Patent ID: 7754538

Claim:
A method for manufacturing a packaging substrate structure with electronic components embedded therein, comprising: providing a core board; forming a built-up structure on at least one surface of the core board, wherein the built-up structure comprises at least one dielectric layer, at least one wiring layer stacked on the dielectric layer, and a plurality of conductive vias electrically connecting to the wiring layer, the built-up structure has an electronic component-disposing part on the surface thereof, and the outmost wiring layer of the built-up structure has a plurality of conductive pads and a metal block on the electronic component-disposing part; forming a solder mask on the surface of the built-up structure, wherein a plurality of openings are formed in the solder mask to expose the conductive pads of the built-up structure, also a first open area is formed in the solder mask to expose the metal block, and a second open area is formed by etching the metal block; and placing an electronic component in the first and second open areas, wherein the electronic component has an active surface and an inactive surface, the active surface has a plurality of electrode pads, and the inactive surface faces the electronic component-disposing part of the built-up structure.
