摘要： A field emission cathode that can uniform the number of electrons emitted from each emitter and can prevent a line defect even when a gate electrode is electrically short-circuited with an emitter. The movement of electrons in a channel formed on the channel forming electrode is controlled by applying a positive voltage to the current control electrode, so that the current supplied from the cathode electrode to the emitter can be controlled. If the emitter is short-circuited with the gate electrode, the increased current density destroys the channel, so that the current supply to the emitter can be stopped.
摘要翻译：场发射阴极可以均匀化从每个发射极发射的电子数，并且即使当栅极与发射极电短路时也可以防止线路缺陷。通过向电流控制电极施加正电压来控制形成在沟道形成电极上的沟道中的电子的移动，从而可以控制从阴极供给到发射极的电流。如果发射极与栅电极短路，则增加的电流密度会破坏通道，从而可以停止对发射极的电流供应。

摘要： A cold electron emitting device has an emitter base portion, an emitter projection portion and a source region, each of which is an n-type semiconductor, formed on a p-type silicon substrate. A metal film which serves as an extraction electrode and a gate electrode of FET is formed via an insulating layer on the region of the substrate which includes the peripheral regions of the emitter base portion and source region. This cold electron emitting device can be manufactured as follows. First, a conical emitter having an emitter projection portion and emitter base portion and a source region are formed on a p-type semiconductor substrate. Next, an insulating layer and a metal film, which becomes an extraction electrode and a gate electrode of FET, is formed on the substrate which includes peripheral regions of the emitter base portion and source region. Then, an n-type impurity is doped in the emitter and the source region to form an n-type emitter and an n-type source region. In this manner, it is possible to manufacture a cold electron emitting device, which has an excellent work precision for the sharp tip of the emitter projection portion and an excellent uniform structure and can stably emit a current.

摘要： A field emission element including a gate and an emitter and capable of preventing any of the element oxide layer from being formed on a tip of the emitter to prevent a decrease in emission current, unstable operation and an increase in noise. The gate has a surface formed of a material of oxygen bonding strength higher than that of a material for at least a tip surface of the emitter, so that oxygen atoms and molecules containing oxygen entering the gate may be captured by adsorption on the gate to prevent formation of any oxide layer on the emitter. When a portion of the emitter other than the tip surface is formed of a material of oxygen bonding strength higher than that of the material for the tip surface, formation of any oxide layer on the tip surface of the emitter is minimized.

Emitters each are arranged in each of the openings. The insulating layer is provided on a lower surface thereof with a photoresist layer modified by heating. The modified photoresist layer is electrically connected through a resistive layer to a cathode electrode. The cathode electrode is formed in a pattern on a cathode substrate made of glass or the like.

The photoresist is modified by heating, resulting in being provided with electrical conductivity and exhibiting stable electron emitting characteristics under a low voltage.
