Title: Manufacture of semiconductor device
Inventor: YANAGI TOSHIO
IPC: H01L21/318
Filed: 1987-09-14
Abstract: PURPOSE:To obtain a final passivation film directly in contact with an Si3N4 film so that the passivation film is hardly separated, by providing the size of the final passivation film, which is directly formed on the Si3N4 film in a wafer process, so that the shape of the passivation film is in contact with the Si surface of a substrate and the size exceeds from a scribing line by a specified length. CONSTITUTION:An Si3N4 film 7 is provided at a layer, where a chip is directly in contact with a final passivation film 8 in a semiconductor device. When said semiconductor device is manufactured, the final passivation film 8, which is directly formed on the Si3N4 in a wafer process, exceeds from a scribing line 9 by at least 5mum or more. The film 8 is in contact with the surface of Si in a substrate. The size of the film 8 is formed in this way. Even if alignment is deviated slightly in a possible occasions, an exposing part, where the passivation film 8 is not overlapped on the Si3N4 film, is not yielded. The entire insulating film part is covered with the final passivation film 8 along all the part. Therefore, the final passivation film 8 is not separated, and moisture resistance is improved.

Title: Water film forming device of manufacturing device for resin film
Inventor: OKASHIRO HIDETOSHI
IPC: B29L7/00
Filed: 1992-08-27
Abstract: PURPOSE:To provide a water film forming device which can form a water film having a uniform thickness on a casting drum. CONSTITUTION:A wet air supply pipe 91 for guiding wet air to a wet air blow- off device arranged in the close vicinity to a casting drum from a wet air generating device 80 possesses a supply pipe 91 and heater 93 arranged so as to coat the supply pipe 92 with the heater 93. Since the wet air passing through the inside of the supply pipe 92 is heated by the heater 93, it is hard to condense. Then since the wet air supply pipe 91 is inclined in an accilivity manner toward a dew part from the wet air generating device 80, moisture stuck to the inside is apt to return within the wet air generating device 80. Therefore, the wet air having stabilized moisture can be supplied to the wet air blow-off device.

Title: Preventive agent for clogging, scale and corrosion of drain pipe for air conditioner
Inventor: KAJIWARA SHOICHIRO
IPC: C02F5/10
Filed: 1986-09-29
Abstract: PURPOSE:To prevent the clogging in a drain pipe by the generation of slime for a long period of time, sticking of scale thereto and corrosion thereof by using a preventive agent formed by incorporating a hydrazine compd., scale preventive agent and corrosion preventive agent as effective components into said agent, mixing the same with a binder and molding the mixture. CONSTITUTION:The hydrazine compd. slightly soluble in water (e.g., hydrazine sulfate), the scale preventive agent slightly soluble in water and the corrosion preventive agent (e.g., calcium phosphonate salt) are incorporated as the essential components into said agent and are mixed and kneaded with the binder (e.g., PE glycol which is a high polymer), then the mixture is molded. The chemicals in the preventive agent air dissolved little by little by contact with the generated drain if the titled preventive agent formed in the above-mentioned is installed in the drain receiving tray or near the discharge port of the drain pipe. The effect of preventing the generation of the slime and the sticking of the scale is thereby maintained for along period of time. The clogging in the drain pipe for air conditioning and the sticking of scale thereto are thus prevented for a long period of time.

Title: Composite steel powder
Inventor: KIYOTA SADAKIMI
IPC: B22F1/00
Filed: 1986-09-29
Abstract: PURPOSE:To permit provision of composite steel powder for powder metallurgy with which the highest performance is obtainable by specifying the face-to-face spacing d200 relating to the diffusion of Fe-Ni of the composite steel powder formed by sticking metal or alloy powder contg. Ni at a specific ratio onto the surface of iron powder. CONSTITUTION:This composite steel powder is formed by sticking another metal or alloy powder onto the surface of the iron powder and contains at least 1.0-10wt% Ni in the deposit thereof. The peak of the face-to-face spacing d200 of the Ni-Fe alloy determined by a powder X-ray diffraction ranges 1.765-1.790Angstrom . Ni improves the strength, hardness, toughness, etc., of the matrix of iron of such composite steel powder. The effect is low if the amt. of the Ni to be added is below 1.0%. The formation of the composite steel powder by uniform partial diffusion is difficult and the compressibility thereof is retarded if the amt. exceeds 10%. On the other hand, the compressibility is sharply deteriorated if the peak of the face-to-face spacing d200 exceeds said range. Mechanical properties are considerably deteriorated if the peak is smaller than said range.

IPC: G01N33/48
Filed: 1985-10-16
Abstract: PURPOSE:To reconstitute an image at a high speed by generating a lateral magnetism signal for a desired area of a sample placed in a uniform magnetostatic field, applying a slanting magnetic field generated by the combination of a sine or consine wave function, and taking a measurement. CONSTITUTION:A magnetostatic field is produced by an electromagnetic 1 and a coil 3 detects a signal generated by the object body 2 while establishing a high frequency magnetic field. Slanting magnetic field producing coils 4X, 4Y, and 5 produce slanting magnetic fields in an X, a Y, and a Z direction and those magnetic fields vary in intensity according to commands from an object capacity measuring instrument 11. The high frequency magnetic field which excites nuclear spins of the body 2 is produced by modulating a high frequency wave generated by a synthesizer 12 and supplying the modulated wave to the coil 13. The lateral magnetism signal is obtained by applying a 90 deg. and a -180 deg. high frequency pulse and the slanting magnetic field in the Z direction and the coil 3 generates a magnetism signal indicating the spin density distribution of the body 2 by being applied with the X-directional or Y- directional slanting magnetic field of a sine or cosine wave function, thereby reconstituting a magnetism distribution image at a high speed.

Title: Formation of interconnection
Inventor: SUZUKI SETSUO
IPC: H01L23/52
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To make it possible to form a well-conditioned buried layer in a contact hole of a large aspect ratio and thereby simplify the process and reduce the cost and also make it possible to form interconnection with single interconnection formation material by alternately repeating the formation of an a thin film of interconnection formation material and a treatment for increasing the contact hole filling performance several times. SOLUTION: A thin film of interconnection formation material 2 is formed on a structure which has a contact hole 1 formed in an insulating film 3 and then is reflowed. As a result, there is no overhang which has been existing at the opening of the contact hole 1. Nextly, another thin film of interconnection formation material 2 is formed in a reduced atmosphere and then is reflowed. After the second reflow, a well-conditioned buried layer is formed in the contact hole 1. By increasing the contact hole filling performance, the aspect ratio at which voids generate is increased, in other words, the aspect ratio of the contact hole 1 can be filled without voids can be increased.  By this method, a contact hole with a large aspect ratio can be filled well and thereby the process can be simplified and the cost can also be reduced and, in addition, it is possible to form interconnection with single interconnection formation material.
