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

Claim 11:
12. A method of forming a semiconductor structure, the method comprising:
attaching a first die and a second die to a carrier;
forming a first molding material on the carrier around the first die and the second die;
bonding a first interposer to the first die and the second die, wherein the first die and the second die are interposed between the first interposer and the carrier;
bonding a second interposer to the second die;
forming an underfill material between the first die and the first interposer, and between the second die and the second interposer;
forming a second molding material over the first molding material around the first interposer, the second interposer, and the underfill material, wherein the second molding material contacts and extends along sidewall of the underfill material, wherein the second molding material contacts and extends along an upper surface of the first molding material distal from the carrier; and
forming a redistribution structure over the second molding material, the first interposer, and the second interposer, wherein a conductive line of the redistribution structure extends continuously from the first interposer to the second interposer.
