Abstract:
Disclosed herein is a device comprising a first redistribution layer (RDL) having first lands disposed on a bottom surface of the first RDL and active contact pads disposed on a top surface of the first RDL. The first RDL electrically connects the first lands to the active contact pads. A molding compound layer is disposed on the top surface of the first RDL. Active vias extend through the molding compound layer and are in electrical contact with the active contact pads. Dummy vias extending through the molding compound layer. Top surfaces of the active vias and top surfaces of the dummy vias are substantially planar with a top surface of the molding compound layer, and the dummy vias are electrically insulated from the active vias and the first lands.
