Sharaxaada

Tetramethylammonium hydroxide(TMAH ama TMAOH) waa milix afargeesle ah oo ammonium ah oo leh caanaha molecular [(CH)₃)₄N]⁺[OH]^-, waana xubinta ugu fudud ee fasalka xeryahooda ammonium-ka quaternary.Mid ka mid ah adeegsigeeda warshadaha ayaa loogu talagalay etching anisotropic ee silikoon.Waxa kale oo loo isticmaalaa sida dareeraha aasaasiga ah ee horumarinta photoresisist acidic ee geeddi-socodka photolithography.Maadaama ay tahay kicinta wareejinta wejiga, aad bay waxtar ugu leedahay ka-qaadista sawir-qaadista.Waxa kale oo loo isticmaalaa sidii surfactant ah ee isku dhafka ferrofluid, si looga hortago agglomeration.

Odhaah*

Tetramethylammonium Hydroxide (2.380%, 20.0%, heerka elektarooniga ah), TMAH (25%, 98%, fasalka warshadaha) ayaa sidoo kale diyaar ah, fadlan nala soo xiriir wixii faahfaahin ah.

Codsiga

1) Dhinaca falanqaynta, tetramethylammonium Hydroxide waxaa loo isticmaali karaa sida reagent polarographic.

2) Marka la eego sifaynta alaabta, waxa loo isticmaalay sidii alkali dambaska ah si loo soo saaro qayb macdan ah.

3) warshadaha elektiroonigga ah, gaar ahaan sida horumariyaha iska caabbinta togan, silikoon wafer qoyan iyo xal aad u nadiif ah oo loogu talagalay geeddi-socodka CMP.

4) soo saarida wareegyada isku dhafan, bandhigyada crystal dareere, looxyada daabacan, capacitors, dareemayaal, iyo qaybo kale oo badan oo elektaroonik ah.
