Masana'antu/Matsayin lantarki TMAH 25% Tetramethylammonium Hydroxide cas 75-59-2
TMAH 25% Tetramethylammonium Hydroxide cas 75-59-2
Cikakkun bayanai game da samfurin:
Sunan Samfura: TMAH 25% ; Tetramethylammonium Hydroxide
Lambar CAS: 75-59-2
Tsarin kwayoyin halitta: C4H13NO
Bayyanar: ruwa mara launi
Asalinsa a matsayin lu'ulu'u mara launi (wanda ke ɗauke da ruwa uku/biyar na lu'ulu'u), mai sauƙin sha danshi, tare da wani ƙamshi na ammonia da kuma ƙarfi na asali; yana shan carbon dioxide a cikin iska, yana samar da carbonate, alkali na halitta, tare da ƙarfi na lalata. Samfurin yana da nau'ikan takamaiman bayanai guda biyu: maganin ruwa da maganin methanol.
Tetramethylammonium hydroxide (TMAH ko TMAOH) gishirin ammonium ne na quaternary tare da dabarar kwayoyin halitta [(CH3)4N]+[OH]-, kuma shine mafi sauƙin memba na ajin mahaɗan ammonium na quaternary. Ɗaya daga cikin amfanin da yake da shi a masana'antu shine don yin etching na anisotropic na silicon. Hakanan ana amfani da shi azaman mai narkewa na asali wajen haɓaka photoresist mai acidic a cikin tsarin photolithography. Tunda shine mai haɓaka canja wuri na lokaci, yana da tasiri sosai wajen cire photoresist. Hakanan ana amfani da shi azaman surfactant a cikin haɗa ferrofluid, don hana haɗuwa.
1) A fannin bincike, ana iya amfani da tetramethylammonium Hydroxide a matsayin maganin polagraphic.
2) Dangane da tsarkakewar samfura, an yi amfani da shi azaman alkaline mara toka don lalata wasu abubuwan ƙarfe.
3) a masana'antar lantarki, musamman a matsayin mai haɓaka resister mai kyau, silicon wafer wet etchant da kuma mafita mai tsabta don tsarin CMP.
4) wajen kera da'irori masu haɗawa, nunin lu'ulu'u na ruwa, allunan da'ira da aka buga, capacitors, firikwensin, da sauran kayan lantarki da yawa.
