Semiconductor research facilities present unique industrial hygiene challenges due to the extensive use of toxic, corrosive, flammable, and pyrophoric chemicals in highly controlled cleanroom environments. This presentation provides an applied overview of essential industrial hygiene principles for Environmental, Health, and Safety (EHS) professionals working with semiconductor research laboratories.

Key topics include basic toxicology for commonly used materials—such as hydrofluoric acid (HF), tetramethylammonium hydroxide (TMAH), hydrides (arsine, phosphine, diborane, germane, hydrogen selenide, and ammonia), chlorine, mineral acids, and organic solvents. The webinar also examines engineering controls fundamental to semiconductor operations, including exhaust ventilation strategies and hazardous gas monitoring systems. Discussion extends to the use of direct-reading instruments for both emergency response and exposure screening, aligned with American Industrial Hygiene Association (AIHA) professional competencies.

Finally, the presentation links major cleanroom processes—such as ion implantation, chemical and physical vapor deposition, molecular beam epitaxy, and wet and dry etching—with their predominant chemical hazards and corresponding control strategies. Participants will gain practical insights into integrating industrial hygiene principles into semiconductor process design, hazard anticipation, and operational safety management.
