Patent ID: 7705423

Claim:
A device with a package that provides a low noise power supply to an integrated circuit comprising: a plurality of prepreg layers, at least one patterned metal layer built over one of said prepreg layers, a semiconductor die having input/output power supply terminals electrically connected to one of said at least one patterned metal layer, a layer of discrete ceramic capacitors embedded between two of said prepreg layers, each of said discrete ceramic capacitors in said layer comprising a dielectric between opposing electrodes, the electrodes of said discrete ceramic capacitors being electrically connected to one of said at least one patterned metal layer by conductive vias formed through at least one prepreg layer, said layer of discrete ceramic capacitors including a first array of discrete ceramic capacitors wherein the discrete ceramic capacitors of said first array are located within the perimeter of the shadow of the semiconductor die or partially within the perimeter of the shadow of the semiconductor die, and wherein the first array of discrete ceramic capacitors includes capacitors having electrodes of multiple shapes and sizes, includes capacitors having electrodes with different numbers of vias and arrangements of vias interconnecting the capacitor electrodes to one of said at least one patterned metal layer, and includes capacitors having different resonance frequencies.
