Abstract
A semiconductor storage device comprises a plurality of memory cells arranged in a matrix. Each of the memory cells includes: a semiconductor storage element including a silicon carbide substrate and a silicon carbide film on a first surface of the silicon carbide substrate; a lower electrode on a second surface facing away from the first surface of the silicon carbide substrate; and an upper electrode on at least part of a surface of the silicon carbide film, the surface facing away from another surface of the silicon carbide film in contact with the silicon carbide substrate. Each memory cell includes at least one basal plane dislocation formed at at least part of the semiconductor storage element.
