Claim 14:
15. A MOSFET with a lateral channel in SiC, the MOSFET comprising:
a substrate having a drift layer in contact with the substrate, a buried grid in contact with the drift layer, and a well above the buried grid;
a MOS channel defined by simultaneously formed regions comprising an access region and a JFET region within the well that are laterally self-aligned and have an intermediate part of the well disposed therebetween;
a body diode circuit having a body and a body diode contact, the body in contact with the well and the buried grid, the body diode contact in contact with the body;
an insulating gate oxide on a portion of the source, the access region, the intermediate part of the well, and the JFET region;
a gate contact on the insulating gate oxide;
an isolation layer on the gate contact;
a source in contact with the well and the access region;
a source contact for a MOSFET circuit in contact with the source; and
a drain contact in contact with the substrate.
