Tetramethylammonium hydroxide(TMAH kana TMAOH) inonzi quaternary ammonium munyu ine molecular formula [(CH3)4N]+[OH]-, uye ndiyo nhengo yakapfava yekirasi yeorganic quaternary ammonium compounds.Imwe yekushandiswa kwayo kwemaindasitiri ndeye anisotropic etching yesilicon.Iyo inoshandiswawo seyakakosha solvent mukuvandudza acidic photoresist mune photolithography process.Sezvo iri chikamu chekufambisa catalyst, inoshanda zvakanyanya mukubvisa photoresist.Iyo inoshandiswawo seyakagadziriswa mukugadzirwa kweferrofluid, kudzivirira kusangana.
