Claim 0:
1. A device, comprising:
a semiconductor body with a first type of conductivity, having a first surface and a second surface;
a first body region with a second type of conductivity, extending from the first surface into the semiconductor body;
a junction field effect transistor (JFET) region of the first conductivity type adjacent to the first body region and the first surface;
a first gate structure extending over the first surface and lying partially over the first body region and the JFET region;
an implanted structure, with the second type of conductivity, extending into the JFET region from the first surface,
a second body region with the second type of conductivity, extending from the first surface into the semiconductor body, the JFET region being between the first and second body region;
a first plurality of enriched regions in the first body region and a second plurality of enriched regions in the second body region, wherein the first plurality of enriched regions have the second type of conductivity and the second plurality of enriched regions have the second type of conductivity, wherein the first plurality of enriched regions are offset with respect to the second plurality of enriched regions along a first direction; and
a second gate structure extending over the first surface and lying partially over the second body region and the JFET region, wherein the first gate structure extends along the first direction and partially overlaps the first plurality of enriched regions and the second mate structure extends along the first direction and partially overlaps the second plurality of enriched regions.
