Abstract
A method of fabricating spacers for use in a flat panel device includes: preparing a core glass having a low solubility in a chemical etching solution and a tube glass having a high solubility in the chemical etching solution and having a larger inner diameter than an outer diameter of the core glass; inserting the core glass into the tube glass to obtain a cylindrical glass; drawing the cylindrical glass at a predetermined temperature until the core glass has a predetermined diameter; cutting the drawn cylindrical glass to a predetermined length; and removing the tube glass in the cylindrical glass using the chemical etching solution.
