Among the many polytypes of SiC, 4H-SiC has attracted great attention as a candidate material for the next generation of power semiconductor devices, due to the excellent physical properties such as the electric breakdown field and mobility.
The doping dependent bulk mobility model commonly used in the device simulator is based on the model suggested by Caughey and Thomas [1]: 0 5000 10000 15000 20000 25000 30000 50 100 150 200 250 300 Commercial Sample UPR Sample Electron Mobility(cm 2/Vs) Temperature (K) Figure 1: Top view of a test chip that consists of the elements for physical property measurements Figure 2: Comparison of the mobility as a function of the temperature of a commercial epi-wafer and the epi-wafer, in the case that our group grew the epitaxial layer (UPR sample) Journal Title and Volume Number (to be inserted by the publisher) 3 α µµ µ µ )/(1 )( ref imp min max min impB NN N + − += , (1) where impN denotes the total concentration of ionized impurities, and the reference mobilities maxµ , minµ , the reference concentration refN , and the exponent α are fitting parameters.
