Abstract
An electronic element is provided which includes a pair of electrodes (referred to as facing electrodes) formed within the groove of an insulating film on the substrate, the end portions of the electrodes being separated and facing each other in the groove. When a voltage of a predetermined value or more is applied between the facing electrodes, there occurs a cold cathode emission which causes a flow of electrons from one of the electrodes to the other. At that time, the facing electrodes are melted by heat generated by the applied voltage, and either a short circuit or insulation between the facing electrodes, is attained, depending on the selected structure of the element. In this way, the electronic element of the present invention can perform the protection of semiconductor devices and semiconductor circuits. Also, the electronic element of the present invention can perform the operation of selecting a desired load resistance to be applied to a specific circuit.
