Patent ID: 7778038

Claim:
A device having a semiconductor device with power terminals mounted thereon, and having a power core incorporated therein, said power core comprising: a planar capacitor laminate; a layer of a prepreg; and a surface mount technology (SMT) discrete chip capacitor embedded in said prepreg layer, wherein said embedded surface mount technology (SMT) discrete chip capacitor is encapsulated within said prepreg layer, and wherein said surface mount technology (SMT) discrete chip capacitor comprises at least a first electrode and a second electrode; wherein said planar capacitor laminate serves as a low inductance path to supply a charge to said surface mount technology (SMT) discrete chip capacitor; wherein said embedded surface mount technology (SMT) discrete chip capacitor is connected in parallel to said planar capacitor laminate, and wherein said first electrode and second electrode of said surface mount technology (SMT) discrete chip capacitor are connected to at least one power terminal of the semiconductor device; and wherein said embedded surface mount technology (SMT) discrete chip capacitor is closer to power terminals of the semiconductor device than is said planar capacitor laminate.
