Claim:
1. A method of assembling a packaged semiconductor device comprising a first substrate and a second substrate, at least one integrated circuit die on said first substrate, and at least one chip capacitor die having first and second capacitor plates coupled to said integrated circuit die on said first substrate, said first substrate having electrically conductive contact regions thereon, comprising: dropping a pre-formed capacitor precursor on a surface of said first substrate; dropping said integrated circuit die on either of said first substrate; if said pre-formed capacitor precursor lacks at least a first pair of vias for providing an electrical contact between capacitor plates of said chip capacitor, following said dropping said pre-formed capacitor precursor, forming at least a first pair of vias in said pre-formed capacitor precursor; filling said first pair of vias with an electrically conductive material to form said chip capacitor, wherein said filling of said vias provides an electrical contact between said first and second capacitor plates of said chip capacitor and said electrically conductive contact regions on said first substrate; and alternating stacking a plurality of electrically conductive material layers and a plurality of dielectric layers on said second substrate, said plurality of electrically conductive material layers comprising first and second patterns, wherein said first patterns each comprise at least a first pair of overlaying areas free of said electrically conductive material, and said second patterns each comprise at least a second pair of overlaying areas free of said electrically conductive material, wherein said first pair of areas overlay areas of said second pattern having said electrically conductive material and said second pair of areas overlay areas of said first pattern having said electrically conductive material, and wherein said plurality of electrically conductive material layers are electrically isolated from one another by said dielectric layers.
