Abstract
A semiconductor device and a logic device formed of the semiconductor device are provided. The semiconductor device includes a first field effect transistor (FET), disposed on a semiconductor substrate, and including vertically separated first channel structures formed as thin sheets each having opposite major planar surfaces facing toward and away from the semiconductor substrate; and a second FET, disposed on the semiconductor substrate and overlapped with the first FET. A conductive type of the second FET is complementary to a conductive type of the first FET. Second channel structures of the second FET are separately arranged along a lateral direction, and formed as thin walls.
