Title: Wire bonding method
Inventor: MORINAKA RYUICHIRO
IPC: H01L21/607
Filed: 1985-07-17
Abstract: PURPOSE:To bond wirings without thermal damage by locally heating a portion to be wire-bonded by a laser light, and then press-bonding gold wirings to the portion by a supersonic vibration. CONSTITUTION:When an optical box 15 is moved to a position where the optical axis of a light projecting port 21 at the lower surface of the box coincides with the central axis of a capillary 6 and stopped, a laser light source 13 is operated to emit a laser light 18 from the port 21 to a portion 3 to be wire- bonded. When the portion 3 is locally heated to the prescribed temperature, the light source 13 is stopped, and the box 15 is laterally moved. When the box 15 moves, the capillary 6 and a horn 10 move down, the lower end of the capillary 6 pushes the gold sphere of Au wirings 5 to the locally heated part of the portion 3, and press-bonds it by a supersonic vibration. Thus, a wire bonding is performed without thermal damage even with the deterioration of thermal resistance.

Title: Method for detecting object to be measured using metallic colloid bonding material and gel used for the method for detection
Inventor: YAMAZAKI MASAHIKO
IPC: G01N33/543
Filed: 1995-06-23
Abstract: PURPOSE: To easily and clearly detect a material to be measured in a short time by causing a reaction between metallic colloid bonded with a specific bonding material and the material to be measured in a specific gel by bringing the material to be measured into contact with the colloid after the colloid is condensed. CONSTITUTION: Metallic colloid is bonded to a specific bonding material by mixing the metallic collide with the solution of the bonding material for five or more minutes at a pH near the isoelectric point of an immunological active material. Because of incorporating the bonded body of the specific bonding material and metallic colloid in a gel, a metallic colloid bonding ligand is made to coexist in the gel when the gel solidifies or the solution of the bonded body of the specific bonding material and metallic colloid is diffused in the gel after the gel is adjusted by bringing the solution into contact with the gel. A specimen containing a material to be measured is added to the gel containing the bonded body of the specific bonding material and metallic colloid.  Then the material to be measured is diffused in the gel and a bonding reaction occurs between the material to be measured and specific bonding material and, as a result, the metallic colloid agglutinates. Since the metallic colloid agglutinates and the color tone of the colloid changes, the material to be measured can be detected and determined when the color tone variation of the gel is measured.

Title: Formation of thin film
Inventor: MATSUKI TAKEO
IPC: C23C14/58
Filed: 1996-06-19
Abstract: PROBLEM TO BE SOLVED: To provide a method for forming a thin film, i.e., a metal oxide dielectric or superdielectric thin film consisting of multiple elements, intended to prevent its property deterioration through eliminating the defect of the constituent elements at the interface between the thin film and a base layer even in the presence of such elements subject to sublimation and/or diffusion into the base layer. SOLUTION: This method of forming a thin film is such one as to form a dielectric thin film consisting of multiple elements through filmforming process. The film-forming process is such one that 1st layer and 2nd layer thin films are accumulatively formed on a base layer and then crystallized to form the dielectric thin film; in this case, for the 1st layer thin film 104 close to the base layer 102, at least one element constituting the thin film is accumulated so as to be greater than the stoichiometric composition of the thin film in consideration of its diffusion out of the thin film.

Filed: 1980-11-11
Abstract: PURPOSE: To refine molten Al efficiently by increasing the temp. gradient of the liq. phase in an impurity thickened layer close to the solidification interface of the Al when a cooling body is put in the molten Al and rotated to precipitate high purity proeutectic Al on the surface.  
     CONSTITUTION: Molten Al 2 is charged in a crucible 1 and always kept at a temp. above the solidification temp. by heating with a heater 5. A hollow cooling body 3 made of refractory with superior heat conductivity such as graphite is immersed in the molten Al 2 and rotated around a shaft 4 while being cooled with a cooling medium such as air or water. The surface of the body 3 is cooled to a temp. below the solidification temp. of Al to precipitate high purity proeutectic Al 9 on the surface. At this time, by regulating the heating of the molten Al with the heater 5 and the cooling with the body 3, the Al solidifying speed on the surface of the body 3 is reduced, an impurity thickened layer close to the solidification interface is made thin, and the temp. gradient in the layer is increased. As a result, the formation of dendrite is prevented, and high purity Al having a smooth surface is precipitated efficiently.

Abstract: PURPOSE:To improve the using efficiency of a picture memory by using a point, which scanning from the origin reaches with the overall length in the horizontal direction of a picture memory as the scanning width, as the coordinate point corresponding to a picture element. CONSTITUTION:When a maximum length of the x-direction address of input picture element data, the y-direction address if input picture data, and the x- direction address of input picture data are denoted as X length, Y, and A respectively, an address AD on a picture memory 3 of input picture data is given by AD=(X length)XY+X to access the picture memory 3, thereby eliminating the x-direction unused area of the picture memory. With respect to conversion of the expression, the overall length of the scanning line to a point (picture element) of coordinates (X,Y) which raster scan of input picture data from the origin with the x-direction scanning width X length reaches is equalized to the overall length of the similar scanning line to the picture element on the picture memory (consequently, the address AD of the picture element). Thus, the using efficiency of the picture memory 3 is improved.
