Maintaining a pristine environment necessitates strict management of electrostatic discharge (ESD). ESD, resulting from build-up of static charge, can detrimentally affect sensitive components used in micro-device fabrication. Effective ESD reduction strategies require grounding every apparatus, using ESD-safe items like flooring, garments, and fixtures, and implementing humidity regulation to reduce charge generation. Further, personnel education on proper ESD techniques is absolutely essential for ensuring cleanroom quality.
