Title: Semiconductor device
Inventor: ISOBE AKIRA
IPC: H01L21/312
Filed: 1987-03-16
Abstract: PURPOSE:To obtain a highly reliable semiconductor device by a method wherein the carbon content down to a prescribed depth from the film surface of an organic siloxane polymer film of an interlayer insulating film is set at a value which is smaller than half the content at a part deeper than the prescribed depth so that the close adhesion to an upper layer inorganic insulating film and a metal film is enhance and that the deterioration of the film quality and the occurrence of a crack are prevented. CONSTITUTION:At a semiconductor device whose interlayer insulating film for a multilayer interconnection part is constituted by an organic siloxane polymer film or by a multilayered structure composed of the organic siloxane polymer film and other inorganic insulating films, the carbon content at a part 5 down to a prescribed depth from the film surface of the organic siloxane polymer film is set at a value which is smaller than half the content at a part 4 deeper than the prescribed depth. For example, after an Al wiring part 3 has been formed on an insulating film 2 on a semiconductor substrate 1, an organic siloxane-related polymer solution is coated on the whole surface; after the assembly has been baked, an organic siloxane polymer film 4 is formed. Then, if the assembly is heat-treated in an O2 plasma of a pressure of less than 0.1 Torr at 450 deg.C for 60 sec, the carbon concentration is reduced down to a depth of about 1000 Angstrom  from the film surface; a low carbon-content layer 5 whose carbon concentration is reduced to about 20% of an initial value is formed.

Title: Tall arc furnace
Inventor: TAKIMOTO HIDEKI
IPC: F27D13/00
Filed: 1995-02-24
Abstract: PURPOSE: To enhance the heat arriving efficiency of an arc to scrap in a melting period, and to raise the heat arriving efficiency from the gas generated from an arc furnace to the scrap by providing the specific relation between the height of the upper end of the sidewall in the furnace from the molten metal level in the furnace and the diameter in the furnace. CONSTITUTION: The body 1 of an arc furnace is formed of a furnace tube 2 and a body raising part 3, and the relationship between the height L from the molten metal level in the furnace to the upper end of the inner wall of the furnace and the inner diameter D of the furnace satisfies an equation L/D=0.6 to 1.4. In this case, the larger the L/D becomes, the less the heat loss ratio of exhaust gas decreases. If the L/D exceeds 1.4, the decreasing amount is small and substantially saturated. On the other hand, if the L/D exceeds 1.4, the demerit in which the data of the facility must be increased occurs. Thus, the heat arriving efficiency from the arc and the gas generated in the furnace to the scrap in the melting period can be enhanced. Thus, the operability is excellent, and the operation cost can be reduced.

Filed: 1987-03-17
Abstract: PURPOSE:To improve stability with age by laminating a conductive metal layer, halide layer of the conductive metal, carbonic acid ion selective layer and buffer layer on a base, thereby forming an ion selective electrode. CONSTITUTION:The conductive metal layer 2 consisting of silver, nickel, gold, etc., is laminated on the electrically insulating base 1 and the halide layer 3 of the conductive metal is laminated thereon. The carbonic acid ion selective layer 4 is laminated thereon. The selective layer 4 is formed by incorporating an ion carrier such as 4-alkyl-alpha,alpha,alpha-trifluoroacetophenone into a polymer binder. The buffer layer 5 is further laminated thereon. The buffer layer 5 is formed by incorporating a pH buffer agent into a hydrophilic polymer binder. Since the buffer layer having sufficient buffer capacity is provided to the electrode, the undesirable influence by disturbing materials such as salicylate and P- aminosalicylate is decreased and measurement errors are eliminated. In addition, the stability with age is improved.
