Abstract
A semiconductor device of embodiments includes: a first electrode; a second electrode; a gate electrode extending in a first direction; and a SiC layer. The SiC layer includes: a first conductive type first SiC region having a first region, a second region facing the gate electrode, and a third region in contact with the first electrode; a second conductive type second SiC region between the second region and the third region; a second conductive type third SiC region, the second region interposed between the second SiC region and the third SiC region; a second conductive type fourth SiC region, the third region interposed between the second SiC region and the fourth SiC region; a first conductive type fifth SiC region; a second conductive type sixth SiC region between the first region and the second SiC region; and a second conductive type seventh SiC region between the first region and the second SiC region and distant from the sixth SiC region in the first direction.
