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

Claim 14:
15. A semiconductor structure comprising:
a die structure, the die structure comprising a first integrated circuit die encapsulated in a first encapsulant;
a die stack attached to the first integrated circuit die, the die stack comprising a bottommost integrated circuit die, a backside of the bottommost integrated circuit die facing a backside of the first integrated circuit die;
a second encapsulant over the first integrated circuit die and extending along sidewalls of the die stack, wherein a top surface of the second encapsulant is level with a top surface of the die stack;
a base structure attached to the die stack and the second encapsulant, a width of the base structure being greater than a width of the die stack;
a heat dissipation structure attached to the die structure adjacent to the die stack; and
a third encapsulant over the die structure and extending along sidewalls of the base structure, sidewalls of the heat dissipation structure, and sidewalls of the second encapsulant, wherein a sidewall of the third encapsulant is coplanar with a sidewall of the first encapsulant.
