Abstract

A new self-aligned a-Si TFT has been proposed. The TFT has the highly conductive n+ poly-Si source and drain with self-aligned manner. The key process technique employed to this TFT is of excimer-laser selective recrystallization. Two ways have been successfully demonstrated to acheive the selectivity of recrystallization. The fabricated TFT had the field- effect mobility of 0.8cm2/Vs and high on/off current-ratio more than 107.
