Tetramethylammonium hydroxide

Tetramethylammonium hydroxide is a quaternary ammonium salt. It is used as an anisotropic etchant of silicon. It is also used as a basic solvent in the development of acidic photoresist in the photolithography process. Since it is a phase transfer catalyst, it is highly effective in stripping photoresist. It is also used as a surfactant in the synthesis of ferrofluid, to prevent agglomeration.
