Background technology
In the manufacture field such as quasiconductor, panel display, LED, solar energy and MEMS be micro electronmechanical, production process all can
Producing waste gas, as a example by semiconductor manufacturing, its process apparatus gas of discharge when producing can be divided into following three types: the first kind
It is flammable explosive gas, such as hydrogen (H2) or silane (SiH4);Equations of The Second Kind is toxic gas, such as nitrous oxide (N2O), chlorine
(Cl2), fluorine gas (F2);3rd class is greenhouse gases, such as carbon tetrafluoride (CF4), Nitrogen trifluoride (NF3), sulfur hexafluoride (SF6)
Etc., wherein Nitrogen trifluoride (NF3) also there is toxicity, carbon tetrafluoride (CF4) be also proved in zoopery and can destroy cell wall
Structure so that it is it is intracellular that his pollutant are easier to entrance, therefore must carry out before these gases are discharged in surrounding
Process.
At present, along with the increase of new processing procedure plant waste gases discharge capacity in recent years, the such as silicon dioxide of the by-product in production process
This kind of dust can be mingled with in the offgas, and this is accomplished by making corresponding process.Such as process apparatus is based on silane (SiH4) work
In the production of skill, the burning of combustion gas in reaction chamber needs combustion-supporting gas such as oxygen (O2), due to silane (SiH4) can be with oxygen (O2)
Produce oxidation reaction, produce silicon dioxide (SiO2), and this type of fuel gas buring emission-control equipment is for reducing oxynitride
(NOx) generation, the multistage combustion mode extensively used in many every profession and trades will be used to supply, and this kind of mode is in reaction
Chamber provides unnecessary oxygen.And too much oxygen easily produces above-mentioned reaction and causes the generation of silica dust, this dust
After entering emission-control equipment inside, can gradually block emission-control equipment inner space, owing to processing means is gradually hindered
Plug, will affect the capacity of place's process gases, the most also can form potential safety hazard.
