Abstract(in English) We investigated the characteristics of the polycrystalline-Si (poly-Si) film fabricated by excimer laser annealing (ELA) on the SiO_2 substrate (SiO_2 (100nm) / glass), SiN substrate(SiO_2 (50nm) / SiN(50nm) / glass) and quartz substrate from a viewpoint of the stress relaxation. It is clarified by optical method for the first time that the internal stress of the recrystallized poly-Si strongly depends on the substrate film structure. The disk-shaped grains are generated in the poly-Si film on the quartz substrate, on the other hand, the secandary crystal grain growth occurs in the poly-Si on the SiO_2 substrate to relax the internal stress of it. These phenomena are discussed by taking into consideration of the relationship between the Raman peak shift or the full width of half maximum (FWHM) of TO phonon peak and the energy density or the shot number. The solid phase crystallization (SPC) model considering the hydrogen molecules is also inferred.
