Abstract:
A semiconductor component comprising:a semiconductor substrate;a first lightly doped drain region in the semiconductor substrate;a second lightly doped drain region in the semiconductor substrate and overlapping a first portion of the first lightly doped drain region;a channel region in the semiconductor substrate and overlapping a second portion of the first lightly doped drain region, a third portion of the first lightly doped drain region separating the channel region from the second lightly doped drain region;a source region in the semiconductor substrate and completely overlapped by the channel region;a drain region in the semiconductor substrate and completely overlapped the second lightly doped drain region;a dielectric structure overlying the semiconductor substrate and the third portion of the first lightly doped drain region;a first gate electrode overlying a portion of the dielectric structure, a portion of the third portion of the first lightly doped drain region, and a portion of the channel region;a second gate electrode overlying portions of the first and second lightly doped drain regions, the second gate electrode absent over the dielectric structure and absent over the channel region;a drain electrode overlying the drain region; anda source electrode overlying the source region, the first and second gate electrodes located between the source and drain electrodes.
