Educational tool for teaching of semiconductors

This paper presents an educational tool that enables exploring key aspects on semiconductor theory and power circuit analysis. With this tool it is possible to examine with accuracy the influence of device parameters and circuit parameters on circuit dynamic behavior, analyzing switching waveforms and typical switching parameters. The tool invokes an electrical circuit simulator (IsSpice) in order to simulate a selected circuit with parameters values defined by the user. Simulations are carried out using state-of-the art physics-based models for semiconductor devices. These models provide high quality simulation results and enable the user to explore the influence of technological and geometrical device parameters such as area, doping concentration, lifetime, etc. Besides, the model also provides a solution for the dynamic charge carrier distribution. So, 2D and 3D distribution curves can be easily graphed and compared with voltage/current time waveforins, making clear theoretical relationships concerning semiconductor behavior. Some possible examples to use in classroom are also presented.
