Claim 13:
14. The device of claim 13, wherein the polysilicon layer comprises:
a first heavily doped region of a first conductivity type;
a second heavily doped region having a first sub-region and a second sub-region, wherein the first sub-region is of a second conductivity type and the second sub-region is of the first conductivity type, the second conductivity type being different from the first conductivity type;
a third heavily doped region of the second conductivity type;
a first lightly doped region positioned laterally between the first heavily doped region and the second heavily doped region; and
a second lightly doped region positioned laterally between the second heavily doped region and the third heavily doped region.
