Abstract
An apparatus is provided. In the apparatus, there is comprises a substrate with a first region of a first conductivity type, a second region of a second conductivity type that is substantially surrounded by the first region, and a third region of the second conductivity type that is substantially surrounded by the second region. A first dielectric layer is formed over the substrate, and a first conductive layer is formed over the first dielectric layer, which is configured to form a first electrode of a capacitor. A second dielectric layer is formed over the first conductive layer. A plate is formed over the second dielectric layer so as to form a second electrode of the capacitor. A cap is formed over the second dielectric layer, being spaced apart from the plate. A via is electrically coupled to the cap and the third region, extending through the first and second dielectric layers.
