A structure that is suitable for partial or full use in a spacer of a flat-panel display. The structure may be formed with a porous body having a face along which multiple primary pores extend into the porous body. A coating consisting primarily of carbon and having a highly uniform thickness overlies the porous bodys face, extending along the primary pores to coat their surfaces and converting the primary pores into further pores. The coating can be created by removing non-carbon material from carbon-containing species provided along the pores. A solid porous film whose thickness is normally no more than 20 m has a resistivity of 10 -10 ohm-cm. A spacer for a flat-panel display contains a support body and an overlying, normally porous, layer whose resistivity is greater parallel to a face of the support body than perpendicular to the bodys face.

A flat-panel display is fabricated according to a process in which a liquid-containing film ( , or ) is formed over a substrate ( ). In addition to suitable liquid, the liquid-containing film contains oxide or/and hydroxide. Liquid is removed from the liquid-containing film to convert it into a solid porous film ( or ) having (a) a porosity of at least 10% along an exposed face of the film, (b) an average resistivity of 10 -10 ohm-cm at 25Â C. , and (c) an average thickness of no more than 20 m. A spacer ( ) formed with at least a segment of the substrate and overlying solid porous film is positioned between opposing first and second plate structures ( and ) of the display. The second plate structure ( ) emits light upon receiving electrons emitted by the first plate structure ( ).

A structure suitable for partial or full use in a spacer ( ) of a flat-panel display has a porous face ( ). The structure may be formed with multiple aggregates ( ) of coated particles ( ) bonded together in an open manner to form pores ( ). A coating ( ) consisting primarily of carbon and having a highly uniform thickness may extend into pores of a porous body ( ). The coating can be created by removing non-carbon material from carbon-containing species provided along the pores. A solid porous film ( ) whose thickness is normally no more than 20 m has a resistivity of 10 -10 ohm-cm. A spacer for a flat-panel display contains a support body ( ) and an overlying, normally porous, layer ( ) whose resistivity is greater parallel to a face of the support body than perpendicular to the bodys face.

The present invention further provides a spacer assembly which accomplishes the above achievement and which does not degrade severely when subjected to electron bombardment. The present invention further provides a spacer assembly which accomplishes both of the above-listed achievements and which does not significantly contribute to contamination of the vacuum environment of the flat panel display or be susceptible to contamination that may evolve within the tube. Specifically, in one embodiment, the present invention is comprised of a spacer structure which has a specific secondary electron emission coefficient function associated therewith. The material comprising the spacer structure is tailored to provide a secondary electron emission coefficient of approximately 1 for the spacer assembly when the spacer assembly is subjected to flat panel display operating voltages.
