Abstract
- Performance limitations of superjunction (SJ) devices due to charge imbalance (CI) are analyzed in this paper. It is demonstrated that in the presence of CI, the specific on-resistance has a quadratic dependence on blocking voltage, similar to a conventional drift region. We also show that by designing the SJ structure with an optimally modified pillar doping, we can achieve better performance under conditions of CI. The design guidelines presented in this paper are applicable to any semiconductor, although all calculations are based on silicon carbide. [ABSTRACT FROM AUTHOR]
