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

Claim 0:
1. A package structure, comprising:
a semiconductor die; and
a thermoelectric structure disposed on the semiconductor die,
wherein the thermoelectric structure comprises P-type semiconductor blocks, N-type semiconductor blocks and metal pads,
wherein the P-type semiconductor blocks and the N-type semiconductor blocks are arranged in alternation with the metal pads connecting the P-type semiconductor blocks and the N-type semiconductor blocks,
wherein when a current flowing through one of the N-type semiconductor block, one of the metal pad, and one of the P-type semiconductor block in order, the metal pad between the N-type semiconductor block and the P-type semiconductor block forms a cold junction which absorbs heat generated by the semiconductor die,
wherein when the current flowing through one of the P-type semiconductor block, one of the metal pad, and one of the N-type semiconductor block in order, the metal pad between the P-type semiconductor block and the N-type semiconductor block forms a hot junction which releases the heat absorbed by the cold junction to environment,
wherein each of the metal pads connects with two side walls of one of the P-type semiconductor blocks and connects with two side walls of one of the N-type semiconductor blocks, and the P-type semiconductor blocks and the N-type semiconductor blocks are connected through the metal pads.
