Patent JP-S62276837-A (JP)
Title: Semiconductor device
Inventor: SAWARA KUNIZO
IPC: H05K3/34
Filed: 1986-05-26
Abstract: PURPOSE:To connect an acceptable semiconductor chip to the wiring of a mounting substrate satisfactorily and securely by a method wherein a protruded electrode, soldered with the solder bump of a defective semiconductor chip, has a shape so as to be able to be cut off between the semiconductor chip and the mounting substrate and the remaining protruded electrode is utilized. CONSTITUTION:The part between the solder bump 3 of a semiconductor chip 1 and the protruded electrode 3 of a mounting substrate 2 is narrower than the junction between the solder bump 3 and the semiconductor chip 1 or than the junction between the protruded electrode 3 of the muonting substrate 2. Therefore, the soldered part has a side view of the shape of a hand drum. When a defective semiconductor chip 1 is to be removed, if the semiconductor chip 1 is vibrated along the direction of an arrow by, for instance, ultrasonic wave or the like, the soldered part can be broken at the intermediate narrow part. With this constitution, when the semiconductor chip is removed from the mounting substrate, the protruded electrodes can be left with approximately uniform heights so that the acceptable semiconductor chip, by which the defective semiconductor chip is replaced, can be connected to the wiring on the mounting substrate satisfactorily and securely.

Title: Method of forming film and manufacture of semiconductor device employing the same
Inventor: OSHIKA KATSUSHI
IPC: H01L21/318
Filed: 1986-05-26
Abstract: PURPOSE:To form an AlN film on the surface of an object to be treated such as a GaAs wafer without giving damages to the surface of the object to be treated by a method wherein nitrogen containing organic aluminum compound is decomposed by heat and the AlN film is formed on the surface of the object to be treated. CONSTITUTION:Wafers 17 which are made of GaAs and are to be treated in a required process are mounted on a jig 18 made of quartz and positioned at a predetermined position in a reaction chamber 16 of a reaction furnace. While the wafers 17 are being heated to the required temperature by outside heaters H, diethylamino diethylaluminum (Et2AlNEt2) vapor, which is nitrogen containing organic metal compound, is supplied as source gas S1 with carrier gas S2 such as nitrogen. If the Et2AlNEt2 vapor is made to flow and is contacted with the wafers 17 which are heated to the predetermined or higher temperature, the Et2AlNEt2 is decomposed by heat on the surfaces of the wafers and aluminum nitride (AlN) is produced and deposited on the surfaces of the wafers. At that time, even if the wafer 17 temperature is as low as about 400 deg.C, the AlN film can be easily formed.

Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To provide superior balance at high-speed rotation and enhance machin ing efficiency and machining accuracy without decreasing the holding force of a tool. SOLUTION: The peripheral part 22 of a main spindle 21 corresponding to a female tapered part 4 is formed to gradually enlarge in its diameter so that deformation quantity in the diameter direction caused by centrifugal force may be equal at each position x in the axial direction of the female tapered part 4.  A method for determining the radius of each cross section at the peripheral part 22 is to be considered as the main spindle 21 is an aggregate of a hollow disk having microthickness, and deformation quantity δk (or δo) in the diameter direction of the minimum diameter part (or the maximum dia. part) of the tapered part 4 when the hollow disk rotates at angular speed ωis obtained, and the radius Rx of the main spindle is determined so that the deformation quantity δx in the diameter direction at each position x in the axial direction may be equal to deformation quantity δk (or δo). The result uniformly expands the tapered part 4 by the centrifugal force, but varies no taper angle, declining no collet 5 relative to the main spindle 21.

Title: Magneto-optical recorder
Inventor: ITO HIROSHI
IPC: G11B11/105
Filed: 1989-05-12
Abstract: PURPOSE:To securely erase information and to obtain excellent overwrite characteristics by unproviding a guide groove on an information recording part of an information recording medium. CONSTITUTION:No guide groove for making a beam spot follow is provided on a disk of the magneto-optical recorder capable of overwriting information only by optical modulation without changing the size and direction of an impressing magnetic field for recording and erasing information. Consequently, since thermal conduction is not impeded in the radial direction of the disk, and hence a temp. gradient can be secured enough, a control on magnetic domains can securely be performed. By this method, no erasing remainder of information takes place, and hence the high reliable overwriting is feasible.

Title: Placing base for wafer cassette
Inventor: HARA KOZO
IPC: B65H1/28
Filed: 1987-05-18
Abstract: PURPOSE:To prevent a wafer from damaging by so inclining a placing base body at a predetermined angle that the wafer is disposed at a predetermined position in the bottom of a wafer cassette, and then disposing inclining means for disposing the body horizontally. CONSTITUTION:When a placing base body 1 is raised to its top by a driving mechanism and a wafer cassette 3 is placed, the body 1 is inclined at a predetermined angle by a pressing member 8. When the body 1 is moved down, the body 1 is separated from the member 8 to be disposed horizontally. Accordingly, when the cassette 3 is placed, many semiconductor wafers 2 in the cassette 3 can be disposed at a predetermined position in a state the wafers 2 are brought into contact with the bottom of the cassette 3. For example, when the wafer 2 is removed by a wafer transfer mechanism, the wafer 2 is removed from the horizontal cassette 3. Thus, it can prevent the waver transfer mechanism from being held in a state that the wafer is displaced from the predetermined position or the wafer from being brought into contact with the transfer mechanism to damage the wafer.
