Abstract
A two-dimensional(2-D) analytical model for substrate effect of lateral power devices is developed. By solving the 2-D Poisson's equation, an analytical model is proposed and verified by the agreements between the analytical results and numerical simulation results using MEDICI. It suggests that the optimized substrate voltage modules the distributions of the surface potential and electrical field, whose effect is equivalent to changing the concentration of the drift region. As a result, the breakdown voltage is improved.
