Abstract:	The temperature dependence of TBD and QBD of ultra-thin (3.9 nm thick) gate oxides was studied for p+-poly Si PMOS and n+-poly Si NMOS capacitors. It was observed that the temperature acceleration of TBD exhibits a non-Arrhenius behavior, meaning that no activation energy could be determined. Furthermore for p+ gate devices both TBD and QBD exhibit a stronger temperature dependence compared to n+ poly-Si MOS devices. Also the dependence on the gate voltage is much stronger. This might have consequences for the reliability of p+ gate devices under operating conditions.
