What changed from existing technology?
This study shows that dividing the source contact in 4H-SiC MOSFETs can reduce input capacitance and leakage current, but may increase on-resistance and forward voltage.
This is the first study to investigate source contact segmentation as a layout technique for optimizing the electrical performance of 4H-SiC planar MOSFETs.
