Patent ID: 11961834
Assignee: TAIWAN SEMICONDUCTOR MANUFACTURING COMPANY LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A semiconductor device, comprising:
a first diode having a plurality of first doped straps that extend in a first direction and configured as a plurality of terminals coupled to a first voltage terminal; and
a second diode having a second doped strap that extends in the first direction and is separated from the plurality of first doped straps in a second direction different from the first direction, wherein the second diode further comprises a plurality of third doped straps that are coupled to a second voltage terminal having a higher voltage level than that of the first voltage terminal,
wherein the second doped strap is configured as a first terminal of the second diode to be coupled to an input/output (I/O) pad,
wherein the first diode and the second diode include a first semiconductor structure configured to operate as a first equivalent silicon controlled rectifier circuit between the I/O pad and the first voltage terminal.
