Abstract:
    A method of producing ceramic components used for protecting semiconductor devices such as ICs, LSIs, etc., from an abnormal high voltage due to noise, pulse, static electricity, etc., which can eliminate and suppress radio frequency noise in a signal line by reducing the impedance of the devices. To accomplish this object, at least one pulse is applied between electrodes (2). The pulse has a maximum amplitude of not greater than 50 kV, a time interval of not greater than 200 nsec from its initial to maximum amplitude, a total duration of not greater than 1 (my)sec, and energy of not greater than 0.5 Joule.
