Abstract:
A method for fabricating an electron source, comprising a step of forming electron emission regions at respective ones of a plurality of conductive thin film members connected to row wirings and column wirings in a matrix, said step of forming electron emission regions comprising (a) a first step of applying pulse voltages, each of which comprises a pulse sequence, respectively to the row wirings to form fissures in the conductive film members connected to the row wirings associated with the applied pulse voltages, and (b) a second step of applying pulse voltages, each of which comprises a pulse sequence, respectively to the row wirings in an atmosphere of a source gas to produce at least one of a semiconductor, metal oxide, carbon, carbide, and metal film, on the conductive film members connected to the row wirings associated with those applied pulse voltages, wherein in the first and second steps, the pulse sequence of a pulse voltage applied to individual ones of the row wirings is phase-shifted relative to the pulse sequence of a pulse voltage applied to at least one other of the row wirings.
