Abstract
The capacitance-voltage (C-V) chracteristics of thin nitrided thermal oxides prepared by rapid termal nitridation(RTN) have been studied. The threshold voltages were calculated using C-V measurement and found to vary as the concentration of acceptor and the thickness of oxynitride. When the Si02 films were annealed in NH3 a decrease in the positive oxide charge due to Si-N bond was observed. In the case applied frequency is high and low, the high frequency depletion capacitance was higher than that of low frequency, which is indicative of high frequency surface conduction by mobile surface charge.
