1. An integrated circuit comprising:
a plurality of standard cells spaced apart from each other in a first direction; and
a plurality of filler cells arranged between the plurality of standard cells,
wherein at least one of the plurality of filler cells comprises:
a first active region extending in the first direction and having a first width; and
a second active region of a different type from that of the first active region, the second active region being spaced apart from the first active region in a second direction perpendicular to the first direction and extending in the first direction, wherein at least one of the plurality of standard cells comprises:
a third active region of a same type as that of the first active region, the third active region being adjacent to the first active region in the first direction, extending in the first direction, and having a second width which is less than the first width;
a fourth active region of a same type as that of the second active region, the fourth active region being spaced apart from the third active region in the second direction and extending in the first direction; and
a first tapering portion of the same type as that of the first active region, the first tapering portion comprising a first contact surface contacting the first active region in the first direction, a second contact surface contacting the third active region in the first direction, and an inclination surface connecting the first contact surface to the second contact surface and having an inclination.
