Problems solved by technology

[0002] Electrostatic discharge (ESD, Electrostatic Discharge) is one of the main problems in the connection process of electronic equipment. It will cause many electronic components or electronic systems to fail, causing electronic equipment manufacturers to suffer a lot of losses.
In addition, multi-functionality and miniaturization have become the current design trend of handheld products. However, when these handheld products are required to provide multi-functions, their I / O ports will also increase, which will easily cause ESD to enter the system, and then interfere or damage the integration. circuit

Abstract

The invention discloses an electrostatic discharging (ESD) protection device and a protection method thereof. A plurality of crystal particles are provided, each crystal particle is provided with a first electric connecting pad, the first electric connecting pad is electrically connected with a sealing ring which forms a border of the crystal particle, and a second electric connecting pad is electrically connected with a second electric connecting pad so as to achieve the effect of protecting the electrostatic discharging.

Description

technical field [0001] The invention relates to a device for protecting electrostatic discharge on a wafer and a protection method thereof, in particular to an ESD protection device and a protection method thereof. Background technique [0002] Electrostatic discharge (ESD, Electrostatic Discharge) is one of the main problems in the connection process of electronic equipment. It will cause many electronic components or electronic systems to fail, causing electronic equipment manufacturers to suffer a lot of losses. In addition, multi-functionality and miniaturization have become the current design trend of handheld products. However, when these handheld products are required to provide multi-functions, their I / O ports will also increase, which will easily cause ESD to enter the system, and then interfere or damage the integration. circuit. [0003] The reason for the destruction of ESD is that in addition to human factors, the electronic components themselves will also accu...
