Abstract:
A method comprising the steps of:forming, over a substrate, a liquid-containing film which comprises liquid and precursor material of at least one of oxide and hydroxide; processing the liquid-containing film to remove liquid from the liquid-containing film and convert it into a solid porous film having (a) a porosity of at least 10% along an exposed face of the solid porous film, (b) an average electrical resistivity of 108-1014 ohm-cm at 25Â° C., and (c) an average thickness of no more than 20 &mgr;m; and positioning, between opposing first and second plate structures of a flat-panel display for which the second plate structure produces an image upon receiving electrons emitted by the first plate structure during operation of the display, a spacer comprising at least a segment of the substrate and overlying solid porous film.
