PROBLEM TO BE SOLVED: To provide a semiconductor device with excellent electric characteristics, or a semiconductor device with stable electric characteristics.SOLUTION: A semiconductor device includes a first transistor, a second transistor, a first insulator, a second insulator, a first wire, and a first plug. The first transistor includes silicon, and the second transistor includes an oxide semiconductor. The first insulator is positioned on the first transistor, and the second insulator is positioned on the first insulator. The second transistor is positioned on the second insulator. The first wire is positioned on the second insulator and on the first plug. The first transistor and the second transistor are electrically connected to each other through the first wire and the first plug. The first wire has low hydrogen transmissivity. The second insulator has lower hydrogen transmissivity than the first insulator.SELECTED DRAWING: Figure 1 |
