Provided is a transistor defying a deformation. Alternatively, provided is a transistor entailing little electrical characteristic abnormality. Alternatively, provided is a transistor with a high withstand voltage. A semiconductor device includes a first conductor, a second conductor, a first semiconductor, a second semiconductor, a third semiconductor, and an insulator. The second semiconductor has a region in contact with an upper surface of the first semiconductor. The first conductor has a region where the first conductor and the second semiconductor are superposed. The insulator is arranged between the first conductor and the first semiconductor. The second conductor has a region in contact with an upper surface of the second semiconductor, and the third semiconductor has a region in contact with the upper surface of the first semiconductor, the upper surface of the second semiconductor, and an upper surface of the second conductor. |
