Claim 18:
19. An integrated circuit device comprising:
a substrate comprising:
a first device region; and
a second device region disposed apart from the first device region;

a first fin-type active region extending in a first horizontal direction in the first device region;
a second fin-type active region extending in the first horizontal direction in the second device region;
a first nanosheet stack comprising at least one first nanosheet facing a first fin top surface of the first fin-type active region and disposed apart from the first fin top surface in a vertical direction;
a second nanosheet stack comprising at least one second nanosheet facing a second fin top surface of the second fin-type active region and disposed apart from the second fin top surface in the vertical direction;
a gate line comprising:
a connection protrusion portion extending in a second horizontal direction intersecting the first horizontal direction, in the first device region and the second device region, the connection protrusion portion comprising a protrusion top surface at a first vertical level from the substrate;
a main gate portion comprising a recess top surface extending in the second horizontal direction from the connection protrusion portion, the recess top surface being at a second vertical level lower than the first vertical level; and
a plurality of sub gate portions connected to the main gate portion as one body and surrounding the first nanosheet stack and the second nanosheet stack;

a gate contact disposed on the gate line and contacting the connection protrusion portion;
a source/drain region disposed on one among the first fin-type active region and the second fin-type active region and disposed adjacent to the gate line; and
a source/drain contact disposed on the source/drain region, the source/drain contact comprising an uppermost surface at a third vertical level higher than the first vertical level.
