Title: Manufacture of semiconductor device
Inventor: SUNADA TAKESHI
IPC: H01L21/3205
Filed: 1993-04-08
Abstract: PURPOSE:To prevent an increase in the diameter of the surface of the opening of a via hole and a shortage of the burying of a wiring in the via hole from being generated by a method wherein an opening part to reach the lower layer wiring is formed using a first resist mask, a second resist, with which the opening part is filled, is etched by a tapered reactive ion etching method and a tapered part is formed on the upper part of the sidewall of the opening part. CONSTITUTION:An opening part to reach a lower layer wiring 31 is vertically formed using a first resist mask 35a to correspond to a via hole. Then, a second resist 37 is anew applied without peeling a resist. Then, the resist 37 is etched back and the surface of the resist 37, buried in the opening part, is formed on the same surface as that of an interlayer insulating film 32. Then, while the first resist mask surface and the second resist surface, exposed in the opening part, are backed by a tapered reactive ion etching method, a tapered part is formed on the upper part of the via hole. An increase in the diameter of the surface of the upper opening of the via hole formed by this method is very little and as the via hole has the tapered part, a shortage of the burying of the Al wiring in the via hole is improved.

Abstract: PURPOSE:To prevent the freezing of an indoor heat exchanger without damaging a cooling action to an inverter circuit, by installing first and second outdoor fans to an outdoor unit, detecting the pressure or the temperature of refrigerant in an outdoor heat exchanger, operating only said first outdoor fan when a detected temperature is lower than a preset value, and operating said first and second fans when they reach the specified value. CONSTITUTION:During cooling operation, a control section 25 detects the difference between a detected temperature by a room temperature sensor 27 and a preset room temperature and controls an output frequency of an inverter circuit 7 in compliance with the differential temperature, that is, the operation frequency of a compressor 6. The control section 25 detects condensation pressure by a refrigerant pressure sensor 28, and halts the operation of an outdoor fan 12 and operate only an outdoor fan 11 when the condensation pressure drops below a specified release start pressure, which makes it possible to inhibits the condensation operation of an outdoor hear exchanger 5 and hence prevent the freezing of an indoor heat exchanger 22. On the other hand, the outdoor fan 11 near the inverter circuit 7, if it is continuously operated, can provide satisfactory cooling air to the inverter circuit, thereby extending the lifetime for electrical components.

IPC: C01G1/00
Filed: 1991-04-11
Abstract: PURPOSE:To produce a Bi-based oxide superconductor free from a coarse foreign phase and excellent in superconductivity such as Jc. CONSTITUTION:The raw material A consisting essentially of the multiple oxide of Bi2Sr2Ca1Cu2Ox phase ((2212) phase) and the raw material B consisting essentially of the multiple oxide of a Bi2Sr2Cu2Oy phase are mixed so that the mixture contains 10-90wt.% of the multiple oxide of the (2212) phase. The mixture is formed into a desired shape, and the formed body is heat-treated under specified conditions.

As a result, the formed body is sintered at a low temp. since the multiple oxide other than the (2212) phase is contained, the foreign phase is not coarsened, and the Jc is enhanced.

Abstract: PURPOSE:To shorten the time for producing vegetable powder and regulate the particle diameter of powder and amount of lipids without carrying out pretreatment by exposing a plant to an atmosphere of high-pressure carbon dioxide, reducing the pressure, pulverizing the plant, reincreasing the pressure and extracting the lipids. CONSTITUTION:A plant (e.g. almond) is exposed to an atmosphere of high- pressure carbon dioxide and the pressure in the above-mentioned atmosphere is then reduced at >=0.1kg/cm<2> per min rate to pulverize the plant.
