Abstract
PURPOSE: To leave a region, a crystal orientation of which coincides with a substrate, and to form single crystal thin films, crystal orientations of which agree with the single crystal substrate, stably even in two layers or more, using the region section as species by composing a melting region in the single crystal thin-films as species so as to be made smaller than the pattern of the thin-films.
CONSTITUTION: An SiO2 film 2 is formed onto a single crystal silicon substrate 1 in 2μm, and an exposed section in the substrate 1 is patterned, thus shaping an opening section 1a 2μm square. A polycrystalline silicon film 3 in 0.5μm and an SiO2 film in 0.26μm are formed, sections from the exposed section 1a are scanned with beams 5 in melting width of 60μm, the silicon film 3 is changed into a single crystal, and a single crystal silicon film 6, a crystal orientation of which coincides with the substrate 1, is acquired. The film 4 is etched, the film 6 is patterned, and a single crystal silicon film 7 50μm square as species is acquired. An SiO2 film 8, an opening section 7a, a polycrystalline silicon film 9 and an SiO2 film 10 are shaped in the same manner as mentioned above, sections from an exposed section in the film 7 are scanned, the film 9 is turned into a single crystal, employing the film 7 as species, and a single crystal silicon film 13, a crystal orientation of which agrees with the substrate 1, is obtained.
