Semiconductor device, RF tag, and electronic device
A semiconductor device with a reduced area is provided. The semiconductor device includes a first transistor and a second transistor. The first transistor includes a first conductor and a second conductor arranged with a distance therebetween, a first insulator over the first conductor and the second conductor, a semiconductor over the first insulator, a second insulator over the semiconductor, a third conductor over the second insulator, and a fourth conductor and a fifth conductor that are in contact with the semiconductor. The first conductor includes a region not overlapping with the third conductor with the semiconductor therebetween, the first conductor includes a region overlapping with the second conductor with the semiconductor therebetween, and one of a source electrode and a drain electrode of the second transistor is electrically connected to the third conductor of the first transistor.
