Latest Patents

One of his latest patents is for a Silicon-carbide (SiC) metal-oxide-semiconductor field-effect transistor (MOSFET) with short circuit protection. This innovative device integrates a MOSFET-JFET structure made from a SiC wafer, featuring an N+ source, P body diode, and upper N regions that form vertical MOSFETs on the sidewalls of polysilicon gates. The design includes an N substrate that forms a drift region, which is pinched by the JFET to limit saturation current. Trenches are strategically formed between the MOSFETs, and JFETs are created by doping the bottom and sidewalls of these trenches to form P+ taps to the N substrate. The P islands within the N substrate are designed to taper, providing a unique shape to the JFET depletion region that effectively limits saturation current while reducing linear-region ON resistance.

Another notable patent is for a high voltage power device with hybrid Schottky trenches and a method of fabricating the same. This silicon carbide diode features a silicon carbide substrate and a thinner silicon carbide layer on top, which has lower doping than the substrate. The design includes two first lower barrier metal portions on the silicon carbide layer, separated along the top surface, and a first higher barrier metal portion connected to these lower portions. This configuration significantly improves the reverse breakdown voltage of the silicon carbide diode by reducing leakage current at the junction barrier.
