The Design Of High Voltage Devices, Power Integrated Circuits

Power integrated circuit is one of the most important branches of integrated circuit. As the bridge of the control and execution part of the system, it plays an important role in the fields of electronic power, automatic control, communication and automotive. Owing to the requirement of big current and high voltage, the design of power devices is the key point in the research on power integrated circuit, and it has directly influenced the development of power integrated circuit. Therefore, many big microelectronics companies now focus on power integrated circuits.First, the general introduction of power integrated circuit is presented in this paper. And then some terminal techniques on PIC, devices simulation theory, RESURFs effect and MEDICI software are presented. At last three kinds of high voltage power devices have been designed and simulated. Based on the analysis of the breakdown voltage and electric field distribution of the high power devices, the key physics and structural parameters effects on the breakdown voltage are found. The electrical property curves and parameters are basically consistent with those offered by the company.To complete most of design work and get some useful conclusion, 2-D devices simulation software MEDICI was used. The project is believed to be valuable to the future research on PIC.
