SEMICONDUCTOR DEVICE, MODULE, AND ELECTRONIC DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a semiconductor device with small parasitic capacitance, and alternatively, to provide a semiconductor device with low power consumption.SOLUTION: A semiconductor device includes a transistor and a capacitive element. The transistor includes a first conductor, a first insulator over the first conductor, a semiconductor including a region overlapping with the first conductor with the first insulator interposed therebetween, a second insulator over the semiconductor, a second conductor including a region overlapping with the semiconductor with the second insulator interposed therebetween, and a third conductor and a fourth conductor including a region in contact with a top surface of the semiconductor. The capacitive element includes a layer formed from the same layer as the first conductor and a layer formed from the same layer as the third conductor and the fourth conductor.
