A semiconductor device includes a base body portion, a stacked body, a pedestal portion, a plate portion, and first and second columnar portions. The base body portion includes a doped semiconductor film and a semiconductor portion. The doped semiconductor film includes first and second portions. The semiconductor portion includes a first region overlapping the first portion, and a second region overlapping the second portion and being a body different from the first region. The pedestal portion is provided in the second region. The plate portion contacts the pedestal portion and the first region. The first columnar portion includes a semiconductor layer. The semiconductor layer is adjacent to the plate portion with the stacked body interposed, and contacts the first region. The second columnar portion is adjacent to the plate portion with the stacked body interposed, and is adjacent to the pedestal portion with the second region interposed.
