Electrical instabilities in p-channel polysilicon TFTs: role of hot carrier and self-heating effects

  • Published : 2007.08.27

Abstract

The effects of hot carriers and self-heating on the electrical stability of p-channel TFTs have been analysed combining experimental data and numerical simulations. While hot carrier effects were shown not to induce appreciable degradation, self-heating related instability was found to more seriously affect the device characteristics. New models have been developed to explain the reported results.
