Process for fabricating chip embedded package structure

A process for fabricating a chip embedded package structure, comprising:

• disposing a stiffener on a tape, wherein the tape has at least a first alignment mark and at least a second alignment mark which are located on the both sides of the tape respectively, and the stiffener has at least a chip opening;
• disposing a chip on the tape inside the chip opening such that an active surface of the chip faces the tape, wherein the chip also comprises a plurality of bonding pads disposed on the active surface;
• forming a plurality of through holes passing the tape and exposing the bonding pads respectively, wherein the through holes are formed in the tape by using the second alignment mark as a positioning reference;
• depositing conductive material into the though holes to form a plurality of conductive vias which are connected to the bonding pads respectively;
• and
• forming a multi-layered interconnection structure on the tape on the opposite of the chip by using the first alignment mark as a positioning reference, wherein the multi-layered interconnection structure comprises an inner circuit which is connected to the conductive vias, and the inner circuit has a plurality of metallic pads on a surface of the multi-layered interconnection structure away from the tape.
