Classification: CPC H | IPC H

Claim 15:
16. A method comprising:
forming a first redistribution structure over a carrier;
directly bonding an interconnect die and a passive device die to the first redistribution structure, the interconnect die being free of transistors;
dispensing a first underfill between the interconnect die and the passive device;
dispensing an insulating material around the interconnect die, the passive device, and the first underfill;
forming a second redistribution structure over the insulating material, the interconnect die, and the passive device, the second redistribution structure being electrically connected to the interconnect die;
removing the carrier; and
directly bonding a first device die and a second device die to an opposite side of the first redistribution structure as the interconnect die and the passive device die, the first device die being electrically connected to the second device die through the interconnect die.
