Patent ID: 11942441
Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 8:
9. A semiconductor device, comprising:
a through-silicon via (TSV) extending through a substrate and a TSV zone of a semiconductor device interconnect structure;
a set of ESD cells in proximity to a first side of the substrate, wherein the set of ESD cells extend around a circumference of the TSV, and wherein each ESD cell of the set of ESD cells comprises a set of diodes electrically connected in parallel, and wherein a first end of the TSV is at a different side of the substrate from the set of ESD cells, and a second end of the TSV is at the same side of the substrate from the set of ESD cells;
a set of conductive pillars, wherein a first end of each conductive pillar electrically connects to one ESD cell, and a second end of each conductive pillar is proximal to the second end of the TSV;
an antenna pad, wherein the antenna pad
is proximal to the second end of the TSV,
electrically connects to the second end of the TSV, and
electrically connects to conductive pillars of the set of conductive pillars; and

a set of antennas extending through the TSV zone parallel to the TSV and electrically connected to the antenna pad.
