Abstract
A semiconductor () has an active device, such as a transistor, with a directly underlying passive device, such as a capacitor (), that are connected by a via or conductive region () and interconnect (). The via or conductive region () contacts a bottom surface of a diffusion or source region () of the transistor and contacts a first () of the capacitor electrodes. A laterally positioned vertical via () and interconnect () contacts a second () of the capacitor electrodes. A metal interconnect or conductive material () may be used as a power plane that saves circuit area by implementing the power plane underneath the transistor rather than adjacent the transistor.
