Abstract: The present invention relates to a deflector of a micro-column electron beam apparatus and method for fabricating the same, which forms a seed metal layer and a mask layer on both sides of a substrate, and exposes some of the seed metal layer on which deflecting plates, wirings and pads are to be formed by lithography process using a predetermined mask. The wirings and pads are formed by plating metal on the exposed portion, and some of the metal layer is also exposed on which the deflecting plates are to be formed using a predetermined mask, and then the metal is plated with desired thickness, thereby the deflecting plates are completed. Therefore, by forming plurality of deflecting plates on both sides of the substrate at the same time through plating process, alignment between the deflecting plates formed on both sides of the substrate can be exactly made, and by fabricating a deflector integrated with the substrate and deflecting plates in a batch process, productivity and reproducibility is improved. In addition, since the deflecting plates, wirings and pads are directly formed on the substrate, structural safety is improved and thereby durability is also improved.

Abstract: An electron deflection device responsive to an electrical input signal for producing an output signal includes a focusing array for producing a collimated electron beam input ribbon in the direction of a propagation axis, the input ribbon being elongated along an array axis perpendicular to the propagation axis, and being relatively thin along a deflection axis perpendicular to the array axis and to the propagation axis. The focusing array is preferably a linear array of gated cold cathode units with lens electrodes. The deflection device further includes first and second electrically conductive deflector faces, forming a deflection region therebetween and being disposed so that the propagation-axis passes through the deflection region. The deflection device further includes means responsive to the input signal for applying time varying potentials to the deflector faces so as to produce a modulated electric field in the deflection region for deflecting the input ribbon over the course of a temporal deflection cycle to produce a continuously modulated output ribbon. The deflection device further includes an anode section responsive to the continuously modulated output ribbon for producing an output signal.The output signal can be in the form of an electrical output signal or a chopped output ribbon suitable for input to a high power amplifier, such as a klystron, klystrode, traveling wave tube, distributed amplifier or a gigatron, or to a free electron laser.
