Abstract: A novel semiconductor device or a semiconductor device capable of preventing overcharging is provided. A power receiving portion has a function of generating a signal for canceling a wireless signal transmitted from a power feeding portion when the charging is completed. Specifically, when the remaining battery capacity of the power receiving portion is one hundred percent or higher than or equal to a predetermined reference value, the power receiving portion has a function of generating an electromagnetic wave for canceling an electromagnetic wave transmitted from the power feeding portion. Thus, a magnetic field for canceling a magnetic field formed of the electromagnetic wave transmitted from the power feeding portion is formed, so that overcurrent in the power receiving portion can be prevented.

Abstract: Graphene is formed with a practically uniform thickness on an uneven object. The object is immersed in a graphene oxide solution, and then taken out of the solution and dried; alternatively, the object and an electrode are immersed therein and voltage is applied between the electrode and the object used as an anode. Graphene oxide is negatively charged, and thus is drawn to and deposited on a surface of the object, with a practically uniform thickness. After that, the object is heated in vacuum or a reducing atmosphere, so that the graphene oxide is reduced to be graphene. In this manner, a graphene layer with a practically uniform thickness can be formed even on a surface of the uneven object.

Abstract: As a display device has a higher definition, the number of pixels, gate lines, and signal lines are increased. When the number of the gate lines and the signal lines are increased, a problem of higher manufacturing cost, because it is difficult to mount an IC chip including a driver circuit for driving of the gate and signal lines by bonding or the like. A pixel portion and a driver circuit for driving the pixel portion are provided over the same substrate, and at least part of the driver circuit includes a thin film transistor using an oxide semiconductor interposed between gate electrodes provided above and below the oxide semiconductor. Therefore, when the pixel portion and the driver portion are provided over the same substrate, manufacturing cost can be reduced.
