Abstract
The present disclosure generally relates to a capacitor on an integrated circuit (IC) die. In an example, a package includes first and second IC dice. The first IC die includes a first circuit, a capacitor, and a polyimide layer. The first circuit is on a substrate. The capacitor includes a bottom plate over the substrate and a top plate over the bottom plate. The polyimide layer is at least partially over the top plate. A distance from a top surface of the top plate to a bottom surface of the polyimide layer is at least 30% of a distance from a top surface of the bottom plate to a bottom surface of the top plate. A signal path, including the capacitor, is electrically coupled between the first circuit and a second circuit in the second IC die, which does not include a galvanic isolation capacitor in the signal path.
