Abstract

CMOS poly-Si TFTs were fabricated through crystallization and GILD processes by a novel selected area laser assisted (SALA) system. The system enables a local area irradiation of small beams of a pulsed solid-state laser of frequency tripled Nd:YAG. The novel TFT process eliminated 3 doping mask steps of the conventional process. On-off current ratios for both types of poly-Si TFTs were improved by SALA. The field effect mobility of n- and p-channel TFTs is 84 cm2/Vs and 75 cm2/Vs, respectively.
