Abstract:
A transistor formed in a semiconductor material of a first conductivity type, the transistor comprising:spaced-apart source and drain regions of a second conductivity type formed in the semiconductor material, the source region includes: a first lightly-doped region, a first heavily-doped region that is formed in the first lightly-doped region, and a second heavily-doped region that adjoins the first lightly-doped region and is spaced apart from the first heavily-doped region; and the drain region includes: a second lightly-doped region, a third heavily-doped region that is formed in the second lightly-doped region, and a fourth heavily-doped region that adjoins the second lightly-doped region and is spaced apart from the third heavily-doped region.
