Claim Text:
1. A semiconductor device comprising: a first conductive film over a substrate; a first insulating film over the first conductive film; a first oxide semiconductor film over the first insulating film; a second oxide semiconductor film over the first oxide semiconductor film; a second conductive film and a third conductive film over the first oxide semiconductor film and the second oxide semiconductor film; an oxide insulating film over the second conductive film and the third conductive film; a second insulating film over the oxide insulating film; and a fourth conductive film and a fifth conductive film over the second insulating film, wherein the fourth conductive film is electrically connected to the third conductive film, wherein a region of the fifth conductive film overlaps the first conductive film, the first oxide semiconductor film and the second oxide semiconductor film, and wherein the fourth conductive film and the fifth conductive film comprise the same material.
