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

Claim 11:
12. The package structure of claim 8, wherein the current flows from a first semiconductor block to a second semiconductor block through the metal pad in the thermoelectric structure,
wherein when the first semiconductor block is the N-type semiconductor block and the second semiconductor block is the P-type semiconductor block, the metal pad is a cold junction with the arm portion of the metal pad facing an interior of the package structure and absorbing the heat generated by the semiconductor die,
wherein when the first semiconductor block is the P-type semiconductor block and the second semiconductor block is the N-type semiconductor block, the metal pad is a hot junction with the arm portion of the metal pad facing an exterior of the package structure and releasing the heat absorbed from the arm portion of the cold junction to environment.
