MDC Gas Delivery Products takes pride in introducing the latest class 100 cleanroom at its Hayward facility.
This expansion is part of the company’s progressive efforts to offer its customers with the most reliable and sophisticated vacuum technology at hand. These new resources will now offer MDC’s highly skilled welders and technicians a greater potential to fulfill the demands and exceed expectations in not only the semiconductor industry but also other rapidly evolving fields.
What are Cleanrooms?
Cleanrooms are isolated, controlled environments intended to restrict the level of contaminants and airborne particulates. In a typical urban area, one cubic meter of the ambient outside air contains about 35,000,000 particles sized 0.5 μm or larger. In contrast, MDC’s new class 100 cleanroom contains only about 3500 particles per cubic meter — nearly 10,000% less contamination compared to outside.
The secret to the cleanliness of a cleanroom is in the air. The air that enters the cleanroom undergoes a filtration process, and the air within the cleanroom is continuously recirculated using ultra-low particulate air (ULPA) or high-efficiency particulate air (HEPA) filters in order to eliminate contaminants that are produced internally.
Staff who enter and leave the cleanroom wear protective clothing such as face masks, hoods, boots, gloves, and coveralls and go through an airlock. The equipment used inside the cleanroom is designed to produce a limited amount of contaminants. Only special buckets and mops are used. The furniture used in a cleanroom is easy to clean and designed to generate minimal particles.
Cleanrooms are classified based on the size and number of particles allowed per volume of air. Large numbers such as “class 100” or “class 1000” refer to FED-STD-209E, and specify the number of particles sized 0.5 µm or larger allowed per cubic foot of air. Small numbers pertain to ISO 14644-1 standards, stipulating the decimal logarithm of the number of particles sized 0.1 µm or larger allowed per cubic meter of air. Therefore, for instance, an ISO class 5 cleanroom has a maximum of 105 particles per cubic meter.
Cleanrooms are employed in almost every industry where the manufacturing process could be drastically affected by the presence of small particulates. This finds applications in nanotechnology, aeronautics, pharmaceuticals, optics, medical technology, biotechnology, telecommunications and military research.
Cleanrooms are specifically vital to the development and production of semiconductors.
The ultra-high purity gas delivery products from MDC are welded and assembled in a class 100 cleanroom by some of the most experienced and highly skilled welders and technicians in the industry. Several members of the MDC Gas Delivery Products division team have been with the company for more than 10 years and reflect the commitment of the company to constantly offer competitively priced and high-quality components to its customers.
