Abstract
Island-like semiconductor films and markers are formed prior to laser irradiation. Markers are used as positional references so as not to perform laser irradiation all over the semiconductor within a substrate surface, but to perform a minimum crystallization on at least indispensable portion. Since the time required for laser crystallization can be reduced, it is possible to increase the substrate processing speed. By applying the above-described constitution to a conventional SLS method, a means for solving such problem in the conventional SLS method that the substrate processing efficiency is insufficient, is provided.
