Patent ID: 8436463

Claim:
A packaging substrate structure with an electronic component embedded therein, comprising: a core board; a first built-up structure disposed on at least one surface of the core board, and comprising at least one first dielectric layer, at least one first wiring layer disposed on the first dielectric layer, and a plurality of first conductive vias disposed in the first dielectric layer and electrically connecting with the first wiring layer; a second built-up structure disposed on the surface of the first built-up structure and having a metal block penetrating through the second built-up structure, wherein the metal block has a cavity to expose the first built-up structure and the second built-up structure comprises at least one second dielectric layer, at least one second wiring layer disposed on the second dielectric layer, and a plurality of second conductive vias disposed in the second dielectric layer and electrically connecting with the second wiring layer, therewith the outmost second wiring layer having a plurality of conductive pads; an electronic component disposed in the cavity and having an active surface and an inactive surface, wherein the active surface has a plurality of electrode pads, and the inactive surface faces the first built-up structure; and a solder mask disposed on the surfaces of the second built-up structure and the electronic component, wherein the solder mask has a plurality of first openings to expose the electrode pads of the electronic component and further has a plurality of second openings such that the conductive pads of the second built-up structure are not covered by the solder mask.
