A qualitative comparison study of analog performance of junction and junctionless poly-Si TFTs
In this work, a qualitative comparison study of analog performance of junction and junctionless poly-Si TFTs is carefully investigated. According to numerical simulations, we find out that both gm and gD of junction poly-Si TFT are higher than the junctionless poly-Si TFT at a fixed IDS. Based on the same S/D doping concentration the junctionless poly-Si TFT can have a better short-channel behavior than its counterpart. Thus, it can be proved that a junctionless poly-Si TFT is a good option for AMLCD and AMOLED Applications.
