Controlling Electrostatic Discharge (ESD) in Cleanrooms: A Comprehensive Guide
Maintaining a pristine cleanroom necessitates rigorous control of electrostatic discharge (ESD). ESD, caused from accumulation of static charge, can detrimentally damage sensitive devices used in semiconductor manufacturing. Appropriate ESD prevention methods require bonding each equipment, employing static-dissipative items like surfaces, attire, and instruments, and requiring atmospheric control to lessen charge accumulation. Further, personnel education on proper ESD procedures is absolutely essential for ensuring cleanroom integrity.
