摘要

In this paper, the influence of nitrous oxide (N₂O) nitridation temperatures on p-type Pi-gate (PG) poly-Si junctionless accumulation mode (JAM) TFTs is experimentally investigated. The tetraethoxysilane (TEOS) gate oxide quality for PG JAM TFTs can be significantly improved by increasing N₂O nitridation temperatures (T_N) from 700 °C to 800 °C in N₂O ambient, resulting in the improvement of average subthreshold swing (A.S.S.), increase of on current (I_ON ), and enhancement of TEOS gate oxide breakdown E -field (E_OBD). PG JAM TFTs by means of a proper channel doping concentration (N_ch= 5 × 10¹⁸ cm^-3) and a suitable T_N (800 °C) exhibit a steep A.S.S. 96 mV/dec. and a large E_OBD ∼ 12.1 MV/cm.
