A cleanroom or clean room is an engineered space that maintains a very low concentration of airborne particulates. It is well isolated, well controlled from contamination , and actively cleansed. Such rooms are commonly needed for scientific research and in industrial production for all nanoscale processes, such as semiconductor manufacturing.
The cleanroom software engineering process is a software development process intended to produce software with a certifiable level of reliability. The central principles are software development based on formal methods, incremental implementation under statistical quality control, and statistically sound testing.
ISO 14644-1 covers the classification of air cleanliness in cleanrooms and associated controlled environments. Classification in accordance with this standard is specified and accomplished exclusively in terms of concentration of airborne particulates. [6]
A cleanroom is an engineered space that maintains a very low concentration of airborne particulates. Cleanroom or clean room may also re also refer to: "The Clean Room", a TV series episode; Cleanroom suit, overall garment worn in a cleanroom; Cleanroom mat, mat with an adhesive surface that is placed at the entrances or exits
In the microelectronics industry, a semiconductor fabrication plant, also called a fab or a foundry, is a factory where integrated circuits (ICs) are manufactured. [1]The cleanroom is where all fabrication takes place and contains the machinery for integrated circuit production such as steppers and/or scanners for photolithography, etching, cleaning, and doping.
Air showers are typically placed between a gowning area and cleanroom; after workers don appropriate garb and personal protective equipment, they enter the shower so that the pressurized air nozzles remove any residual particles from coveralls. Once the program cycle is complete, users exit through a second door into the cleanroom.
Contamination control is the generic term for all activities aiming to control the existence, growth and proliferation of contamination in certain areas. Contamination control may refer to the atmosphere as well as to surfaces, to particulate matter as well as to microbes and to contamination prevention as well as to decontamination.
Filter ceiling grid of a cleanroom for microelectronic (semiconductor) manufacturing with filter fan units installed A fan filter unit ( FFU ) is a type of motorized air filtering equipment. It is used to supply purified air to cleanrooms , laboratories , medical facilities or microenvironments by removing harmful airborne particles from ...
