Description
Application
Tetramethylammonium hydroxide pentahydrate (TMAH pentahydrate) is mainly used in semiconductor manufacturing photolithography and chemical processing. It is also used as a strong base in laboratory synthesis.
Purpose
It serves primarily as a strong metal-ion-free alkaline reagent particularly for developing photoresists in semiconductor fabrication and for carrying out base-catalyzed reactions.
General Description
Tetramethylammonium hydroxide pentahydrate is the hydrated form of tetramethylammonium hydroxide (TMAH) typically supplied as a white crystalline solid. It is highly alkaline and soluble in water.
