We have fabricated advanced metal-oxide-semiconductor (MOS) capacitors with ultra thin (5 nm) remote-PECVD SixNy dielectric layers and investigated electrical properties of nitrided SiO2/4H-SiC interface after oxidizing the SixNy in dry oxygen at 1150 °C for 30, 60, 90 min. Improvements of electrical properties have been revealed in capacitance-voltage (C-V) and current density-electrical field (J-E) measurements in comparison with dry oxide. The improvements of SiC MOS capacitors formed by oxidizing the pre-deposited SixNy have been explained in this paper.
