MDC Gas Delivery Products is proud to announce a brand new class 100 clean room at the Hayward facility.
This expansion is part of our ongoing efforts to provide our customers with the most advanced and dependable vacuum technology available. Using these new resources, our talented technicians and welders will now have greater capability to meet demand and exceed expectations in the semiconductor industry and other quickly evolving fields.
Clean rooms are controlled, isolated environments designed to limit the level of airborne particles and contaminants. The surrounding air outside in a typical urban area contains around 35,000,000 particles per cubic meter sized 0.5 micrometers or larger. By comparison, our new class 100 clean room contains around 3,500 particles per cubic meter – around 10,000% less contamination than outside.
One of the secrets to a clean room’s cleanliness is in the air. Air entering the clean room goes through a filtration process, and air inside the cleanroom is constantly recirculated through high-efficiency particulate air (HEPA) and/or ultra-low particulate air (ULPA) filters to remove internally generated contaminants.
Staff enter and leave the clean room through an airlock and wear protective clothing such as hoods, face masks, gloves, boots, and coveralls. Equipment inside the cleanroom is designed to generate minimal air contamination. Only special mops and buckets are used. Cleanroom furniture is designed to produce a minimum of particles and is easy to clean.
Clean rooms are classified according to the number and size of particles permitted per volume of air. Large numbers like “class 100” or “class 1000” refer to FED-STD-209E, and denote the number of particles of size 0.5 µm or larger permitted per cubic foot of air. Small numbers refer to ISO 14644-1 standards, which specify the decimal logarithm of the number of particles 0.1 µm or larger permitted per m3 of air. So, for example, an ISO class 5 cleanroom has at most 105 particles/m3.
Clean rooms are used in practically every industry where small particles can adversely affect the manufacturing process. This includes applications in aeronautics, optics, biotechnology, nanotechnology, pharmaceuticals, medical technology, military research, telecommunications.
Clean rooms are especially important to the development and manufacture of semiconductors.
