Abstract
A semiconductor product, including: a base region doped with a first conductivity type; a plurality of stripe regions doped with a second conductivity type, provided on an upper surface of the base region, and the second conductivity type is different from the first conductivity type; a plurality of cell regions doped with the second conductivity type, provided on the upper surface of the base region; and a metal layer arranged on the upper surface of the base region, so that the metal layer defines a Schottky barrier with the base region and covers the plurality of stripe regions and the plurality of cell regions; and each cell region of a majority of the plurality of cell regions contacts at least one neighboring stripe region of the plurality of stripe regions and the stripe regions and the cell regions extend into the base region to different depths.
