Semiconductor device
A semiconductor device includes an oxide layer, a source electrode layer in contact with the oxide layer, a first drain electrode layer in contact with the oxide layer, a second drain electrode layer in contact with the oxide layer, a gate insulating film in contact with the oxide layer, a first gate electrode layer overlapping with the source electrode layer and the first drain electrode layer and overlapping with a top surface of the oxide layer with the gate insulating film interposed therebetween, a second gate electrode layer overlapping with the source electrode layer and the second drain electrode layer and overlapping with the top surface of the oxide layer with the gate insulating film interposed therebetween, and a third gate electrode layer overlapping with a side surface of the oxide layer with the gate insulating film interposed therebetween.
