A packaged integrated circuit device with a multi-level leadframe has a plurality of integral capacitors formed by placing a thin dielectric layer between a lower leadframe and an upper leadframe, one of the leadframes being subdivided into a plurality of portions, each subdivided portion with an accessible tab for wire attachment. The planar capacitors are bonded to the bottom surface of the semiconductor chip and act as a die support paddle. Each capacitor may be configured to provide the desired voltage decoupling and noise suppression for a particular portion of the integrated circuit to which it is connected. Capacitors useful for other purposes may be likewise provided in the package.
