ABSTRACT:
An electrode structure including a plurality of beam control electrodes, a plurality of electrically insulating spacers disposed between each pair of neighboring members of the beam control electrodes, an electrode substrate, a plurality of metallic pins planted on the beam control electrode so as to extend therefrom through the electrode substrate, and a fixing member mounted on each of the metallic pins from behind the electrode substrate for retaining the beam control electrodes. The electrode structure is manufactured by abutting a first support bench of high rigidity against the beam control electrodes in a predetermined shape and abutting a second support bench of high rigidity in a predetermined shape from behind the electrode substrate, applying a predetermined load to the electrode structure, applying a predetermined load to the fixing member to press the latter towards the electrode substrate, and welding each of the metallic pins and the associated fixing members together by the use of a laser welding process.
