Ingcaciso yeMveliso

I-TMAH 25% Tetramethylammonium Hydroxide cas 75-59-2

Iinkcukacha zemveliso:

Igama leMveliso: TMAH 25%; Tetramethylammonium Hydroxide

Inombolo ye-CAS: 75-59-2

Ifomula yeMolekyuli: C4H13NO

Inkangeleko: ulwelo olungenambala

Yantlandlolo njengekristale engenambala (equlethe amanzi amathathu/amahlanu ekristale), kulula ukufunxa umswakama, inevumba elithile le-ammonia kunye nesiseko esinamandla; ifunxa ikharbon diokside emoyeni, yenza i-carbonate, i-organic alkali, kunye nokubola okunamandla. Le mveliso ineentlobo ezimbini zeenkcukacha: isisombululo samanzi kunye nesisombululo se-methanol.

Iimbonakalo

I-Tetramethylammonium hydroxide (TMAH okanye i-TMAOH) yityuwa ye-quaternary ammonium enefomula yemolekyuli [(CH3)4N]+[OH]-, kwaye yeyona ilula kwiklasi yeekhompawundi ze-organic quaternary ammonium. Enye yeendlela ezisetyenziswa ngayo kwimizi-mveliso kukusika i-silicon nge-anisotropic. Ikwasetyenziswa njengesinyibilikisi esisisiseko ekuphuhlisweni kwe-acidic photoresist kwinkqubo ye-photolithography. Ekubeni iyi-phase transfer catalyst, isebenza kakhulu ekususeni i-photoresist. Ikwasetyenziswa njenge-surfactant ekuhlanganiseni i-ferrofluid, ukuthintela ukuhlangana.

Isicelo

1) Kwicala lohlalutyo, i-tetramethylammonium Hydroxide ingasetyenziswa njenge-reagent ye-polarographic.

2) Ngokuphathelele ukucocwa kwemveliso, yayisetyenziswa njenge-alkali engenalo uthuthu ukuze ichithe into ethile yesinyithi.

3) kwishishini le-elektroniki, ingakumbi njengomphuhlisi we-resister olungileyo, i-silicon wafer etchant emanzi kunye nesisombululo esicocekileyo kakhulu senkqubo ye-CMP.

4) ekwenzeni iisekethe ezidityanisiweyo, izibonisi zekristale yolwelo, iibhodi zesekethe eziprintiweyo, ii-capacitors, ii-sensors, kunye nezinye izinto ezininzi ze-elektroniki.
