Integrated circuit of dust may cause open circuit, short circuit, dust directly affect the yield of product.The semiconductor industry (fab) of high degree of air clean production environment, also the most demanding for the requirement of the air filter.
Sea salt particles in the air is the enemy of all electronic industry, but the sea salt particles of dust in the air is larger, the common filter can be filtered out.Some people say that the ideal location should be far away from the coast of the electronic industry, can be economically developed coastal region, fab systematically was built in the coastal region, just spent more money on the filter.
The semiconductor industry is not widely considered to be "smokeless industry", it also has the environmental problems.Often use the latest technology and materials, some of the chemicals in its safety has not yet been assessed before they have a lot of use, a bit not careful will cause serious chemical pollution, both the groundwater pollution, also has the air pollution, the valley will ever pay the amazing price.In order to insurance, some enterprises also use chemical filter in the exhaust system.
Craze in China is at a new fab construction, therefore, in the next few years the domestic needs of hundreds of millions of yuan efficient filter and chemical filter, if filter domestic businesses as usual only keen on plagiarism, suspicion, gu faffing around each, not on the technology of enterprising, don't talk to each other, fab this rare market will belong to outsiders.
