Abstract
A semiconductor device includes a substrate wafer and having a front face and a back face. A front hole is formed in the front face and a multilayer capacitor is formed in the front hole. A back hole is formed in the back face of the substrate wafer to expose at least a portion of the multilayer capacitor. A front electrical connection on the front face and a back electrical connection in the back hole are used to make electrical connection to first and second conductive plates of the multilayer capacitor which are separated by a dielectric layer. The front hole may have a cylindrical shape or an annular shape.
