Abstract

PURPOSE:To make the crystallinity of a semiconductor thin film favorable by a method wherein crystallization of the semiconductor is promoted by heating the semiconductor film with laser beams generating from mutually facing laser beam sources. CONSTITUTION:An SiO2 film 2 is formed on a transparent insulating substrate 1, and the Si film 3 is formed moreover on the upper face thereof to form a large areal thin film semiconductor forming body 5, the laser beam sources are provided facing mutually in the vertical direction interposing the forming body between them, the thin film semiconductor forming body 5 and the laser beam sources facing mutually in the vertical direction are equipped transferrably relatively, and laser beams 6, 7 from the laser beam sources are irradiated toward the forming body 5. Contour lines in the thin film become nearly perpendicular to the substrate 1 as shown in dotted lines 8, flow of heat becomes in parallel with the substrate 1, and heat currents in eight directions become dominant. Accordingly the Si thin film 3 consisting of large crystal nuclei 10 can be obtained.
