Abstract
An integrated capacitor includes a semiconductor substrate. A first vertical plate is laid over the semiconductor substrate. The first vertical plate consists of a plurality of first conductive slabs connected vertically using multiple first via plugs. A second vertical plate is laid over the semiconductor substrate in parallel with the first vertical plate. The second vertical plate consists of a plurality of second conductive slabs connected vertically using multiple second via plugs. A conductive plate is laid under the first vertical plate and second vertical plate over the semiconductor substrate for shielding the first vertical plate from producing a plate-to-substrate parasitic capacitance thereof. The second vertical plate is electrically connected with the conductive plate using a third via plug.
