Based on the thermionic emission theory, a method to extract parameters of Si SBD is given in this study. Using this model, we tested the characteristics of devices and extracted the parameters of two kinds of samples. The ideality factor is 1.01 and 2.13 respectively. The zero-field barrier height is 0.70eV and 0.72eV. The surface state density is 5.5×10~(15)cm~(-2)eV~(-1) and 4.3×10~(12)cm~(-2)eV~(-1). The interface oxide capacitance is 9.0×10~(-4)F·cm~(-2) and 5.4×10~(-6)F·cm~(-2). The neutral level of the surface states is 0.81eV and 1.1eV. The reverse breakdown voltage is 101V and 56V.
