Cold cathode passive matrix FEDs are fabricated by depositing a resistive layer on a substrate, and coated with a protective layer in which at least one hole is formed. Cathode material is deposited on the protective layer making direct contact with the resistive layer through the hole to form bases for the emitter tips which are subsequently etched from the cathode layer. The protective layer allows overetching of the cathode material to prevent tip-to-tip electrical shorts without attacking the underlying resistive layer.
