    Abstract

    TCAD simulation has been recognized as a powerful design tool for insulated gate bipolar transistors (IGBTs). In this work, excellent agreement between 3D TCAD simulations and experimental current-voltage characteristics were obtained in the up to 1000 A/cm2 region for IGBTs with scaled trench-gates. The results of 2D and 3D simulations are compared to discuss the difference in current-voltage characteristics and their physical origins. A method to evaluate the saturation current (JCsat) using a 2D simulation is also presented with an appropriate correction.
