Patent ID: 7881069

Claim:
A printed circuit board comprising: a core substrate having at least one opening; at least one chip capacitor including a first electrode, a second electrode and a dielectric made of ceramic, the chip capacitor disposed in the opening in the core substrate; a first insulating layer formed on the core substrate; a first conductive circuit formed on the first insulating layer; a plurality of solder bumps formed on an outer surface of the printed circuit board, the plurality of solder bumps constituting a pad area on which an IC chip is to be mounted in a flip-chip manner; and first and second via contacts formed in first and second via holes, which are formed in the first insulating layer and electrically connect the first and second electrodes of the chip capacitor to the plurality of solder bumps, wherein the chip capacitor is positioned immediately below the IC chip and below the pad area constituted by the plurality of solder bumps, and an insulating bonding agent coupling the chip capacitor with the first insulating layer each other, wherein a coefficient of thermal expansion of the insulating bonding agent is lower than a coefficient of thermal expansion of said first insulating layer.
