Abstract:
1. A circuit board structure with an embedded semiconductor chip, 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 semiconductor chip having an active surface whereon a plurality of electrode pads are formed and a non-active surface, embedded in the through hole; at least one first dielectric layer made of a photosensitive material and formed on the first surface of the carrier board, with an opening in the first dielectric layer to expose the non-active surface of the semiconductor chip for heat dissipation, wherein the first dielectric layer is formed without any circuit layer; a second dielectric layer made of a photosensitive material and formed on the second surface of the carrier board and the active surface of the semiconductor chip, wherein a plurality of openings are formed in the second dielectric layer for exposing the electrode pads on the semiconductor chip; and a circuit layer formed on the second dielectric layer and electrically connected to the electrode pads on the semiconductor chip via the conductive structures in the second dielectric layer.
