Abstract

A semiconductor device includes: a first multi-gate field effect transistor (FET) disposed over a substrate, the first multi-gate FET including a first active region; and a second multi-gate FET disposed over the first multi-gate FET, the second multi-gate FET including a second active region. The first active region and the second active region are not fully projected in a vertical direction perpendicular to the substrate.
