Patent ID: 8809954

Claim:
A field effect transistor structure comprising: a semiconductor layer having end portions and a center portion between said end portions, said center portion having an area that extends laterally beyond said end portions and said center portion comprising: a channel region between said end portions, said channel region being doped with a first conductivity type dopant such that said channel region has a first conductivity type; and a gate-to-body tunnel current region in said area that extends laterally beyond said end portions, said gate-to-body tunnel current region comprising: a first implant region immediately adjacent to said channel region and doped with said first conductivity type dopant at a higher concentration than said channel region; a second implant region adjacent to said first implant region and doped with a second conductivity type dopant different from said first conductivity type dopant such that said second implant region has a second conductivity type different from said first conductivity type; and an enhanced generation and recombination region at a junction between said first implant region and said second implant region; and a gate structure traversing said center portion.
