Qib Industrial/Electronic TMAH 25% Tetramethylammonium Hydroxide CAS 75-59-2
TMAH 25% Tetramethylammonium Hydroxide CAS 75-59-2
Product details:
Khoom npe: TMAH 25% ; Tetramethylammonium Hydroxide
CAS Nr .: 75-59-2
Cov mis mos molecular: C4H13NO
Cov tsos mob: tsis muaj xim tsis muaj kua
nws cov khoom qub yog cov xim tsis muaj xim (muaj peb/tsib siv lead ua dej), yooj yim nqus dej noo, muaj qee yam ammonia tsw thiab muaj zog hauv paus; absorbing carbon dioxide nyob rau hauv huab cua, tsim carbonate, organic alkali, muaj zog corrosivity. Cov khoom muaj ob hom kev qhia tshwj xeeb: dej tov thiab tshuaj methanol.
Tetramethylammonium hydroxide (TMAH lossis TMAOH) yog quaternary ammonium ntsev nrog cov mis molecular [(CH3)4N] + [OH]-, thiab yog cov tswv cuab yooj yim tshaj plaws hauv chav kawm ntawm cov organic quaternary ammonium compounds. Ib qho ntawm nws cov kev lag luam siv yog rau anisotropic etching ntawm silicon. Nws kuj yog siv los ua ib qho hnyav hnyav hauv kev txhim kho acidic photoresist hauv cov txheej txheem photolithography. Txij li thaum nws yog ib theem hloov catalyst, nws muaj txiaj ntsig zoo hauv stripping photoresist. Nws kuj yog siv los ua ib qho surfactant nyob rau hauv cov synthesis ntawm ferrofluid, los tiv thaiv agglomeration.
1) Hauv kev tsom xam, tetramethylammonium Hydroxide tuaj yeem siv ua polarographic reagent.
2) Nyob rau hauv cov nqe lus ntawm cov khoom purification, nws tau siv raws li tshauv dawb alkali rau sediment ib co metallic keeb.
3) hauv kev lag luam hluav taws xob, tshwj xeeb tshaj yog cov neeg tsim khoom zoo, silicon wafer ntub etchant thiab super huv tov rau CMP txheej txheem.
4) nyob rau hauv kev tsim khoom ntawm kev sib xyaw ua ke, cov kua siv lead ua kua, cov ntawv luam tawm Circuit Court boards, capacitors, sensors, thiab ntau lwm yam khoom siv hluav taws xob.
