Popis: We have shown that r.f. sputtered Si films crystallized by cw Ar/sup +/ laser irradiation is a suitable material for fabrication of polysilicon TFTs. Polycrystalline Si film with proper annealing condition has a high Hall mobility up to 120 cm/sup 2//V-s in p-type samples. The dependence of dark conductivity on temperature suggests that much reduced trap density in laser-annealed Si films is the reason for the high mobility, despite the fact that the grain size is only 30 nm.
