Patent ID: 7417270

Claim:
A Junction Field Effect Transistor (JFET) comprising: a semiconductor layer of a first conductivity type; a well region of a second conductivity type formed in a substrate, the well region including a channel region having an average dopant concentration substantially less than the average doping concentration of the remaining laterally adjacent portions of the well region, and wherein the channel region comprises a plurality of alternating implant and diffusion regions of the second conductivity type, the plurality of separate implant regions being separated from one another by the plurality of separate diffusion regions, the implant regions having a higher average dopant concentration than the diffusion regions; a source region and a drain region of the second conductivity type arranged in a spaced apart relationship in the well region; a gate region of the first conductivity type interposed between the source region and the drain region and extending through the channel region of the well region, the gate region being segmented into a plurality of separate portions, the plurality of separate portions of the gate region being coincident with the plurality of separate implant regions and being within the plurality of separate implant regions.
