Technical field
The utility model is related to protect field of circuit technology, especially a kind of ESD device structure.
Background technology
In general, various electrical equipments can be more fragile to static discharges such as surges, in the case, ESD can be used
(Electro-Static-Discharge：Static discharge) protect structure to protect influence of the circuit element from static discharge.
In order to protect circuit element from electrostatic influence, esd protection structure is to be drawn excessive voltage from signal wire using electric discharge phenomena
Lead the structure of ground connection.
Currently, it as the device with esd protection structure, is developing a kind of empty in the setting of the inside of glass ceramic baseplate
Hole portion, will be respectively with signal wire and the discharge electrode that is connected of ground connection to being oppositely disposed in blank part and by particle shape
Discharge-assisted electrode is distributed the device between discharge electrode pair (for example, referring to patent document 1).In the device architecture,
In the case where applying excessive voltage to signal wire, the electric discharge via discharge-assisted electrode occurs between discharge electrode pair, it is quiet
Electricity is directed into ground connection.
Therefore, for the above problem, it is necessary to propose the analysis system of sign data.
