Abstract
A semiconductor device comprising:
- a first semiconductor region of a first conductivity type;a second semiconductor region of a second conductivity type provided on the first semiconductor region;an insulating portion provided on the first semiconductor region;a third semiconductor region of the second conductivity type provided on the second semiconductor region and having a higher carrier concentration of the second conductivity type than that of the second semiconductor region; anda first electrode provided on the insulating portion and the third semiconductor region, the first electrode having a portion which is aligned with the second semiconductor region in a second direction perpendicular to a first direction being from the first semiconductor region to the second semiconductor region, and the first electrode being in contact with the second semiconductor region and the third semiconductor region.
