  • Patent number: 11658214
    Abstract: A SiC MOSFET device with alternating p-well widths, including an undulating channel, is described. The undulating channel provides current paths of multiple widths, which enables optimization of on-resistance, transconductance, threshold voltage, and channel length. The multi-width p-well region further defines corresponding multi-width Junction FETs (JFETs). The multi-width JFETs enable improved response to a short-circuit event. A high breakdown voltage is obtained by distributing a high electric field in a JFET of a first width into a JFET of a second width.
