Abstract
To provide a manufacturing method of a field emission cathode, which method exerts no adverse effect on element characteristics at the time when etching is performed with an ion beam. A sacrificial layermade of a thermosetting resin is formed on a gate electrode layer. An opening sectionis formed in the sacrificial layerand the gate electrode layerby irradiating a focused ion beam, and a hole sectionis formed by etching the insulating layerby using the sacrificial layerand the gate electrode layeras a mask. An emitter electrodeis formed in the hole section, and the emitter materialon the sacrificial layeris removed together with the sacrificial layeron the gate electrode layer
