Claim 18:
19. The method of claim 18, wherein the forming the redistribution structure comprises:
forming a first insulation layer on the first carrier to cover the planar conductive pattern;
forming a first hole in the first insulation layer, the first hole exposing a portion of the planar conductive pattern;
forming a first redistribution layer on the first insulation layer, the first redistribution layer having a first connection via in the first hole connected to the exposed portion of the planar conductive pattern;
forming a second insulation layer on the first insulation layer to cover the first redistribution layer;
forming a second hole in the second insulation layer, the second hole exposing a portion of the first redistribution layer;
forming a second redistribution layer on the second insulation layer, the second redistribution layer having a second connection via in the second hole connected to the exposed portion of the first redistribution layer; and
forming a third insulation layer on the second insulation layer to cover the second redistribution layer.
