Abstract
Disclosed is a spacer of a flat panel display (FPD) and a method for preparing the same. The method for preparing a spacer of the present invention includes: (a) exposing a photosensitive glass to a light; (b) heat-treating the exposed photosensitive glass to crystallize it; (c) etching the crystallized glass to prepare the spacer; and (d) heat-treating the spacer under a reductive gas atmosphere. The spacer can be easily prepared by the method according to the present invention, and it has improved conductivity on its surface. A flat panel display including the spacer prepared by the method of the present invention has enhanced conductivity. Therefore, the spacer prevents secondary electron emission, spacer charging, and deviation of electron beams.

A method for preparing a spacer for a flat panel display, the method comprising the steps of:
- exposing a photosensitive glass comprising silver (Ag)-containing compound to a light;
- causing an Ag-nucleation reaction on the photosensitive glass;
- crystallizing the photosensitive glass by heat-treating the photosensitive glass;
- etching the crystallized glass to prepare the spacer;
- and
- heat-treating the spacer under a reductive gas atmosphere.
A method of preparing a spacer for a flat panel display, the method comprising the steps of:
- providing a photosensitive glass comprising LiO2 and Ag2O;
- masking a first area of said photosensitive glass;
- exposing said photosensitive glass to ultraviolet rays, wherein said ultraviolet rays are blocked in said first area;
- heat-treating said photosensitive glass at about 500° C. to cause an Ag-nucleation reaction on said photosensitive glass;
- and
- heat-treating said photosensitive glass at about 600° C. to form a crystallized glass;
- etching said crystallized glass to prepare the spacer;
- and
- heat-treating said spacer under an environment comprising a reductive gas.
