Patent ID: 7417870

Claim:
A multi-layer board having a decoupling function comprising: a board body having a plurality of stacked dielectric layers, power and ground terminals formed on upper and lower surfaces thereof, the power terminals formed on the upper and lower surfaces thereof connected with each other through a power via and the ground terminals formed on upper and lower surfaces thereof connected with each other through a ground via, and an integrated circuit component mounted on the upper surface thereof and connected to the power terminals and the ground terminals; a power line unit formed on a predetermined one of the plurality of dielectric layers of the board body, the power line unit connected to the power terminals and the integrated chip component; a ground line unit formed on a predetermined one of the plurality of dielectric layers of the board body, the ground line unit connected to the ground terminals and the integrated circuit component; at least one multilayer chip capacitor mounted on the upper surface of the board body and connected between the power terminal and the ground terminal formed on the upper surface of the board body; and at least one thin film capacitor mounted inside the board body and connected between the power line unit and the ground line unit.
