Abstract: A semiconductor device is provided. The semiconductor device includes an active pattern extending in a first horizontal direction, a plurality of lower nanosheets stacked on the active pattern and spaced apart from one another in a vertical direction, a separation layer on the plurality of lower nanosheets, a plurality of upper nanosheets stacked on the separation layer and spaced apart from one another in the vertical direction, a gate electrode extending on the active pattern in a second horizontal direction, the gate electrode surrounding each of the plurality of lower nanosheets, the separation layer and the plurality of upper nano sheets, and a first conductive layer between the gate electrode and each of a top surface and a bottom surface of the plurality of upper nanosheets. The first conductive layer is not between the gate electrode and sidewalls of the plurality of upper nanosheets.

Abstract: A fan-out semiconductor package includes: a core member having a through-hole and having first fiducial marks disposed on an upper surface thereof in the vicinity of the through-hole; a semiconductor chip disposed in the through-hole and having an active surface having connection pads and second fiducial marks disposed thereon and an inactive surface opposing the active surface; an encapsulant encapsulating at least portions of the semiconductor chip; and a connection member disposed on the active surface of the semiconductor chip and including a redistribution layer electrically connected to the connection pads of the semiconductor chip, wherein the first fiducial marks are disposed to be symmetrical to each other with respect to a center of the through-hole on a plane view, and the second fiducial marks are disposed to be symmetrical to each other with respect to a center of the semiconductor chip on the plane view.
