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

Claim 9:
10. A semiconductor structure, comprising:
a functional die on a first surface, the functional die comprising a first substrate and a first insulating layer on the first substrate;
a first dummy die on the first surface, the first dummy die comprising a second substrate and a second insulating layer on the second substrate, wherein the first insulating layer and the second insulating layer face a same direction relative to the first surface;
a molding material on the first surface, the molding material extending between the first dummy die and the functional die, wherein the molding material completely covers sidewalls of the second insulating layer; and
a redistribution structure over the functional die and the molding material, wherein the redistribution structure comprises an external contact electrically coupled to the functional die, wherein the molding material extends between the first dummy die and the redistribution structure.
