Abstract
A semiconductor integrated circuit includes: a semiconductor base body of a first conductivity-type; a bottom surface electrode to which a first potential is applied, the bottom surface electrode being provided on a bottom surface of the semiconductor base body; a first well of a second conductivity-type to which a second potential lower than the first potential is applied, the first well being provided on a top surface side of the semiconductor base body; a second well of the first conductivity-type provided in the first well; and an edge structure provided in the first well and configured to supply a third potential higher than the second potential to the second well.
