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

Claim 15:
16. A semiconductor structure, comprising:
a functional die on a first surface of a first structure, the functional die comprising a first substrate and a first insulating layer on the first substrate, wherein the first substrate is interposed between the first structure and the first insulating layer;
a first dummy die on the first surface of the first structure laterally spaced apart from the functional die, the first dummy die comprising a second substrate and a second insulating layer on the second substrate, wherein the second substrate is interposed between the first structure and the second insulating layer;
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 on the functional die, the first dummy die, and the molding material, wherein the redistribution structure comprises an external contact electrically coupled to the electrical contact of the functional die, wherein the redistribution structure contacts the first insulating layer and the second insulating layer.
