A field emission device with integrally formed electrostatic lens and method of forming.

摘要

A FED including an integrally formed electrostatic lens (37) with an aperture having a diameter which is dissimilar from an aperture of the FED gate (31) to effect a reduction in electron beam cross-section. By forming the FED with an electrostatic lens aperture of increased diameter relative to the diameter of the gate aperture a reduced sensitivity with respect to lens thickness and location is realized as is a relaxation of electrostatic lens fabrication constraints. Image display devices employing such integrally formed electrostatic lens systems may be provided wherein pixel cross-sections as small as two microns are realized. <IMAGE>
