Publication number: 20060110868Abstract: A method is disclosed to make a lightly doped drain of a low-temperature poly-silicon thin film transistor. Nitrogen is implanted during steps of doping the source and the drain so as to suppress the spreading of the other types of dope so that the poly-silicon layer forms a shallow interface lightly doped drain after annealing. Implantation of nitrogen takes place before or after the other types of dope. Nitrogen is implanted to a depth no greater than that of the other types of dope. The present is simple, improves hot carrier effect and repairs flaws in the poly-silicon layer.Type: ApplicationFiled: December 29, 2004Publication date: May 25, 2006Applicant: ChungHwa Picture Tubes., LTDInventors: Chia-Nan Shen, Cheng-Nan Hsieh, Po-Chih Liu
