Si and C emission into the oxide layer during the oxidation of silicon carbide and SiO2 growth on the oxide surface were experimentally confirmed from depth profiles of oxidized HfO2/SiC structures. With longer oxidation times, surface SiO2 growth transitioned to oxide/SiC interface growth. The influence of Si and C emission on the oxidation rate was investigated by real-time measurements of the oxide growth rate. Experimental observations of annealing-inserted oxidation and two-temperature oxidation indicated that the emission suppressed the oxidation rate
