 Clean room clean room temperature and humidity control temperature and humidity are mainly determined according to process requirements, but under the conditions required to meet the process should take into account the person's sense of comfort. With the improvement of air cleanliness requirements, the process appears to require more stringent temperature and humidity are also trend. After specific process temperature requirements also cited, but as a general principle, due to increasingly sophisticated precision, so the scope of the requirements for temperature fluctuations smaller. For example, in the production of large scale integrated circuit lithography exposure process static distribution center decontamination, as the difference in thermal expansion coefficient of the glass mask material and the wafer have become increasingly smaller. 100 um diameter wafers, the temperature rise of 1 degree, it caused a 0.24um linear expansion, so there must be a constant temperature ± 0.1 degrees, while the requirements of generally low humidity values, because people sweat later, the product will have pollution, especially they are afraid of sodium semiconductor plant decontamination, this workshop temperature should not exceed 25 degrees, high humidity generated more questions. When the relative humidity exceeds 55%, the walls of the cooling water pipes, condensation, when it occurs in a precision device or circuit can cause a variety of accidents. Relative humidity at 50% rust. In addition, the water molecules in the air through the dust silicon surface chemical adhesion adsorbed on the surface is difficult to remove when the humidity is too high. The higher the relative humidity, the more difficult to remove the adherent medical decontamination, but when the relative humidity is below 30%, but also due to an electrostatic force so that the particles are easily adsorbed on the surface, while a large number of semiconductor devices prone to breakdown. For optimum humidity range of wafer production 35-45%. The first step in selecting high quality air purification equipment, is to choose a good brand. Select air purification equipment should try to prioritize international brands and has a history of professional brand products. International brands have in terms of technology and product quality absolute advantage sterile decontamination, and good after-sales service, product descriptions and features clearly described. Select international brands have influence, can not get cheated guarantee inferior products.
