Abstract

Pulsed laser irradiation at 248 nm can ablate Si atoms from an Si wafer. The mechanism of this photoablation has been examined by laser-induced fluorescence analysis of the Si products. The Si atoms are measured to leave the wafer surface with averaged translational energy of 2.5 kcal/mol. The distribution of translational energy is well described by the theoretical model for non-cascade ablation processes.
