Abstract

We have studied the effect of ion doping on the electrical properties for atmospheric pressute chemical vapor deposition (APCVD) amorphous silicon (a-Si) films. The room temperature conductivities after ion doping at optimurr doping tenperatures for n and p-type a-Si films were found to be > 10−2 and >10−4 S/cm, respectively. The unintentional hydrogen incorporation into a-Si during ion doping enhances the quality of ion doped APCVD a-Si as compared to that of plasma enhanced CVD (PECVD) a-Si:H. We obtained the field effect mobility of > 1 cm2/Vs for APCVD a-Si TFT using ion doped n+-layer.
