Patent ID: 8377506

Claim:
A method of manufacturing substrate structure, comprising: providing a substrate, wherein the substrate having a first circuit pattern layer and a second circuit pattern layer is formed on two opposite surfaces of the substrate respectively; forming a first insulation layer on the first circuit pattern layer, wherein the first insulation layer has a first insulation hole, which exposes a first opening in the outer surface of the first insulation layer and exposes a part of the first circuit pattern layer; forming a second insulation layer on the second circuit pattern layer, wherein the second insulation layer has a second insulation hole; forming a first seed layer on the second insulation layer and simultaneously forming a second seed layer on the first insulation layer; completely removing the second seed layer; and after removing the second seed layer, forming a conductive part on the first insulation hole and simultaneously forming a conductive layer on the first seed layer, wherein the conductive part for electrically connecting with a chip is enclosed by the edge of the first opening, the part of the first circuit pattern layer contacts the conductive part, and the conductive layer is used for electrically connecting with a circuit board.
