Maintaining a pristine cleanroom necessitates careful control of electrostatic phenomena (ESD). ESD, stemming from generation of static potential, can severely damage sensitive components used in micro-device fabrication. Successful ESD reduction approaches include earthing all apparatus, utilizing ESD-safe substances like coverings, attire, and instruments, and enforcing humidity control to reduce charge accumulation. Additionally, personnel training on proper ESD techniques is necessarily vital for guaranteeing area quality.
