Abstract
We applied electrical stress in P- and N-channel polysilicon thin film transistors. N-channel devices exhibit two-step degradation with hot-hole injection into the gate oxide followed by electron injection. Stress in P-channel devices provides interesting results in order to clarify the physical mechanisms occurring during device aging
