Maintaining a pristine environment necessitates strict management of electrostatic events (ESD). ESD, resulting from accumulation of static electricity, can seriously harm sensitive parts used in semiconductor fabrication. Effective ESD reduction approaches involve bonding each machinery, employing ESD-safe substances like coverings, clothing, and instruments, and enforcing moisture management to reduce charge build-up. Further, personnel education on proper ESD techniques is completely essential for ensuring cleanroom purity.
