Abstract

A new technique for local deep level transient spectroscopy imaging using super-higher-order scanning nonlinear dielectric microscopy is proposed. Using this technique, SiO2/SiC structure samples with different post oxidation annealing conditions were measured. We observed that the local DLTS signal decreases with post oxidation annealing (POA), which agrees with the well-known phenomena that POA reduces trap density. Furthermore, obtained local DLTS images had dark and bright areas, which is considered to show the trap distribution at/near SiO2/SiC interface.
