Fast Non-Contact Dielectric Characterization for SiC MOS Processing


Article Preview

Non-contact corona-voltage metrology is utilized to characterize as-grown thermal oxide films on 4H SiC substrates. Contact potential difference mapping is coupled with incremental application of corona charge to provide whole-wafer images of process related effects and multiplepoint capacitance-voltage characteristics respectively. Correspondence between wafer VCPD images and process details is suggested along with examples of fast electrical dielectric thickness determination and non-contact C-V characteristic acquisition.
