SEMICONDUCTOR PACKAGE AND METHOD OF MANUFACTURING THE SAME

A semiconductor package includes a base substrate. An interposer substrate includes a plurality of interposer redistribution structures sequentially stacked in a vertical direction and an interposer insulation layer. The plurality of interposer redistribution structures includes a plurality of conductive interposer patterns and a plurality of conductive interposer vias. A semiconductor chip is disposed between the base substrate and the interposer substrate and is attached on the base substrate. A plurality of conductive connection pads is respectively disposed on a plurality of uppermost conductive interposer patterns of an uppermost interposer redistribution structure of the plurality of interposer redistribution structures. The interposer insulation layer includes a plurality of pad holes exposing at least a portion of each of an upper surface of a corresponding uppermost conductive interposer pattern of the plurality of uppermost conductive interposer patterns.
