Why must aemiconductore chips be made in clean rooms?

Semiconductor chips must be made in clean rooms to prevent contamination from dust, particles, and airborne impurities, which can significantly affect their performance and reliability. Even minute contaminants can lead to defects in the microfabrication process, resulting in malfunctioning chips. Clean rooms maintain strict environmental controls, including temperature, humidity, and air quality, ensuring optimal conditions for the delicate manufacturing processes involved in chip production. This controlled environment is essential for achieving the precision required in modern semiconductor technology.
