Abstract:
The degree of integration of a semiconductor device is enhanced and the storage capacity per unit area is increased. The semiconductor device includes a first transistor provided in a semiconductor substrate and a second transistor provided over the first transistor. In addition, an upper portion of a semiconductor layer of the second transistor is in contact with a wiring, and a lower portion thereof is in contact with a gate electrode of the first transistor. With such a structure, the wiring and the gate electrode of the first transistor can serve as a source electrode and a drain electrode of the second transistor, respectively. Accordingly, the area occupied by the semiconductor device can be reduced.

Claim (Index 2):
A semiconductor device comprising:\n a first transistor comprising:\n an oxide semiconductor layer; \n an insulating layer over the oxide semiconductor layer; and \n a gate over the insulating layer; and \n a second transistor comprising a conductive layer, wherein; the oxide semiconductor layer comprises a pair of regions and a channel therebetween; the gate overlaps with the channel, the pair of regions contains an impurity, and has a lower resistivity than the channel, one of the pair of regions is electrically connected to the conductive layer, and in a cross-sectional view of the semiconductor device, the channel overlaps with a source or a drain of the second transistor.
