Abstract:
A method for manufacturing an electron source, including an activation operation for repetitively applying a pulse voltage to a plurality of electron-emitting devices in an atmosphere containing an organic material to form a film containing carbon from the organic material existing in the atmosphere,wherein said activation operation for the plurality of electron-emitting devices is performed in such a manner that said activation operation is divided into a plurality of steps from a first activation step to a final activation step, the plurality of electron-emitting devices are divided into operation units each comprising a plurality of device groups, each of which includes a plurality of electron-emitting devices, the first activation step of the activation operation is sequentially executed from an arbitrary operation unit wherein, in the first activation step, a pulse voltage is applied to each of the plurality of device groups sequentially, and the sequential applying of the voltage is repeated a plurality of times, the first activation step for all of the operation units is terminated, after that, the plurality of electron-emitting devices are divided into operation units each comprising a plurality of device groups, each of which includes a plurality of electron-emitting devices, a next activation step for all of the operation units is terminated in a manner similar to said first activation step, and such a procedure is repeated until the final activation step.
