Abstract:
A change in electrical characteristics of a transistor including an oxide semiconductor film is suppressed. The transistor includes a first gate electrode, a first insulating film over the first gate electrode, an oxide semiconductor film over the first insulating film, a source electrode over the oxide semiconductor film, a drain electrode over the oxide semiconductor film, a second insulating film over the oxide semiconductor film, the source electrode, and the drain electrode, and a second gate electrode over the second insulating film; the first insulating film includes a first opening; a connection electrode electrically connected to the first gate electrode through the first opening is formed over the first insulating film; the second insulating film includes a second opening that reaches the connection electrode; the second gate electrode includes an oxide conductive film and a metal film over the oxide conductive film; and the connection electrode and the second gate electrode are electrically connected to each other through the metal film.

Claim (Index 11):
The semiconductor device according to  claim 2 ,\n wherein the source electrode and the drain electrode each comprise a first metal film, a second metal film over and in contact with the first metal film, and a third metal film over and in contact with the second metal film, wherein the second metal film comprises copper, wherein the first metal film and the third metal film each comprise a material that suppresses diffusion of the copper, wherein an end portion of the first metal film comprises a region located outward from an end portion of the second metal film, and wherein the third metal film covers a top surface and a side surface of the second metal film and comprises a region in contact with the first metal film.
