A pattern of dielectric structures are formed directly on a substrate in a single step using sol-gel chemistry and molding procedures. The resulting dielectric structures are useful in vacuum applications for electronic devices. Porous, lightweight structures having a high aspect ratio that are suitable for use as spacers between the faceplate and baseplate of a field emission display can be manufactured using this method.

[ The invention claimed is:] [1.] A method for making a pattern of dielectric structures on a substrate, comprising:providing a mold having a pattern of cavities formed therein;filling the cavities in the mold with a precursor solution and removing any trapped air in the cavities;covering the filled mold with a solid substrate in contact with the precursor solution of the filled cavities;allowing the precursor solution to get and attach to the solid substrate;separating the solid substrate with attached gelled structures from the mold;drying the gelled structures to form a pattern of dielectric structures on the solid substrate, andtreating the structures after drying for altering the properties of the structures by spraying a metal alkoxide on the structures.
