Abstract

The usability of 4H-SiC pin-diodes as nearly linear temperature sensors up to 800 K is demonstrated. Two sensor concepts were evaluated including the constant current forward bias (CCFB) concept and the integrated proportional to absolute temperature (PTAT) concept. The maximum sensitivity was 4.5 mV/K for the CCFB and an applied current density of 118 nA/cm2. Additionally, this device can be used for UV detection, too, demonstrating the feasibility of 4H-SiC multi-sensor integration.
