Patent ID: 7485966

Claim:
A via connection structure suitable for a multi-layer substrate which comprises a plurality of conductive layers and a plurality of insulation layers alternately stacked, comprising: a first conductive line disposed on a first conductive layer; a second conductive line disposed on a second conductive layer; at least a reference plane disposed between the first conductive layer and the second conductive layer, and having at least a clearance which is a first non-conductive area; a via connection structure electrically connected to the first conductive line and the second conductive line having at least one conducting via passing through the conductive layers, insulation layers and the clearance of the reference plane; and at least a compensative area, which is a second non-conductive area on the reference plane, wherein the compensative area is adjacent to the clearance and is overlapped with a portion of the region where the conductive line projects on the adjacent reference plane.
