Title: Semiconductor device
Inventor: KANBA KOJI
IPC: H01L21/3205
Filed: 1989-07-14
Abstract: PURPOSE:To prevent an opening area from being reduced and to reduce a contact resistance by a method wherein a sidewall of a silicon nitride film is formed on an inner face of a contact hole which has been made in an insulating film formed by a reflow operation. CONSTITUTION:An oxide film 2 and a borophosphosilicate glass(BPSG) film 3 are formed one after another on a silicon substrate 1; the BPSG film 3 and the oxide film 2 are etched one after another to open a contact hole. After that, a nitride film is formed on the whole surface; it is etched back to form a nitride-film side wall 4 on an inner face of the contact hole, i.e. on a side face of the BPSG film 3 and the oxide film 2. Then, impurities are introduced into the silicon substrate 1 through the contact hole; they are annealed and activated to reduce a contact resistance. During this process, the BPSG film 3 is not melted and its shape is not collapsed. Thereby, it is possible to prevent an opening area of the contact hole from being reduced and to prevent the contact resistance from being increased.

Abstract: PROBLEM TO BE SOLVED: To provide a method for transferring a conductive ball for canceling the pickup miss for a conductive ball, and surely transferring the conductive ball one by one to the electrode of a work. SOLUTION: At the time of vacuum sucking a solder ball 1 by an suction tool 32 mounted at the lower edge of a transfer head 30, the vacuum level of the inside part of the suction tool 32 is detected by a vacuum level measuring part 65, pickup miss is judged when it does not reach a prescribed vacuum level within a prescribed time, the vacuum suction is released, the solder ball 1 is dropped from the suction tool 32, and the pickup is resumed again. Also, at the time of vacuum suction, the suction tool 32 is pressed on the layer of the solder ball stocked in a supply part, and the suction tool 32 is relatively vibrated against the solder ball 1 by driving vibrators 43 and 16. Thus, the solder ball 1 can be guided to a suction hole 35 so as to be quickly sucked.

Title: Casting ingot cutting device
Inventor: ITO TAKESHI
IPC: B22D46/00
Filed: 1999-06-28
Abstract: PROBLEM TO BE SOLVED: To provide a casting ingot cutting device, wherein an ingot can be cut with a small force at a low cost and installation space can be restrained even if a means for automatically transferring the ingot is provided. SOLUTION: This ingot cutting device 8 is equipped with a first holding part 21 for holding one side entire part of a cutting part A of an ingot, and a second holding part 22 for holding the other side entire part, and the second holding part 22 is bent by a principle of a lever so as to cut the ingot. Since a cutting stress is efficiently applied to the cutting part A when cutting, the force required for cutting is efficiently used for cutting. Also, since flexion can be restrained, the ingot is not jumped during cutting and small pieces are not flown off. Furthermore, since the force is amplified by the lever, an inexpensive first air cylinder 24 can be used so as to restrain costs.

Abstract: PURPOSE: To provide a reliable sealing by injecting a curable composition made of free radical polymeric vinyl ester and its rapid free radical curing method compound and having specific viscosity into a groove which exists at least on one of two parts after the curing method becomes inactivated. CONSTITUTION: Free radical polymeric vinyl ester is made of middle to long chain two or polyfunctional value prepolymer having a vinyl reaction terminal group and a cross-linking control monomer which is reactive to a middle to long chain prepolymer, soluble and miscible. A composition is a multiple liquid type composition, one liquid contains an initiator and the other contains an activator, and fluid in a range of 200 to 500,000 mPas at temperature of viscosity 25 deg.C is formed by mixing both of the liquids at the time of injection. Rapid curing is required for performance of sealing in a short period of time and for stopping an excessive flow rate of the composition, and the groove forming a gasket has a cross section of about the maximum 3 mm×3 mm. Consequently, it is possible to form the gasket between two parts at a working site.

IPC: H01L21/322
Filed: 1988-07-21
Abstract: PURPOSE:To enable distribution of internal defect to be uniform when manufacturing a device by cooling it to a room temperature at a specified rate rapidly after heating it to a required temperature by irradiation with light. CONSTITUTION:Light of xenon lamp or halogen lamp is directed to a silicon substrate above 1200 deg.C and then it is cooled down to a room temperature at 2.2 deg.C/sec or more rapidly. With this preliminary treating, cores with a non- uniform internal defect introduced on growth of a silicon single crystal are nearly extinguished and internal defects occur uniformly on the silicon substrate during device production process by a new and highly concentrated atomic empty hole distributed uniformly. Then, concentration of oxygen between grids is reduced at a device active area near the surface, thus resulting in an area without any internal defect.

Title: Thermal recording sheet
Inventor: OGAWA HIDENORI
IPC: B41M5/42
Filed: 1996-07-12
Abstract: PROBLEM TO BE SOLVED: To provide outstanding recording properties and high durability by forming an under layer consisting mainly of filler and binder on the face of the side, on which a thermal recording layer is applied, of unwoven fabric. SOLUTION: Unwoven fabric is made of natural fiber or synthetic fiber or a mixture of these fibers, and the constituent components are not particularly defined. As binder in an under layer, an emulsion of water-soluble polymer or hydrophobic polymer which is commonly used can be properly used. In addition, as pigment contained in the under layer, any type of pigment which is already known can be used. Further, the blended amount of each of the constituent components contained in the under layer is not particularly defined, when it is commonly put into practice in the thermosensitive recording area. The under layer should weight about 3-30g/m<2> in terms of application amount. When the application amount is 3g/m<2> or less, it is impossible to completely conceal the unevenness of the unwoven fabric, and the improvement of image quality is insufficient.  On the other hand, when the application amount is 3g/m<2> or more, the unwoven fabric itself is vulnerable to heat.

Filed: 1983-10-03
Abstract: PURPOSE:To prevent the deformation and shortening of a glass envelope and improve the product yield, by sealing the glass envelope and a lead wire through a bead glass having a lower softening point than the glass envelope under gastight conditions. CONSTITUTION:Each bead glass 12 is mounted on a lead wire 11 fixed to an electrode 10 at one end at a distance from the electrode 10 in the axial direction, and then inserted into the opening end of a glass envelope 13 to form a glass tube. A material having a softening point 50-150 deg.C lower than the glass envelope 13 is used as the bead glasses 12. The glass envelope 13 and lead wires 11 are inserted into an assembling hole 5 and insertion hole 6 of an assembling jig, and the resultant assembly is mounted on the interior of a vacuum vessel, heated in an electricity conduction state, and degassed. The temperature is then increased.
