Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 7:
8. A semiconductor structure comprising:
a die structure, the die structure comprising a first integrated circuit die encapsulated in a first encapsulant;
a second encapsulant over the die structure and the first encapsulant;
a die stack embedded in the second encapsulant, the die stack comprising a second integrated circuit die, wherein a backside of the second integrated circuit die is bonded to a backside of the first integrated circuit die;
a base structure over the die stack and embedded in the second encapsulant, the die stack being interposed between the base structure and the first integrated circuit die; and
a heat dissipation structure embedded in the second encapsulant, the heat dissipation structure being bonded to the die structure at an interface between the first integrated circuit die and the first encapsulant, wherein a top surface of the heat dissipation structure is level with a top surface of the base structure and a top surface of the second encapsulant.
