Abstract
An integrated circuit (IC) device includes an IC and an electrostatic discharge (ESD) protection device. The IC has a substrate, a core and a power mesh. The power mesh has a power electrode, a grounding electrode and a seal ring. The core is formed inside the grounding electrode. The power electrode is formed between the seal ring and the grounding electrode. The ESD protection device has multiple switch triggering units, multiple switching units and multiple discharging units formed on the substrate and electrically connected between the power electrode and the grounding electrode. The switching units turn on corresponding discharging units upon detecting occurrence of ESD to guide static electricity on the power electrode to the grounding electrode, thereby preventing the core from being damaged by static electricity.
