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

Claim 0:
1. A package structure, comprising:
a first conductive feature structure;
a second conductive feature structure over the first conductive feature structure;
a die, between the first conductive feature structure and the second conductive feature structure, wherein the die is electrically connected to the second conductive feature structure;
an insulator, disposed between the die and the first conductive feature structure, wherein the insulator has a bottom surface in physical contact with a polymer layer of the first conductive feature structure;
an adhesive layer, disposed between the die and the insulator;
an encapsulant, between the first conductive feature structure and the second conductive feature structure, wherein the encapsulant is disposed on the insulator and laterally encapsulates the die and the insulator; and
a first through via, extending through the encapsulant to connect to the first conductive feature structure and the second conductive feature structure,.
wherein the insulator comprises a coefficient of thermal expansion lager than a coefficient of thermal expansion of the die and less than a coefficient of thermal expansion of the encapsulant.
