Abstract

We have fabricated a novel LDD structured polysilicon thin film transistor with a simple fabrication process, compared with the conventional LDD poly-Si TFT, without LDD implantation by employing taper etched $SiO_2$ film instead of LDD implant mask. The leakage current of the novel LDD device is reduced significantly in OFF state while keeping the ON current to be almost identical to that of the non-LDD poly-Si TFTs.
