Maintaining a pristine cleanroom necessitates rigorous control of electrostatic events (ESD). ESD, caused from build-up of static electricity, can severely affect sensitive parts used in semiconductor manufacturing. Effective ESD reduction methods require earthing all apparatus, utilizing static-dissipative substances like flooring, clothing, and tooling, and requiring atmospheric regulation to lessen voltage accumulation. Further, personnel training on proper ESD procedures is necessarily vital for maintaining environment quality.
