Claim 0:
1. A method of manufacturing a semiconductor package, the method comprising:
forming a first redistribution layer on a first carrier;
forming a redistribution structure on the first carrier to cover the first redistribution layer, wherein the redistribution structure includes a plurality of insulation layers and a plurality of second redistribution layers respectively disposed between the plurality of insulation layers, each of the plurality of second redistribution layers having a connection via connected to an adjacent one of the first redistribution layer and the plurality of second redistribution layers;
forming a plurality of bonding pads on the redistribution structure, each of the plurality of bonding pads having a bonding via connected to an uppermost redistribution layer among the plurality of second redistribution layers;
mounting at least one semiconductor chip having a plurality of contact pads on the redistribution structure such that the plurality of contact pads are connected to the plurality of bonding pads, respectively;
attaching a second carrier to an upper surface of the at least one semiconductor chip;
removing the first carrier from a surface of the redistribution structure, in which the first redistribution layer is disposed;
forming a base insulation layer on the surface of the redistribution structure to cover the first redistribution layer; and
forming an underbump metallurgy (UBM) pad on the base insulation layer, the UBM pad having a UBM via connected to the first redistribution layer.
