Design and fabrication of high voltage planar devices
Abstract
In order to design modern power and high voltage devices, specific tools, either analytical for a first order evaluation, and numerical, solving the basic electrical equations of those devices in two dimensions are developed. Two kinds of electrical behavior: off and on state, both static are dealt with. The peculiar data extracted with those tools are the voltage handling capability and the on resistance of the device. For off state behavior, analytical models are able to rate the avalanche breakdown criterion. To complete the first order evaluation, a special purpose software dedicated to power and high voltage devices, is elaborated to solve in two dimensions the basic semiconductor equations, namely Poisson and current equations, and to give the value of the breakdown voltage, using either holes or electrons integral ionization, and its location.
