Abstract
Provided is a semiconductor device that can suppress a leakage current more than has been achieved before. A semiconductor deviceincludes a first carrier holding layer, which is arranged on a lower electrode, is in contact with a lower electrodevia a first interface, and includes majority carriers of one type, and a second carrier holding layer, which is arranged on the first carrier holding layer, defines a second interfaceconstituting a conduction path to the first carrier holding layer, and includes majority carriers of the other type. The first interfacehas its outline within the outline of the first carrier holding layerwhen seen in a plan view in a direction that is orthogonal to a surface of the substrate, and the second interfacehas its outline within the outline of the first carrier holding layerwhen seen in the plan view.
