Next Generation TMAH Alternatives

SACHEM’s bulk silicon etch platform offers a range of alternatives to tetramethylammonium hydroxide including Envure SE™ and SiAN Etch™.  These products are tunable with temperature and concentration for integrated circuit (IC) and photovoltaic (PV) applications.  Next generation TMAH alternatives have higher LD50 levels than TMAH in dermal exposures. SACHEM can supply these alternatives in high purity grades.



We take pride in our safety record to protect our sites, associates and communities. SACHEM has safely manufactured and handled concentrated TMAH since the 1970’s and our global plant sites have received many environment and safety awards.
