  • Patent number: 5908340
    Abstract: A method for fabricating an array of conical electron emitters (410) includes the steps of: (i) positioning a collimator (160), including a plurality of collimation cells (162) having hexagonal cross-sections, between a substrate (155) having emitter wells (130) and a target (170) made from the emitter material, (ii) sputtering the target (170) so that it is partially collimated by the collimator (160), (iii) moving the substrate (155) within a plane defined by the substrate (155) so that the emitter wells (130) follow an emitter well path (220) which forms a path angle (235) with respect to a reference line (240) of the collimator (160).
