Publication number: 20090253251Abstract: A spin addition method for catalyst elements is simple and very important technique, because the minimum amount of a catalyst element necessary for crystallization can be easily added by controlling the catalyst element concentration within a catalyst element solution, but there is a problem in that uniformity in the amount of added catalyst element within a substrate is poor. The non-uniformity in the amount of added catalyst element within the substrate is thought to influence fluctuation in crystallinity of a crystalline semiconductor film that has undergone thermal crystallization, and exert a bad influence on the electrical characteristics of TFTs finally structured by the crystalline semiconductor film. The present invention solves this problem with the aforementioned conventional technique.Type: ApplicationFiled: November 12, 2008Publication date: October 8, 2009Applicants: SEMICONDUCTOR ENERGY LABORATORY CO., LTD., SHARP KABUSHIKI KAISHAInventors: Misako NAKAZAWA, Toshiji HAMATANI, Naoki MAKITA
