Patent ID: 7847404

Claim:
A packaged integrated circuit device comprising: a semiconductor die; a plurality of decoupling capacitors, the plurality of decoupling capacitors including a first decoupling capacitor and a third decoupling capacitor that extend on one side of the semiconductor die, and a second decoupling capacitor and a fourth decoupling capacitor that extend on the opposite side of the semiconductor die; a package substrate that includes a first grid array of contact pads that are electrically coupled to corresponding contact pads on the semiconductor die, the first grid array of contact pads including a first set of adjacent rows or columns of contact pads, all of the contact pads in the first set of adjacent rows or columns of contact pads coupled to a first channel of contiguous metallization that extends within a ground plane of the package substrate, a second set of adjacent rows or columns of contact pads, all of the contact pads in the second set of adjacent rows or columns of contact pads electrically coupled to a second channel of contiguous metallization that extends within a power plane of the package substrate and a third set of adjacent rows or columns of contact pads, all of the contact pads in the third set of adjacent rows or columns of contact pads coupled to a third channel of contiguous metallization that extends within a ground plane of the package substrate, all of the contact pads in the first set of adjacent rows or columns of contact pads directly overlying a portion of the first channel, all of the contact pads in the second set of adjacent rows or columns of contact pads directly overlying a portion of the second channel and all of the contact pads in the third set of adjacent rows or columns of contact pads directly overlying a portion of the third channel; and wherein the first decoupling capacitor is electrically coupled to the first channel and the second channel proximate one end of the first channel and the second channel, and a the second decoupling capacitor is electrically coupled to the first channel and the second channel proximate an opposite end of the first channel and the second channel, the third decoupling capacitor is electrically coupled to the second channel and is electrically coupled to the third channel proximate one end of the third channel, and the fourth decoupling capacitor is electrically coupled to the third channel proximate an opposite end of the third channel, the first channel, the second channel and the third channel extending contiguously between the first decoupling capacitor and the second decoupling capacitor and the third channel extending contiguously between the third decoupling capacitor and the fourth decoupling capacitor.
