Abstract: The present invention relates to a method for manufacturing a CIGS thin film which does not require an additional Se supply during rapid thermal processing (RTP), by performing the rapid thermal processing after forming a Cu-In-Ga-Se precursor thin film containing a Se component. Specifically, the method for manufacturing a CIGS thin film comprises the steps of forming a Cu-In-Ga-Se precursor thin film containing selenium in a substrate (step a); and performing rapid thermal processing to the precursor thin film formed in step a at a temperature exceeding 400°C and below 600°C and at a pressure of 1 to 760 torr for 1 to 30 minutes (step b). The present invention allows the precursor thin film to contain a sufficient amount of Se in itself in the process of manufacturing the CIGS precursor thin film. Therefore the precursor thin film does not require an additional Se supply during the rapid thermal processing, thereby minimizing loss of Se from controlling the rapid thermal processing conditions and providing a high crystalline CIGS thin film.
