Abstract

A structure suitable for partial or full use in a spacer (24) of a flat-panel display has a porous face (54). The structure may be formed with multiple aggregates (100) of coated particles (102) bonded together in an open manner to form pores (58). A coating (88) consisting primarily of carbon and having a highly uniform thickness may extend into pores of a porous body (46). The coating can be created by removing non-carbon material from carbon-containing species provided along the pores. A solid porous film (82) whose thickness is normally no more than 20 &mgr;m has a resistivity of 108-1014 ohm-cm. A spacer for a flat-panel display contains a support body (80) and an overlying, normally porous, layer (82) whose resistivity is greater parallel to a face of the support body than perpendicular to the body's face.
