  • Patent number: 11990519
    Abstract: An embodiment relates to a n-type planar gate DMOSFET comprising a Silicon Carbide (SiC) substrate. The SiC substrate includes a N+ substrate, a N? drift layer, a P-well region and a first N+ source region within each P-well region. A second N+ source region is formed between the P-well region and a source metal via a silicide layer. During third quadrant operation of the DMOSFET, the second N+ source region starts depleting when a source terminal is positively biased with respect to a drain terminal. The second N+ source region impacts turn-on voltage of body diode regions of the DMOSFET by establishing short-circuitry between the P-well region and the source metal when the second N+ source region is completely depleted.
