Title: Information processing system
Inventor: KUROZUMI HIROAKI
IPC: G06F15/177
Filed: 1984-06-11
Abstract: PURPOSE:To prevent a system in which a fault is not generated, from becoming a down-state, by providing a means for discriminating whether a memory of the own system is brought to access from a CPU of the own system, or brought to access from a CPU of the other system, on each channel. CONSTITUTION:A channel 5A inputs a signal from a bus monitoring part 3A which has decided that a system B is abnormal, from a terminal 9-2 and sets an FF8. Subsequently, a CPU1A inputs a readout signal from a terminal 9-5 of the channel 5A by a flow of an abnormality processing program, and knows a state of the FF8. Since the FF8 is set, the channel 5A knows that it has been brought to access from a CPU of the system B. Therefore, the CPU1A returns to the processing routine of the own system and continues the processing. When the system B becomes aware of abnormal access, it drops a securing signal of a connecting line 6, and the channel 5A informs it to the CPU1A. The CPU1A sends a reset signal from a terminal 9-4, and resets the FF8.

Title: Method of evaluating corrosiveness of sealing resin
Inventor: TAKIGAWA YUKIO
IPC: H01L21/66
Filed: 1987-05-15
Abstract: PURPOSE:To evaluate the corrosiveness of sealing resin accurately by a method wherein the cured sealing resin is ground and, after pure water is added to it, put in a pressure cooker to extract impurity ions and then an aluminum wiring pattern is dipped in the extracted solution and the resistance variation of the wiring is measured. CONSTITUTION:After epoxy resin is applied to a metal plate, the resin is heated and cured. After the cured resin is peeled off and ground into particles with a certain diameter, the ground resin is mixed with pure water with a certain mixing ratio and the mixture is put in a pressure cooker to extract impurities in the resin into the pure water. A sample is formed by forming a quasi Al wiring pattern on a glass plate and the wiring part of the sample is dipped in the extracted solution. A voltage is applied between the Al wiring pattern and the impurity ions are made to discharge to the Al wiring to induce corrosion. The corrosiveness is evaluated by measuring the rate of resistance variation caused by the corrosion and by visual inspection. With this constitution, the corrosiveness of the sealing resin for a semiconductor IC can be evaluated quickly and the sealing resin compound can be selected easily.
