Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 13:
14. A method for forming a package structure, comprising:
forming first conductive structures and a first semiconductor die on a first side of a redistribution structure;
forming second conductive structures on the first semiconductor die;
forming an interposer substrate, wherein a first side of the interposer substrate is in contact with the first conductive structures, and the interposer substrate has a greater width than the first semiconductor die;
forming a second semiconductor die on a second side of the interposer substrate, wherein widths of the first semiconductor die and the second semiconductor die are different;
forming a first passive device element on the first side of the redistribution structure, wherein the first passive device element and the first semiconductor die have different heights; and
forming a protective layer between the first passive device element and the interposer substrate, and in contact with sidewalls of the interposer substrate, wherein the protective layer is in contact with the first semiconductor die, and is separated from the second semiconductor die by the redistribution structure.
