Abstract:
1. A process for fabricating an electron emitting device, comprising the steps: (A) providing a structure which comprises a first conductive layer, an insulating layer disposed on said first conductive layer and a second conductive layer disposed on said insulating layer wherein a first hole penetrates to said first conductive layer through said insulating layer and said second conductive layer; (B) depositing a layer of material for an electron emitting member, onto the inner surface of said first hole; (C) forming a second hole which penetrates through at least said second conductive layer amongst said insulating layer and said second conductive layer, the second hole being juxtaposed with said first hole; and (D) etching a part of said insulating layer interposed between said juxtaposed first and second holes until said first and second holes are communicated with each other, wherein said step (D) is conducted after step (B) and step (C).
