Abstract
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 &mgr;m has a resistivity of 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 body's face.
