Purification plant's main role is to control products (such as silicon chips, etc.) in contact with the atmosphere of cleanliness and temperature and humidity, so that products can in a good environment space of production, manufacture, this space we call purification plant. According to international practice, clean purification level is mainly based on the particle diameter is larger than the number of particles per cubic meter of air division standards prescribed in the past. That is not the so-called 100% clean with no dirt, but to control in a very small amount of units. Of course, in line with the dust particles of the standard criteria with respect to our common dust is already a little small, but for the optical structure is concerned, even a little bit of dust will have a very large negative impact, so in the production of optical structure on purification plant dust is inevitable requirement. Purification plant will be less than 0.3 microns per cubic meter of particle number in 3500 following dust control, dust reached the international standard of A-level. Currently purification plant application in clean production and processing standard chip-level requirements for dust higher than A-level, such a high standard to be applied in a number of major high grade chip production. 5μm and below the number of dust is strictly controlled within 1000 per cubic meter, which is the industry called 1K level.
