Patent ID: 11915994
Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 7:
8. A package structure, comprising:
a semiconductor die laterally wrapped by an encapsulant;
conductive vias, laterally disposed by the semiconductor die and wrapped by the encapsulant;
a thermoelectric structure, disposed on a back-side of the semiconductor die and comprising P-type semiconductor blocks, N-type semiconductor blocks, and metal pads, wherein the metal pads are disposed on a same level of the P-type semiconductor blocks and the N-type semiconductor blocks to connect the P-type semiconductor blocks and the N-type semiconductor blocks; and
a redistribution layer, disposed on the thermoelectric structure,
wherein the thermoelectric structure is configured to transfer heat generated by the semiconductor die to side walls of the package structure when a current flows through the thermoelectric structure,
wherein the metal pads are T-shaped, wherein arm portions of the adjacent T-shaped metal pads are at opposite sides of the P-type semiconductor blocks and the N-type semiconductor blocks from the top view.
