Coupled non-destructive methods, Kelvin Force Probe microscopy and µ-Raman to characterize doping in 4H-SiC power devices
Résumé
Investigation of the doped areas in 4H-SiC power devices has been done by non-destructive characterization methods. It consists of local measurements of the surface potential by Kelvin Probe Force Microscopy (KPFM) coupled with scanning electron microscopy and µ-Raman spectroscopy. Near-field mappings of the devices' surface have been realized and allow us to differentiate their differently doped areas.
