Abstract
An integrated circuit device includes a first-type transistor having a channel region in a first-type active-region semiconductor structure and a second-type transistor having a channel region in a second-type active-region semiconductor structure which is stacked with the first-type active-region semiconductor structure. In the integrated circuit, a front-side power rail and a front-side signal line in a front-side conductive layer extend in the first direction is, and a back-side power rail and a back-side signal line in a back-side conductive layer also extend in the first direction. The front-side conductive layer is above the first-type active-region semiconductor structure and the second-type active-region semiconductor structure, while the back-side conductive layer is below the first-type active-region semiconductor structure and the second-type active-region semiconductor structure.
