Interfacial thermal resistance (ITR) plays a great important role in the thermal design of SiC power device modules. However, experimentally measuring the ITR between thermal interface material (TIM) and SiC is still challenging as a result of a lack of efficient measurement methods. Optical-Interference Contactless Thermometry (OICT) can measure the transient internal wafer temperature with high spatial and temporal resolutions. Based on this method, ITR at the SU-8 /SiC interface has been measured.
