Abstract
An integrated circuit device is provided. The integrated circuit device includes: a substrate with a first active area and a second active area spaced apart from each other in a first horizontal direction; a plurality of normal cells arranged on a first surface of the substrate; a power wiring structure arranged on a second surface of the substrate; and a power gating cell arranged on the first surface of the substrate. The power gating cell includes: a sleep control transistor arranged in the first active area; and a through via penetrating the second active area of the substrate. The power gating cell is configured to provide a virtual power voltage to the plurality of normal cells through a virtual power line based on a power voltage supplied from the power wiring structure through the through via and a power line.
