Inventor: SATOU TOMOTOSHI
IPC: H01L21/60
Filed: 1996-05-24
Abstract: PROBLEM TO BE SOLVED: To prevent a bonding defect and prevent the clogging of a capillary, by detecting the bonding detect, based on whether the absolute value of the output voltage of a torch power source to apply high voltages is over the preset value or not. SOLUTION: In the case of forming a bump by ball bonding method, the bonding defect is detected, based on whether the absolute vale of the output voltage of a torch power source 1 to apply high voltage is over the preset value or not. Fox example, if a high level of output can be gotten from the comparison circuit by comparing the output voltage value of the torch power source 1 divided with resistors with the judgment criteria voltage value corrected by the value of the resistance by means of a comparison circuit 2, it is judged that it was a misjudge. Then, an RS flip-flop 3 is set with the output of the comparison circuit 2, and is reset by the rest signal from a computer for control after input of data to indicate that it is faulty into the computer of control.

Filed: 1986-06-04
Abstract: PURPOSE:To make it possible to perform high speed modulation readily without using external modulation, by imparting a potential to electrodes, thereby yielding difference in refractive indexes of two lightguides, and selectively taking out two light beams, which are oscillated in the two lightguides and have phase difference, into an output lightguide. CONSTITUTION:On the a substrate 1, the following parts are provided: two parallel lightguides 2 and 3, which are optically coupled; a coupling device 4, where the two lightguides 2 and 3 are coupled; an output lightguide 5 connected to the coupling device 4; and electrodes 6 on the surface of the substrate. Two light beams having phase difference are oscillated in the two lightguides 2 and 3, which serve the roles of laser units. When a potential is imparted to the electrodes 6, the difference in refractive indexes is yielded between the two lightguides 2 and 3. Then either of the two light beams is selectively taken out by said optical switching action and put into the output lightguide 5. The light is emitted to the outside of the substrate 1. In order to make large-capacity transmission possible in this way, phase modulation characterized by excellent high-speed property and transmission efficiency of the optical switch utilizing the electroptical effect is used.

Abstract: PURPOSE:To quickly restore a system by sending a signal indicating segments of processes and a fault detection signal from the copy source side to the copy destination side and providing a buffer storage on the copy destination side and completing the copying operation after completion of copy of the process, which is copied at present, at the time of reporting fault detection. CONSTITUTION:When a CPU 10 writes data in a main storage device (MM) 20 through an operating bus 30, a duplex controller (MXC) 40 transfers its write address and write data to an MXC 41 through an address data communication bus (X bus) 50. When the fault of the CPU 10, the MM 20, or the bus 30 is detected, it is reported to the MXC 41 by a signal line ERR 60. The MXC 41 stores received write address and data in an internal buffer storage (BUF) 42. The MXC 41 successively reads out stored write address and data and writes them in an MM 21 of the copy destination to complete the copying operation. Thus, the system is quickly restored.
