Claim Text:
1. A semiconductor thin-film manufacturing method comprising: forming an amorphous silicon film above a substrate, the amorphous silicon film having a photoluminescence (PL) intensity greater than or equal to 0.65 when photon energy is 1.1 eV in a PL spectrum normalized to have a maximum PL intensity of 1, the amorphous silicon film including pseudo-crystal nuclei with an average grain size of at most 1 nm, the amorphous silicon film further including a pseudo-crystal nucleus region in which a density of bonds between atoms having an amorphous structure is less than a density of bonds between atoms having a pseudo-crystal structure; annealing the amorphous silicon film; and inducing, during the annealing, crystallization by solid phase crystallization to form a crystalline silicon film.
