a contamination-controlled environment and is essential in the industrial manufacture of many electronic, semiconductor, optical, pharmaceutical and medical products
a controlled environment for building and testing a satellite
a controlled environment where products are manufactured
a defined area of space in which the air must be so pure that even invisible particles (twenty times smaller than the eye can see) are filtered out
a facility in which air content is strictly controlled
a laboratory-like setting featuring ultra-high filtration of particles and control of interior climate and static to meet the requirements for handling highly sensitive silicon wafers
a manufacturing environment that has a low
an enclosed (isolated) work area which incorporates high standards of control -- humidity, temperature and filtration to minimize all forms of particulate matter and contamination
an environment in which the concentration of airborne particles are controlled to specific limits
an environment where airborn particulates are controlled through an exchange of highly filtered
enclosed ultra-clean space necessary for semiconductor manufacturing. Airborne particles are removed from the space to specified minimum levels, room temperature and humidity are strictly controlled; clean rooms are rated and range from Class 1 to Class 10,000. The number corresponds to the number of particles per cubic foot. learn more.
The Nanolab is a class 1000 cleanroom, which means there are less than 1000 particles of 1 m or more, per cubic foot.
Room or facility in which the concentration of airborne particles is controlled to specified limits defined by Federal Standard 209 or ISO 14644
A room (facility) in which the air supply, air distribution, filtration of air supply, materials of construction, and operating procedures are regulated to control airborne particle concentrations to meet appropriate cleanliness levels.
A room designed, maintained, and controlled to prevent particle and microbiological contamination of drug products. Such a room is assigned and reproducibly meets an appropriate air cleanliness classification.
An area which incorporates high standards of control for humidity, temperature and air pressure and all forms of particulate matter and contamination. Go to top
Room containing extremely low numbers of dust particles used for the manufacture of semiconductors and other nanoscale electrical items.
A confined area in which the humidity, temperature, particle matter, and contamination are precisely controlled within specified parameters.
A confined area in which the humidity, temperature, dust particles and contamination are precisely controlled. The air in these rooms is thousands of times cleaner than that in a typical hospital operating room. The "class" of the cleanroom is defined by the maximum number of particles in one cubic foot of cleanroom space. ( see class 100 cleanroom)
The super clean environment in which semiconductors are manufactured. The lower the rating, the cleaner the facility. These rooms typically have hundreds of thousands of particles less per cubic foot than the normal environment.
The portion of a fab where semiconductors are manufactured. These rooms are strictly monitored to ensure successful manufacturing of semiconductors.
a room combining the use of air filters and continuous air circulation to produce levels of air borne particles that are lower, and typically much lower than normal atmospheric dust levels. Outdoor atmospheric dust levels are on the order of 400,000 particles/ft3 0.5µm in size. Cleanroom cleanliness levels generally are agreed to begin at 100,000 particles/ft3 and extend down to 0.01 particles/ft3 or less! See also, Cleanroom Class.
An entire room in which the number and size of ambient particles is minimized and controlled. Clean rooms are classified by the average number of particles present greater than 0.5 microns. For example, Class 10 clean rooms have no more than 10 particles greater than 0.5 microns per cubic foot of air; Class 100 clean rooms have no more than 100 particles greater than 0.5 microns per cubic foot of air; Class 1,000 clean rooms have no more than 1,000 particles greater than 0.5 microns per cubic foot of air; and so on. Class I 0 corresponds to Grade 1.5 of Federal Standard 209E, Class 100 corresponds to Grade 2.5, Class 1000 corresponds to Grade 3.5, etc. Enacted in 1992, Federal Standard 209E establishes both metric and English standard classes of air cleanliness for airborne particulate levels in clean rooms and clean zones. This standard prescribes methods for class verification and monitoring of air cleanliness and addresses other factors as they affect control of airborne particulate contamination. There are five class limits with specific particulate sizing per volume units.
A cleanroom is an environment, typically used in manufacturing or scientific research, that has a low level of environmental pollutants such as dust, airborne microbes, aerosol particles and chemical vapors. More accurately, a cleanroom has a controlled level of contamination that is specified by the number of particles per cubic meter at a specified particle size. To give a perspective, the ambient air outside in a typical urban environment might contain as many as 35,000,000 particles per cubic meter, 0.5 µm and larger in diameter, corresponding to an ISO class 9 cleanroom.
