Abstract

See full text

A novel metal oxide is provided. A semiconductor device with favorable electrical characteristics is provided. The metal oxide has a plurality of energy gaps, and includes a first region having a high energy level of a conduction band minimum and a second region having an energy level of a conduction band minimum lower than that of the first region. The second region includes more carriers than the first region. A difference between the energy level of the conduction band minimum of the first region and the energy level of the conduction band minimum of the second region is greater than or equal to 0.2 eV.
