  • Patent number: 5520759
    Abstract: The present invention relates to a method for manufacture of ceramic parts used for protecting semiconductor devices such as IC, LSI, etc. against anomalous high voltages such as noise, pulse, static electricity, etc. and the object of the present invention is to provide ceramic parts capable of removing or restraining high-frequency noises on signal lines by reducing the impedance of the devices.In order to attain the above object, according to the present invention, a pulse voltage of 50 kV in maximum value which requires a time of 200 nanoseconds or less for reaching the maximum value from an initial value and a time of 1 microsecond or less for returning to the initial value through the maximum value and which has an energy of 0.5 joule or lower is applied at least once between the electrodes (2).
