Paper Abstract

Nanosecond resolution measurements were performed to investigate the change of reflectivity of polymers (PolyMethylMethacrylate and PolyImide) under ArF excimer laser irradiation. The temperature increase due to the irradiation was also calculated. From the results of the experiments and calculations we concluded that several processes influence the observed changes in optical properties of the irradiated polymer samples, such as the quickly expanding gas that leaves the surface immediately after the incidence of the excimer pulse, thermal decomposition of the surface layer and the decrease of the refractive index caused by the heat.
