摘要： A field emission cold cathode element designed with the objects of enabling control of overcurrents that arise at times of discharge without adding a power source or complicating the operating circuits, realizing high-frequency operation and lower power consumption without giving rise to short-circuit damage due to discharge breakdown, and moreover, suppressing increases in element temperature; wherein an n-type region underlying emitters is divided between three n-type semiconductor regions: a first n-type semiconductor region, a second n-type semiconductor region and a third n-type semiconductor region. A third n-type semiconductor region below the emitters formed so as to be surrounded by a p-type semiconductor region, a second n-type semiconductor region below the third n-type semiconductor region formed so as to be surrounded by a p-type semiconductor region, and a first n-type semiconductor region formed below the second n-type semiconductor region; wherein the cross section of the second n-type semiconductor region is smaller than the cross section of the third n-type semiconductor region, thereby producing an n-type region made up of three n-type semiconductor regions that has a constricted shape.

摘要： In a field emission cold cathode device including one emitter, a supporting region formed of a conductor or a semiconductor for supporting the emitter, and a gate electrode provided in the proximity of the emitter, electrons are supplied to the emitter from a capacitance formed by a pair of electrodes separated from each other, one of the pair of electrodes being DC connected to the emitter. The emitted electron amount can be controlled by controlling a voltage applied to the other of the pair of electrodes. Thus, it is possible to minimize the variation in the emission current caused by variation in the emitter devices, which was unavoidable in the prior art.
