Abstract: PURPOSE:To enable to single-crystallize the entire part of a silicon island by a method wherein a laser beam reflection preventing film is provided on the circumference of a polycrystalline silicon island, and a temperature distribution is established in such a manner that the temperature of the circumferential part will be made higher than that of the center part. CONSTITUTION:A laser beam having the spot size larger than the width A of a polycrystalline silicon 27 is made to irradiate. When said laser beam is scanned in the longitudinal direction (as shown by an arrow) of the silicon 27 at the scanning speed of 12.5cm/sec., the silicon 27 is fused, but as the reflectivity of the circumferential region 31 of a silicon nitride film 29, which functions as a reflection preventing film, becomes approximately zero, the laser power which is made to irradiate from the center part of the polycrystalline silicon 27 can be made stronger. The circumferential region 31 is brought in a high temperature state, a recrystallization directing to the circumference is started with the silicon region already crystallized in the center part as a nucleus. The silicon which moved close to the solution side as the growth of crystal makes progress by surface tension and expansion in solidification is pressed by the silicon nitride film 29 as a reflection preventing film formed on the circumferential part of the silicon 27 with a stepping, and the surface of the silicon 27 can be maintained flat.
