A semiconductor device includes a first gate electrode provided in a jumper region of a substrate and extending in a first direction, first source/drain regions provided at both sides of the first gate electrode, and a connecting contact electrically connecting the first gate electrode and the first source/drain regions to each other. The connecting contact includes first sub-contacts disposed at both sides of the first gate electrode and connected to the first source/drain regions, and a second sub-contact extending in a second direction intersecting the first direction. The second sub-contact is connected to the first sub-contacts and is in contact with a top surface of the first gate electrode. In the first direction, each of the first sub-contacts has a first width and the second sub-contact has a second width smaller than the first width.
