Classification: CPC H | IPC H

Claim 0:
1. A method for forming a package structure, comprising:
forming first conductive structures and a first semiconductor die on a same side of a redistribution structure;
forming an interposer substrate over the redistribution structure, wherein the first semiconductor die is between the interposer substrate and the redistribution structure, and edges of the interposer substrate extend beyond edges of the first semiconductor die;
forming a second semiconductor die on the redistribution structure, wherein the first semiconductor die and the second semiconductor die are disposed on opposite sides of the redistribution structure;
forming an interconnection structure over the interposer substrate;
forming a protective layer to be in contact with the interconnection structure, the interposer substrate, and the redistribution structure;
wherein the first semiconductor die, and the protective layer are separated from the second semiconductor die, and the protective layer extends between the first semiconductor die and the interposer substrate.
