Simulation of Static-Characteristics of Lightly-doped-drain Polysilicon Thin Film Transistors
摘要
Abstract
purpose of reducing the p-Si TFT off-state current, the structures of lightly doped drain (LDD) were used. Applying a homojunction model of semiconductor theory and considering the off-state current modified by hot carrier effect, the static-characteristics of LDD p-Si TFT were simulated. The on/off current switching ratios of p-Si TFT were investigated by a series of LDD doping concentrations and lengths.The LDD structures reduce TFT′s off-state current to 10-11 A and increase the on/off current switching ratios of p-Si TFT to 106. The results will be valuable referencepoints for designing and fabricating of p-Si TFT.关键词
