Title: Wire bonding method
Inventor: OHASHI YUJI
IPC: H01L21/603
Filed: 1997-07-31
Abstract: PROBLEM TO BE SOLVED: To prevent vibration at the time of landing of a tool by lowering the tool with a load larger than a bonding load being applied to the tool and changing the load linearly from a large one to a small one before the tool touches a bonding point and then bringing the tool into contact with the bonding point in that condition. SOLUTION: From a point A above a first bonding point C to a search level B also above the first bonding point C, a tool is lowered at a high speed by allowing current to flow in a solenoid coil so as to apply a large load W1 to a stopper. From the search level B, the tool is lowered at a low speed by linearly changing current in the solenoid coil in a short time until the load becomes W2 which is appropriate for bonding. When the tool gets into contact with the first bonding point C, ultrasonic waves are generated for a specified period of time and wires are bonded to the first bonding point C with the bonding load W2 . By this method, there is no rapid change in load and therefore the vibration of a transducer can be prevented.

Filed: 1991-08-30
Abstract: PURPOSE:To minimize warp of a semiconductor substrate having an SOT region caused by an existence of an insulator layer. CONSTITUTION:A region which becomes an SOI region and a region which is conductive with a substrate are made composite as one unit. In a wafer state which constitutes a number of units, an SOI region is set to realize a layout of each unit wherein adjacent unit is rotated by 90 deg. mutually. For example, a recessed part 2 is formed on a surface of a wafer 1 and an open groove 3 is formed at an end part of the wafer 1 along a periphery of the recessed part 2. The processed side is directly joined with other wafer and its inside cavity is filled with an insulating material; thereby, a dielectric isolation substrate can be obtained. In the process, layout is formed by rotating an arrangement of the recessed part 2. Thereby, warp can be uniformly dispersed on a wafer surface and warp can be reduced as a whole.

Title: Linearity correcting circuit
Inventor: TANAKA MASAYUKI
IPC: H04N3/23
Filed: 1996-08-02
Abstract: PROBLEM TO BE SOLVED: To reduce an occupying area at the circuit board of a linearity coil and to reduce the bad effect of a magnet on another circuit. SOLUTION: N pieces of coils L1, L2,..., Ln mutually constituting a parallel circuit are coiled around single bar ferrite core 12 to provide a magnet 12 to constitute a composite linearity coil 11. The contact points of a relay for controlling the interrupting of the respective coils are serially connected to all the respective coils L1, L2..., Ln. This relay is controlled by a relay switch control part switching a relay corresponding to the frequency of an inputted horizontal synchronization signal. The relay switch control part turns on and off the relay contact point corresponding to the frequency of the horizontal signal in a prescribed combination to adjust the inductance of the whole of the composite linearity coil 11. As plural coils are collected in a single composite linearity coil 11, an occupying area at the circuit board can be narrowed.  As a magnet 13 becomes only one, the range of the generation of a magnetic flux is narrowed to reduce bad effect.

Abstract: PROBLEM TO BE SOLVED: To prevent the generation of electrolytic bubbles in the fused glass in the spacing between a stirrer and a stirrer tube by avoiding the flow of DC current to the fused glass in the spacing between the stirrer and the stirrer tube. SOLUTION: A potential regulating means 52 sets the potential of an AC power source 50 for heating at the min. in the position of the stirrer 36 to suppress the electromotive force formed in the fused glass G in the spacing between the 36 stirrer and the stirrer tube 31.

As a result, the flow of the DC electric power to the fused glass G is prevented.
