A Fast And Efficient Simulation Tool For The Voltage Handling Capability Of High Voltage Devices
Published online by Cambridge University Press: 10 February 2011
Abstract
The user-oriented simulator POWER2D for studying the voltage handling capability of power semiconductor devices is presented. The simulation is based on the Poisson's equation solution for an arbitrary shaped 1D, 2D, and cylindrical 3D high voltage semiconductor structures. Very fast solution of the potential is obtained for a high level of applied bias, based on incomplete LU decomposition preconditioned biconjugate gradient method, and combined with a multi-damping scheme for the Newton linearization of the non-linear algebraic equations. An original algorithm is developped ensuring a very fast and automatic search of the breakdown via the ionization integrals calculus. The predicting capability of the program is illustrated for different termination techniques showing good agreement with the experiment.
