| Abstract(in English) | Low gate charge power vertical double-diffused MOSFET devices are required for high frequency circuit system. In this study, we proposed a power MOSFET structure with a dual gate structure which realizes the small gate charge without significantly degrading breakdown voltage. The dual gate eliminates partial gate area which effects switching speed and switching loss strongly. The dual gate structure features the formation of removed gate area portion combining with the additional np-region at the surface of the n drift layer. Reduction of the gate charge results in an improvement of switching performance. The gate charge and the figure of merit of the dual gate with np-region cell structure are reduced 49% and 33% compared with those of the conventional cell, respectively. |
