Patent ID: 7973397

Claim:
A packaging substrate having an embedded semiconductor chip, comprising: a core board having a first surface and an opposite second surface, and a through cavity penetrating the first and second surfaces; the embedded semiconductor chip disposed in the through cavity and having an active surface and an opposite inactive surface, the active surface having a photosensitive portion and a plurality of electrode pads and being at a same side as the first surface of the core board, while the inactive surface being at a same side as the second surface of the core board; a first dielectric layer formed on the active surface and the first surface of the core board, the first dielectric layer having a light-permeable window to expose the photosensitive portion of the embedded semiconductor chip; a first circuit layer formed on the first dielectric layer and having a plurality of first conductive vias disposed in the first dielectric layer for electrically connecting to the electrode pads; a second dielectric layer formed on the inactive surface and the second surface of the core board; a second circuit layer formed on the second dielectric layer; and a plurality of conductive through holes penetrating the core board and the first and second dielectric layers, and electrically connecting the first and second circuit layers.
