TMAH

Tetramethyl ammonium hydroxide (TMAH): Toxicity, Hazards and Controls The Semiconductor Environmental, Safety and Health Association (SESHA) conducted a webinar about this chemical, commonly used as a “developer” in the semiconductor device manufacturing industry. There are a growing number of semiconductor processing applications which propose to use TMAH at high concentrations and sometimes at elevated temperatures. Tool vendors, chemical formulators, and other semiconductor companies may not be aware of TMAH’s high acute systemic toxicity. http://seshaonline.org Read more
