- Abstract
- This paper presents the depth profile of oxide trap density, extracted from the dual gate processed thermally grown oxide in NO ambient and remote plasma nitrided oxides by using multifrequency and multitemperature charge pumping technique in conjunction with the tunneling model of trapped charges. Ni-trided oxide is widely used to improve the reliability of nanoscale MOSFETs because it can decrease the degradation of gate oxide due to the generation of traps therein. Based on the measurement, the optimum nitrogen concentration in such typical nitrided process is discussed in correlation with the gate oxide thickness for nanoscale CMOSFETs.
