摘要: A single crystal and a polycrystal having an excellent crystal quality and providing a highly reliable semiconductor device are formed by solid phase growth at low temperatures. An amorphous thin film is deposited on a substrate such that an average inter-atomic distance of main constituent element of the amorphous thin film is 1.02 times or more of an average inter-atomic distance of the elements in single crystal, and crystallization energy is applied to the amorphous thin film to perform solid phase growth to thereby form a single crystal. In another embodiment of the present invention, an amorphous semiconductor thin film is formed on a substrate or an insulating film such that an average inter-atomic distance distribution of main constituent element of the film substantially coincides with an average inter-atomic distance distribution of the element in a single crystal, and crystallization energy is applied to the amorphous semiconductor thin film to cause solid phase growth to thereby form a single crystalline semiconductor thin film.
