Abstract:
1. A circuit board structure embedded with semiconductor chips, the circuit board structure comprising: a supporting board having at least a cavity; at least a semiconductor chip embedded in the cavity of the supporting board, the semiconductor chip having an active surface having a plurality of the electrode pads; a protection layer formed on the active surface of the semiconductor chip, the protection layer having a plurality of openings corresponding to the electrode pads for exposure of the electrode pads of the semiconductor chip; a metal layer formed on surfaces of the electrode pads exposed from the openings of the protection layer; a dielectric layer formed on the supporting board and the protection layer, the dielectric layer having another plurality of openings corresponding to the electrode pads for exposure of the metal layer on the electrode pads of the semiconductor chip; a circuit layer formed on the dielectric layer, a plurality of hollow conductive vias being formed in the another openings of the dielectric layer and electrically connected to the circuit layer, allowing the circuit layer to be electrically connected via the hollow conductive vias to the metal layer on the electrode pads of the semiconductor chip; and a circuit build-up structure formed on the dielectric layer and the circuit layer, a plurality of fully-plated metal vias being formed in the circuit build-up structure, an electrical conductive pad being formed on the circuit build-up structure, wherein a portion of the fully-plated metal vias are electrically connected to the circuit layer, and rest of the fully-plated metal vias are extended to a bottom portion of the hollow conductive vias of the circuit layer.
