Abstract
The paste dried and hardened on glass substrate for fabrication of the PDP (Plasma Display Panel) barrier rib was selectively etched using focused Ar+ laser ((lambda) =532 nm), the threshold laser fluence was about 6.5 mJ/cm2 for the barrier rib samples softened at 120 degree(s)C. The thickness of 180 (mu) of the sample was completely removed without any damages on the glass substrate by laser fluence of 19.5 J/cm2. In order to increase the etch rate of the barrier rib materials, samples were heated on a hot plate during the laser irradiation. The etch rate at the hot plate temperature of 200 degree(s)C was roughly 4.2 times faster than that of room temperature.
