Product Description

TMAH 25% Tetramethylammonium Hydroxide cas 75-59-2

Ruzivo rwechigadzirwa:

Product Name: TMAH 25% ; Tetramethylammonium Hydroxide

Nhamba yeCAS: 75-59-2

Molecular Formula: C4H13NO

Kuonekwa: mvura isina ruvara

yaro yepakutanga sekristaro isina ruvara (ine matatu/shanu mvura yekristaro), nyore kutora unyoro, nehumwe hwema ammonia uye hwakasimba hwakasimba; kusveta carbon dioxide mumhepo, kugadzira carbonate, organic alkali, nekuora kwakasimba. Chigadzirwa chacho chine marudzi maviri ezvirevo: mvura mhinduro uye methanol mhinduro.

Features

Tetramethylammonium hydroxide (TMAH kana TMAOH) inonzi quaternary ammonium salt 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.

Application

1) Muchikamu chekuongorora, tetramethylammonium Hydroxide inogona kushandiswa se polarographic reagent.

2) Panyaya yekucheneswa kwechigadzirwa, yaishandiswa sedota remahara alkali kuita sediment chimwe chinhu chesimbi.

3) muindasitiri yemagetsi, kunyanya seyakanaka resister developer, silicon wafer wet etchant uye super yakachena mhinduro yeCMP maitiro.

4) mukugadzirwa kwemasekete akabatanidzwa, liquid crystal displays, akadhindwa edunhu mabhodhi, capacitors, sensors, uye zvimwe zvakawanda zvemagetsi zvikamu.
