cleanroom
Dust-free manufacturing space
A cleanroom is a controlled environment where airborne particles, dust, and contaminants are kept to extremely low levels through filtered air, special surfaces, and strict protocols.
Workers typically wear protective garments—gowns, gloves, masks—to avoid introducing contamination.
Cleanrooms are essential in semiconductor manufacturing, pharmaceuticals, and aerospace: The microchips are assembled in a Class 100 cleanroom.
In software, cleanroom development refers to writing code without exposure to proprietary source material, avoiding copyright issues.
