Abstract:
A semiconductor package has a capacitor die and a packaging substrate. The capacitor die is coupled to circuitry on a front or back side of a die coupled to the packaging substrate for providing decoupling capacitance. In one example, the capacitor die is coupled to a land side of the packaging substrate in an area depopulated of a packaging array and adjacent to the packaging array. In another example, the capacitor die may be stacked on the die and coupled through wire bonds to circuitry on the die. The capacitor die reduces impedance of the integrated circuit allowing operation at higher frequencies.
Abstract:
A semiconductor packaging system has a packaging substrate into which inductors and/or capacitors are partially or completely embedded. An active portion of a voltage regulator is mounted on the packaging substrate and supplies regulated voltage to a die also mounted on the packaging substrate. Alternatively, the active portion of the voltage regulator is integrated into the die the voltage regulator supplies voltage to. The voltage regulator cooperates with the inductors and/or capacitors to supply voltage to the die. The inductors may be through vias in the packaging substrate. For additional inductance, through vias in a printed circuit board on which the packaging substrate is mounted may couple to the through vias in the packaging substrate.

A system and method for expanding a chassis network using soft interconnects, including a hybrid chassis 500 comprising a first fabric card 560 comprising a first switching fabric 565, a second fabric card 570 comprising a second switching fabric 575, a first set of line cards 510-520 coupled to the first switching fabric 560 via a first set of hard connections (solid arrowheads), and coupled to an interface 576 associated with the second switching fabric 575 via a soft connection 580, and a second set of line cards 530-540 coupled to the second fabric card 570.
Abstract:
A stacked integrated circuit includes a first tier IC and a second tier IC. Active faces of the first tier IC and the second tier IC face each other. An interconnect structure, such as microbumps, couples the first tier IC to the second tier IC. An active portion of a voltage regulator is integrated in the first semiconductor IC and coupled to passive components (for example a capacitor or an inductor) embedded in a packaging substrate on which the stacked IC is mounted. The passive components may be multiple through vias in the packaging substrate providing inductance to the active portion of the voltage regulator. The inductance provided to the active portion of the voltage regulator is increased by coupling the through via in the packaging substrate to through vias in a printed circuit board that the packaging substrate is mounted on.
Abstract:
An integrated circuit package includes a decoupling capacitor. The integrated circuit package also includes a packaging substrate. The decoupling capacitor is at least partially embedded in the packaging substrate. The integrated circuit package further includes a die mounted to the packaging substrate. The die is coupled to the decoupling capacitor. The die receiving substantially instantaneous current from the decoupling capacitor.
