发明名称 OXIDE SEMICONDUCTOR FILM AND SEMICONDUCTOR DEVICE
摘要 An oxide semiconductor film which has more stable electric conductivity is provided. The oxide semiconductor film comprises a crystalline region. The oxide semiconductor film has a first peak of electron diffraction intensity with a full width at half maximum of greater than or equal to 0.4 nm−1 and less than or equal to 0.7 nm−1 in a region where a magnitude of a scattering vector is greater than or equal to 3.3 nm−1 and less than or equal to 4.1 nm−1. The oxide semiconductor film has a second peak of electron diffraction intensity with a full width at half maximum of greater than or equal to 0.45 nm−1 and less than or equal to 1.4 nm−1 in a region where a magnitude of a scattering vector is greater than or equal to 5.5 nm−1 and less than or equal to 7.1 nm−1.
