Patent ID: 8441116

Claim:
A semiconductor package comprising: a sub-semiconductor package including semiconductor chips and a sub-substrate, the semiconductor chips comprising: a first semiconductor chip which has first bonding pads facing a first surface of the sub-substrate; and a second semiconductor chip which has second bonding pads facing a second surface of the sub-substrate, wherein the second bonding pads are formed to directly correspond and align with the first bonding pads; the sub-substrate comprising: a sub-substrate body having a first surface and a second surface on the opposite side of the first surface wherein the sub-substrate body is interposed between the first and second bonding pads a plurality of sub-connection pads formed along a first edge of the first surface of the sub-substrate body; a plurality of signal lines, each signal line comprising: a first line part formed on the first surface of the sub-substrate body and connected to a sub-connection pad; a conductive via connected to the first line part and passing through the sub-substrate body; a second line part formed on the first surface of the sub-substrate body connected to a first bonding pad and the conductive via; and a third line part formed on the second surface of the sub-substrate body connected a second bonding pad and the conductive via; a power line formed such that a first portion of the power line extends laterally along a second edge of the first surface of the sub-substrate body which is adjacent and connected to the first edge of the first surface of the sub-substrate body, a second portion of the power line extends laterally along a third edge of the first surface of the sub-substrate body opposite the second edge, and a third portion of the power line connects the first portion of the power line and the second portion of the power line such that the power line has an “H” shape; and a main substrate supporting the sub-semiconductor package and having connection pads which are connected to the sub-connection pads.
