TMAH 25% Tetramethylammonium Hydroxide cas 75-59-2
Lintlha tsa sehlahisoa:
Lebitso la Sehlahisoa: TMAH 25% ; Tetramethylammonium Hydroxide
Nomoro ea CAS: 75-59-2
Foromo ea molek'hule: C4H13NO
Ponahalo: metsi a senang mmala
ea eona ea pele e le kristale e se nang 'mala (e nang le metsi a kristale a mararo / a mahlano), ho bonolo ho monya mongobo, ka monko o itseng oa ammonia le motheo o matla; ho monya carbon dioxide moeeng, ho etsa carbonate, organic alkali, ka ho bola ho matla. Sehlahisoa se na le mefuta e 'meli ea litlhaloso: tharollo ea metsi le tharollo ea methanol.
Tetramethylammonium hydroxide (TMAH kapa TMAOH) ke letsoai la quaternary ammonium le nang le foromo ea molek'hule [(CH3)4N]+[OH]-,' me ke setho se bonolo ka ho fetisisa sa sehlopha sa metsoako ea quaternary ammonium. E 'ngoe ea ts'ebeliso ea eona ea indasteri ke ea anisotropic etching ea silicon. E boetse e sebelisoa e le motsoako oa motheo ho nts'etsopele ea acidic photoresist ts'ebetsong ea photolithography. Kaha ke mokhoa oa ho fetisa phasewete, e sebetsa haholo ho hlobolisa photoresist. E boetse e sebelisoa e le surfactant ka synthesis ea ferrofluid, ho thibela agglomeration.
1) Karolong ea tlhahlobo, tetramethylammonium Hydroxide e ka sebelisoa e le reagent ea polarographic.
2) Mabapi le tlhoekiso ea sehlahisoa, e ne e sebelisoa e le molora o sa lefelloeng oa alkali ho senya ntho e itseng ea tšepe.
3) indastering ea elektronike, haholo-holo e le moqapi o motle oa ho hanyetsa, silicon wafer wet etchant le tharollo e hloekileng haholo bakeng sa ts'ebetso ea CMP.
4) ha ho etsoa lipotoloho tse kopaneng, lipontšo tsa kristale ea metsi, liboto tsa potoloho tse hatisitsoeng, li-capacitor, li-sensor le likarolo tse ling tse ngata tsa elektroniki.
