Abstract:
The present disclosure relates to a semiconductor device and a manufacturing method, and more particularly to a MIM dual capacitor structure with an increased capacitance per unit area in a semiconductor structure. Without using additional mask layers, a second parallel plate capacitor can be formed over a first parallel plate capacitor, and both capacitors share a common capacitor plate. The two parallel plate capacitors can be connected in parallel to increase the capacitance per unit area.

Claim (Index 1):
A semiconductor structure comprising:\n a substrate; a first metal layer formed over the substrate; a first dielectric layer formed over the first metal layer; a second metal layer formed over the first dielectric layer, wherein a surface area of the second metal layer is less than a surface area of the first metal layer; a second dielectric layer formed over the second metal layer; a third metal layer formed over the second dielectric layer, wherein a surface area of the third metal layer is less than the surface area of the second metal layer; and one or more interconnect structures electrically connected to the first and third metal layers.
