Abstract:
A method of fabricating an electron source constituted by a plurality of x-direction wirings arranged on a substrate, a plurality of y-direction wirings crossing the x-direction wirings, an insulating layer for electrically insulating the x- and y-direction wirings, and a plurality of conductive films each of which is electrically connected to the x- and y-direction wirings and has a gap, comprising:a conductive film formation step of forming a plurality of conductive films to be connected to the pluralities of x- and y-direction wirings;a grouping step of assigning said x-direction wirings into a plurality of groups; andan energization forming step of sequentially performing, for all the groups, a step of simultaneously applying a voltage to all wirings assigned to the same group, thereby forming gaps in said conductive films, whereinin the grouping step:a plurality of wirings are assigned to each group, so that between wirings constituting a group, wirings constituting other groups are exist.
