Title: Manufacture of semiconductor integrated circuit device
Inventor: KIMURA TAKEMI
IPC: H01L29/41
Filed: 1983-02-08
Abstract: PURPOSE:To form a highly reliable contact by depositing a silicon film on aluminum. CONSTITUTION:After forming a field silicon oxide film 8, gate, diffusion layer 1, inter-layer insulating film 9 on a single crystal silicon substrate 6, a contact hole 2 is formed by a photo etching. Then, aluminum 3 is deposited on the entire part and a silicon film 4 is stacked thereon and the aluminum 3 and the film 4 are selectively etched. The film 4 on aluminum 3 is eliminated, leaving the hole 2 and its periphery. A damage occurring when aluminum 3 is deposited is eliminated and alloying is executed for ensuring sufficient contactness between aluminum 3 and diffusion layer 1. Thereby, silicon which forms eutectic crystal with aluminum at the time of alloying is supplied from the silicon film 4 left by the previous processing and it is prevented to penetrate deeply into the substrate. Thereby alloyspike can also be prevented.

Title: Coating mechanism and id card protective layer forming device having this mechanism
Inventor: NISHI YASUO
IPC: B42D15/10
Filed: 1988-01-29
Abstract: PURPOSE:To always fix the direction of coating of a transfer roll by controlling the position of a photographic sensitive material to make it parallel with the coating direction and supplying it so that the photosensitive surface is directed to the transfer roll and controlling the position of the photographic sensitive material between the transfer roll and a back roll to make it parallel with the axial direction of the transfer roll. CONSTITUTION:The position of a supplied card-shaped photographic sensitive material 2 is so controlled that it is parallel with the coating direction, and its photosensitive surface is directed to a transfer roll 402 and the material 2 is supplied between the transfer roll 402 and a back roll 403. Since the coating speed based on rotation of the transfer roll 402 is lower than the supply speed of the photographic sensitive material 2, the position of the photographic sensitive material 2 is accurately controlled again to make it parallel with the axial direction of the transfer roll 402 when the photographic sensitive material 2 is brought into contact with the transfer roll 402. Since two stages of position control are performed in this manner, the direction of coating of the transfer roll 402 is always fixed.

Abstract: PURPOSE: To enhance reaction rate of a reactive mixture by producing a composite of capturing reagent/analyte/indicator and bringing the composite into contact with a solid phase substance charged oppositely to separate the composite from a fluid sample thereby detecting a label. CONSTITUTION: A fluid sample is brought into contact with a capturing reagent to produce a composite of capturing reagent/analyte and then the composite is brought into contact with an indicator to produce a composite of capturing reagent/analyte/indicator. The composite is brought into contact with a solid phase substance charged oppositely and separated from a fluid sample through attraction and adhesion thus detecting and monitoring a label associated with a solid phase or an unbonded indicator as an index of the presence of an analyte in fluid sample or the quantity thereof. Both the capturing reagent and indicator being used in the separation process are soluble and dispersed into the fluid sample to produce a uniform reaction mixture thus enhancing the reaction rate of reaction mixture.

Abstract: PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive capable of continuously forming a coating pattern excellent in clarity and accuracy by the screen printing method or the like without causing cobwebbing or the like to form a pressure-sensitive adhesive layer excellent in tackiness. SOLUTION: A radiation-curing, pressure-sensitive adhesive which comprises a mixture of an alkyl acrylate and an oligomer and/or polymer, has a viscosity of at least 50P and forms a string having a length of not longer than 100mm when the tip of a column having a diameter of 10mm is buried therein in a depth of 5mm and raised at a rate of 0.5m/sec. Thus, a pressure-sensitive adhesive layer excellent in the adhesive characteristics can be formed by the radiation polymerization (curing), and the pressure-sensitive adhesive layer excellent in the pattern accuracy can be continuously formed while keeping a high reproducibility, suitably keeping the shape and thickness of the coating pattern, avoiding the film formation by drying, and keeping the shape of the coating pattern from changing by the removal of the solvent, flow deformation, etc.  Further, the drying treatment with an oven or the like is unnecessary and thus the apparatus can be made more compact.

Abstract: PROBLEM TO BE SOLVED: To enable parallel measurement by one optical apparatus by providing the apparatus with a structure taking out the light emitted from the constructed part of the discharge path of a deuterium lamp from the front and the rear. SOLUTION: A deuterium lamp 1 being a light source has a structure capable of taking out light in two directions and has light taking-out windows 2, 2' and, even if the light emitted from the discharge constricted part of the lamp 1 is taken out in two directions, respective quantities of light are almost equal. The lights emitted in two directions are condensed to incident slits 4, 4' by concave mirrors 3, 3' and spectrally diffracted by concave diffraction lattices 5, 5. The spectrally diffracted monochromatic light is divided into two lights by half mirrors 6, 6' and the respective lights pass through emitting slits 7, 7' to pass through sample analyzing cells 8, 8' to be incident on photodetectors 9, 9' composed of photodiodes and converted to electric signals.  The reflected lights from the half mirrors 6, 6' are used as reference lights and incident on photodetectors 10, 10' to be converted to electric signals. By this constitution, a double beam optical system of two systems is obtained and a measuring time can be shortened.
