Patent ID: 8164920

Claim:
A printed wiring board comprising: a circuit board structure having a mounting portion on which a single processor chip including a plurality of processor cores is mounted; a plurality of power supply lines formed in the circuit board structure and extending to the mounting portion of the circuit board structure such that the power supply lines are connected to the processor cores of the single processor chip, respectively; a plurality of ground lines formed in the circuit board structure and extending to the mounting portion of the circuit board structure such that the ground lines are connected to the processor cores of the single processor chip, respectively; and a plurality of independent layered capacitors positioned in the circuit board structure and connected to the power supply lines and the ground lines, respectively, such that the independent layered capacitors are connected to the processor cores of the single processor chip through the power supply lines and ground lines, respectively, wherein each of the independent layered capacitors comprises a first surface electrode, a second surface electrode and a high-dielectric layer sandwiched between the first surface electrode and the second surface electrode, one of the first surface electrode and the second surface electrode of each of the independent layered capacitors is connected to a respective one of the power supply lines and the other one of the first surface electrode and the second surface electrode is connected to a respective one of the ground lines.
