INVESTIGATION INTO THE PROPERTIES OF THE EXPLICIT METHOD FOR THE RESOLUTION OF THE SEMICONDUCTOR-DEVICE EQUATIONS

Most simulators use a Newton-like method for solving the semiconductor device equations. The linearized system obtained by this method is th en solved either directly or iteratively. However, it is also possible to use an explicit method instead of the implicit Newton method. This method was first introduced by Kurata [1] for the semiconductor equat ions. This paper will revise and improve Kurata's explicit method and show the properties and limitations of the algorithm. The main limitat ion of the method is the long computation time needed. However, the me thod benefits from a very simple algorithm, low memory requirements, a nd highly parallel properties.
