Patent ID: 7839649

Claim:
A circuit board structure having an embedded semiconductor element, comprising: a carrier board having a first surface, a second surface, and at least one through hole penetrating the carrier board from the first surface to the second surface; a first semiconductor element received in the through hole and having an active surface and an inactive surface, the active surface of the first semiconductor element having a plurality of electrode pads; at least one second semiconductor element mounted on a surface of the carrier board and having an active surface and an inactive surface, the active surface of the second semiconductor element having a plurality of electrode pads, and the second semiconductor element being mounted on the second surface of the carrier board via the inactive surface of the second semiconductor element; a first encapsulation layer formed on the first surface of the carrier board to block one end of the through hole of the carrier board; a second encapsulation layer formed on the second surface of the carrier board and the second semiconductor element, wherein the first and the second encapsulation layers integrate with one another and fill the through hole of the carrier board, so as to secure the first semiconductor element to the through hole and expose the electrode pads; and a circuit build-up structure formed on a surface of the second encapsulation layer, wherein the circuit build-up structure has a plurality of conductive structures for electrical connection with the electrode pads of the first semiconductor element and the electrode pads of the second semiconductor element.
