Problems solved by technology

[0005] (1) In ESD protection devices, the ESD responsiveness tends to fluctuate due to the gap between the discharge electrodes caused by direct printing of the electrodes
In addition, although it is necessary to adjust the ESD responsiveness by the area of ​​the area where the discharge electrodes face each other, it may be difficult to achieve the desired ESD responsiveness because the adjustment is limited by the size of the product, etc.
[0006] (2) In the ESD protection device, due to thick film printing, there are certain defects in the interface of each layer, which affects the stability and reliability of the device, so the selection of materials is relatively high

Abstract

The invention discloses a ceramic ESD (electro-static discharge) suppressor and a production method thereof. The ceramic ESD suppressor made of semiconductor integrates thick film printing technique. A functional material layer provided with a frame structure is printed on an electrode cutting groove portion. As voltage greater than a set value is applied to external electrodes, electrodes at cutting clearance portions discharge mainly along the inside of the functional material layer. Since the cutting groove electrode is provided with clearances formed by points and functional slurry as loose frame structure, electrons are prone to moving, and accordingly discharge phenomenon easily occurs to improve ESD responsiveness, and ESD features are conveniently adjusted and stabled. The electrodes are printed on the surface of a ceramic substrate sintered and protected from deformation caused by sintering after cutting. A protection layer covers the ceramic substrate and functions in better protecting frame structure of the functional material layer and removing influence of moisture to the functional material layer.

Description

Technical field [0001] The invention relates to the technical field of electrostatic protection, in particular to a ceramic electrostatic suppressor and a preparation method thereof. Background technique [0002] ESD (Electro-Static Discharge) refers to the phenomenon of violent discharge when a charged conductive object (human body, etc.) is in contact with or sufficiently close to other conductive objects (electronic equipment, etc.). Electronic equipment is damaged and malfunctions due to ESD. To prevent this, it is necessary to prevent the excessive voltage generated during discharge from being applied to the circuit of the electronic device. Used for this purpose are ESD protection devices, also known as surge absorbing elements and surge absorbers. [0003] The ESD protection device is arranged, for example, between the signal line of the circuit and the ground. Since the ESD protection device adopts a structure in which a pair of discharge electrodes are separated and opp...
