Abstract:
1. A semiconductor device, comprising: a first electrode disposed on a first surface of a semiconductor substrate; a second electrode disposed on a second surface of the semiconductor substrate, the second surface opposite the first surface; and a first semiconductor region having a first conductivity type and disposed between the first and second electrodes, wherein a first element region of the semiconductor substrate includes: a second element region of the semiconductor substrate includes: a total second conductivity type dopant amount of the second body region in the first element region and within a first block portion of the semiconductor substrate is greater than a total second conductivity type dopant amount of the second anode layer in the second element region within a second block portion of the semiconductor substrate, the first block portion having a width in the first direction that is equal to a spacing between adjacent gate electrodes in the first plurality of gate electrodes and a length of a predetermined distance in a second direction, parallel to the first surface and perpendicular to the first direction, the second block portion having a width and a length that is the same as the first block portion.
