Abstract:
1. A method of manufacturing an electron source, comprising the steps of: (A) providing a substrate on which a plurality of units and wirings are arranged, each unit including a pair of electrodes and a polymer film connecting the pair of electrodes, and the wirings being electrically connected to each of the plurality of units; (B) supplying an energy to respective polymer films of the units to reduce a resistivity of each of the polymer films, and (C) forming a gap in each of films obtained by reducing the resistivity of the polymer films, wherein step (B) includes scanning a spot irradiation of an energy beam onto a selected one or ones of the polymer films and then the spot irradiation of the energy beam is moved to irradiate another one or ones of the polymer films, and the scanning is repeated so that the energy supply to each of the polymer films is conducted a plurality of times.
