  • Publication number: 20230246102
    Abstract: A superjunction semiconductor device having a termination structure portion surrounding an active region in a plan view. The device includes: a semiconductor substrate; a first semiconductor layer provided on the semiconductor substrate; and a parallel pn structure and a channel stopper provided in the first semiconductor layer. The channel stopper surrounds the parallel pn structure in the plan view, and contacts the parallel pn structure in the termination structure portion. The parallel pn structure includes a plurality of first columns each having a first width and a plurality of second columns each having a second width that repeatedly alternate one another parallel to the main surface. In a region of the parallel pn structure contacting the channel stopper, a product of the second width and an impurity concentration of the second columns is less than a product of the first width and an impurity concentration of the first columns.
