Method for forming ribs in a plasma display panel

Abstract

This invention provides a method for forming ribs in a plasma display panel (PDP). The PDP includes a glass substrate, and a plurality of address electrodes are formed on the glass substrate. A dielectric layer is formed above the address electrodes and the glass substrate. A plurality of sandblasting stoppers are formed on the dielectric layer, and the positions of these stoppers are corresponded to that of the address electrodes. The rib material layer is further formed to cover the dielectric layer and the sandblasting stoppers, and then a plurality of sand-resists are patterned on the rib material layer. By using the sand-resists as a mask, a sandblasting process is executed to form a plurality of ribs and expose the sandblasting stoppers. After removing the sand-resists and the sandblasting stoppers, the structures of the ribs are fixed by a sinter process.
