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.
The aim of cleanroom suitability tests is to determine the suitability of machines and operating utilities (air conditioning, venting, etc.) for use in cleanrooms. The tests must be carried out using measurement techniques as particle emission behavior cannot be adequately assessed by the naked eye or similar means.
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
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.
A cleanroom suit, clean room suit, or bunny suit, [1] [2] is an overall garment worn in a cleanroom, an environment with a controlled level of contamination. One common type is an all-in-one coverall worn by semiconductor and nanotechnology line production workers, technicians, and process / equipment engineers.
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]
Although the clean-room approach had been used as preventative measure in view of possible litigation before (e.g. in the Phoenix BIOS case), the NEC v. Intel case was the first time that the clean-room argument was accepted in a US court trial. A related aspect worth mentioning here is that NEC did have a license for Intel's patents governing ...
