摘要:
An electron emitting device with an insulating layer on a substrate. The insulating layer has a hollow part in which a conical electrode is formed. A conductive layer on the insulating layer has an aperture on the hollow part of the insulating layer. The hollow part is formed by etching utilizing an ion beam.
