Abstract: An electron emission device adapted to enhanced electron beam focusing and its method of fabrication are shown. The device includes driving electrodes for controlling the emission of electrons from electron emission regions formed on a substrate; two or more tiers of insulating layers formed on the driving electrodes; and a focusing electrode formed over the tiers. A multi-tiered insulating layer allows a thick tier to hold the focusing electrodes away from the emission regions, thus enhancing their focusing impact, while a thin tier under the focusing electrodes remains amenable to intricate patterning. Fabrication of the tiers from material with different etching rates allows thicker lower support tiers to be etched during the same period and in the same step that a thinner upper tier is etched, also allowing openings in a lower tier to widen while openings in the upper tier stay small.

Abstract: In a method of manufacturing an electron emission device, cathode electrodes are first formed on a substrate. An insulating layer is formed on the entire surface of the substrate such that the insulating layer covers the cathode electrodes. The insulating layer is wet-etched two or more times such that openings each with an aspect ratio of more than 1 are formed in the insulating layer. Gate electrodes are formed on the insulating layer. Electron emission regions are formed on the cathode electrodes within the openings of the insulating layer. The respective etchings are conducted using separate mask patterns with the same-sized openings such that under-cuts are made.
