Abstract (en)

[origin: EP0908916A1] A method of manufacturing an electron source with electron emitting elements is provided. The method has a process of depositing a deposit substance in an area including at least an area of the electron emitting element from which area electrons are emitted. The depositing process is performed in an atmosphere of a gas containing at least a source material of the deposit substance, the gas having a mean free path allowing the gas to take a viscous flow state. <IMAGE>
