| Popis: |
This paper investigates the failure mechanism of Ultra High Voltage JFET (UHV-JFET) under Unclamped Inductive Switching (UIS) test. We explain the ruggedness failure of the Power MOSFETs based on drain impact ionization event, diffusion current flowing through the impact ionization area enhancing the impact ionization level. An optimum drain engineering technique based on device structure and implantation method indicates that the avalanche current and avalanche energy capability per micron width can be enhanced up to 27% and 67% respectively. |
