Abstract

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 body's 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 &mgr;m has a resistivity of 108-1014 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.
