Patent ID: 7521283

Claim:
A manufacturing method of a chip integrated substrate in which a semiconductor chip is integrated, comprising: a first step that forms a wiring structure to be connected to the semiconductor chip on a first core substrate; a second step that disposes the semiconductor chip on a second core substrate; and a third step that bonds the first core substrate on which the wiring structure is formed to the second core substrate on which the semiconductor chip is disposed, wherein the first step includes: a conductive-layer forming step that forms conductive layers on the first core substrate; and a plug-wiring forming step that forms a plurality of plug wirings on one of the conductive layers, wherein the plurality of plug wirings, formed on said one of the conductive layers in the plug-wiring forming step of the first step, include first plug wirings which are connected to electrode pads of the semiconductor chip and second plug wirings which are connected to outside terminals.
