Patent ID: 8178975

Claim:
A semiconductor package comprising: a semiconductor chip module including a first semiconductor chip and a second semiconductor chip, the first and second semiconductor chips being arranged adjacently; a first bonding pad group having a plurality of bonding pads formed in the surface of the first semiconductor chip; a second bonding pad group having a plurality of bonding pads formed in the surface of the second semiconductor chip; a re-distribution layer structure including: a first insulation member formed on the semiconductor chip module and having openings that expose each bonding pad in the first and second bonding pad groups; a plurality of coplanar first re-distribution layers arranged on the first insulation member and electrically connecting each bonding pad in the first bonding pad group to the corresponding bonding pad in the second bonding pad group; a second insulation member formed on the first insulation member to cover the first re-distribution layers, the second insulation member having a plurality of opening exposing a portion of the first re-distribution layers; second re-distribution layers arranged on the second insulation member, and each second re-distribution layer being electrically connected to the corresponding first re-distribution layer; a third insulation member formed over the second insulation member to cover the second re-distribution layers, the third insulation member having a second plurality of openings exposing the second re-distribution layer; and a plurality of pad parts, with each pad part being connected to the corresponding second re-distribution layers; and an attachment member attaching the re-distribution layer structure to the semiconductor chip module, wherein the second re-distribution layer electrically connected to the corresponding first re-distribution layer is disposed to extend from the first semiconductor chip to the second semiconductor chip and being connected to the respective pad parts of the first and the second re-distribution layers.
