Controlling Electrostatic Discharge (ESD) in Cleanrooms: A Comprehensive Guide
Maintaining a pristine environment necessitates careful regulation of electrostatic events (ESD). ESD, stemming from build-up of static electricity, can detrimentally damage sensitive parts used in semiconductor manufacturing. Effective ESD mitigation methods require earthing all equipment, using static-dissipative materials like coverings, attire, and tooling, and enforcing atmospheric regulation to reduce potential accumulation. Moreover, personnel instruction on proper ESD techniques is necessarily critical for maintaining area quality.
