TMAH 25% Tetramethylammonium Hydroxide cas 75-59-2
Faahfaahinta alaabta:
Magaca Badeecada: TMAH 25% ; Tetramethylammonium Hydroxide
Lambarka CAS: 75-59-2
Qaacidda Molekuleeri: C4H13NO
Muuqaal: dareere aan midab lahayn
Asal ahaan waa kiristaal aan midab lahayn (oo ka kooban saddex/shan biyo kiristaal ah), si fudud loo nuugi karo qoyaanka, oo leh ur ammonia ah iyo aasaas adag; nuugaya kaarboon laba ogsaydh hawada, samaynaya kaarboon, alkali dabiici ah, oo leh daxal xooggan. Badeecaddu waxay leedahay laba nooc oo qeexitaanno ah: xalka biyaha iyo xalka methanol.
Tetramethylammonium hydroxide (TMAH ama TMAOH) waa cusbo ammonium ah oo quaternary ah oo leh qaacidada molecular [(CH3)4N]+[OH]-, waana xubinta ugu fudud ee fasalka isku-dhafka ammonium-ka dabiiciga ah ee quaternary. Mid ka mid ah isticmaalkeeda warshadaha waa qallajinta anisotropic ee silicon. Waxaa sidoo kale loo isticmaalaa sidii dareere aasaasi ah oo lagu horumarinayo sawir-qaadista aashitada ee habka sawir-qaadista. Maadaama ay tahay kiciyaha wareejinta marxaladda, waxay aad waxtar ugu leedahay ka saarista sawir-qaadista. Waxaa sidoo kale loo isticmaalaa sidii surfactant marka la samaynayo ferrofluid, si looga hortago isku-darka.
1) Dhinaca falanqaynta, tetramethylammonium Hydroxide waxaa loo isticmaali karaa sidii fal-celin polagraphic ah.
2) Marka laga hadlayo nadiifinta badeecada, waxaa loo isticmaalay sidii alkali aan dambas lahayn si loo fadhiisiyo walxo bir ah.
3) warshadaha elektaroonigga ah, gaar ahaan horumariyaha iska caabbinta wanaagsan, silicon wafer qoyan oo silikoon ah iyo xal aad u nadiif ah oo loogu talagalay habka CMP.
4) soo saarista wareegyada isku dhafan, bandhigyada kiristaalka dareeraha ah, looxyada wareegga daabacan, kapacitors-ka, dareemayaasha, iyo qaybo kale oo badan oo elektaroonik ah.
