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

Claim 0:
1. A semiconductor structure comprising:
a die embedded in a molding material, the die having die connectors at a front side of the die;
a conductive pillar laterally adjacent to the die and embedded in the molding material;
a first redistribution structure over the molding material at a backside of the die, the conductive pillar being electrically coupled to the first redistribution structure; and
a heat dissipation structure embedded in the first redistribution structure, wherein the heat dissipation structure extends through the first redistribution structure and is attached to the backside of the die, wherein the heat dissipation structure comprises:
dummy metal patterns embedded in dielectric layers of the first redistribution structure; and
a metal paste extending through the first redistribution structure and contacting the dummy metal patterns.
