ABSTRACT:
Structures and methods of manufacture for field emission cathodes having cathode tips of minute size, whereby a block formed of pairs of substrates each having a patterned thin layer of cathode material sandwiched therebetween is sliced into a plurality of sections, to obtain array substrates each having an array of exposed regions of cathode material. A metal layer for constituting electron extraction electrodes and corresponding extraction apertures is formed over these exposed regions and appropriately shaped, after first forming mask layer portions upon the exposed cathode material regions.
