Abstract
A capacitor device includes a substrate, a first conductive structure, a second conductive structure, a dielectric layer structure, and a recess in the substrate. The first and second conductive structures are disposed on opposite sides of the dielectric layer structure, and the dielectric layer structure extends in a meander-shaped manner in a cross-section through the recess.
