-06-27
Abstract: PURPOSE:To improve the writing efficiency of data by writing drawn data in al addresses of one picture element in one data writing cycle. CONSTITUTION:Address data for writing drawn data in an image memory 111 are outputted from a microprocessor 12.

Filed: 1987-06-17
Abstract: PURPOSE:To prevent trouble detection due to erroneous recognition to improve the reliability and the precision of a monitor control function by regarding general data, which is transmitted and received between a destination processor and a main processor, as a part of health check control data to perform the control. CONSTITUTION:A data transfer control means 2 and a dummy health check control data generating means 3 are provided, and the means 2 requests a communication control means 1 to transmit and receive general data and detects completion of transmission and reception of general data, and the means 3 generates dummy health check control data corresponding to health check control data received from a destination processor 6 in accordance with the detection output of the means 2. A health check monitor control means 4 generates dummy health check control data corresponding to a prescribed pattern to update a monitor timer 5 once more if the response to health check is not obtained in a prescribed time. Thus, since the destination processor is not immediately decided to be abnormal when health check control data is not received, trouble detection due to erroneous recognition is reduced to improve the reliability of the monitor function.

Abstract: PURPOSE: To improve precision by providing part of a magnetic body piercing through a fixed coil with a combined function of generating a synchronous signal and comparing an electromotive force and the phase of a synchronous signal.  
     CONSTITUTION: A magnetic body 2 is turned axially, piercing through a coil 4. This magnetic body 2 has a wing part 15, 16 and has the passage of terrestrial magnetism converted from horizontal to vertical component and periodically changed in magnitude and direction. Consequently, in the coil 4, an AC electromotive force (a) of the same period as the rotation of an axis 1 generates. Next, two photoelectric switches 9 are provided being deviated 90° from each other centering around a rotary axis 1. On one of the rotary axis 1, a semicircular optical shutter 7 is fixed. Under this arrangement, rectangular waves (b), (c) having a phase deviated 90° are output. Thanks to this constitution, (a) of signals, (a), (b), (c) has a change in the phase on account of the direction of a horizontal component of terrestrial magnetism, although the (b) and (c) have nothing to do with the direction of terrestrial magnetism. Thus it is possible to enhance precision by comparing the phase of (a) with (b), (c).
