Papa ʻoihana/uila TMAH 25% Tetramethylammonium Hydroxide cas 75-59-2
ʻO TMAH 25% Tetramethylammonium Hydroxide cas 75-59-2
Nā kikoʻī huahana:
Inoa Huahana: TMAH 25%; Tetramethylammonium Hydroxide
Helu CAS: 75-59-2
Formula Molekala: C4H13NO
ʻAno: wai kala ʻole
ʻO kona kumu mua he kristal kala ʻole (loaʻa nā wai kristal ʻekolu/ʻelima), maʻalahi ke omo i ka makū, me kekahi ʻala ammonia a me ka basicity ikaika; omo i ke kalapona ʻokikene i ka lewa, hana i ka carbonate, alkali organik, me ka corrosivity ikaika. Loaʻa i ka huahana ʻelua ʻano kikoʻī: ka hopena wai a me ka hopena methanol.
ʻO Tetramethylammonium hydroxide (TMAH a i ʻole TMAOH) he paʻakai ammonium quaternary me ke ʻano molekala [(CH3)4N]+[OH]-, a ʻo ia ka lālā maʻalahi loa o ka papa o nā hui ammonium quaternary organik. ʻO kekahi o kāna hoʻohana ʻoihana no ka etching anisotropic o ka silicon. Hoʻohana ʻia hoʻi ia ma ke ʻano he solvent kumu i ka hoʻomohala ʻana o ka photoresist acidic i ke kaʻina hana photolithography. ʻOiai he mea hoʻouluulu hoʻoili pae, he mea kūpono loa ia i ka wehe ʻana i ka photoresist. Hoʻohana ʻia hoʻi ia ma ke ʻano he surfactant i ka synthesis o ferrofluid, e pale aku i ka agglomeration.
1) Ma ke ʻano o ka nānā ʻana, hiki ke hoʻohana ʻia ka tetramethylammonium Hydroxide ma ke ʻano he reagent polarographic.
2) I ke ʻano o ka hoʻomaʻemaʻe ʻana o ka huahana, ua hoʻohana ʻia ia ma ke ʻano he alkali ʻaʻohe lehu e hoʻoheheʻe i kekahi mea metala.
3) ma ka ʻoihana uila, ʻoiai ma ke ʻano he mea hoʻomohala resister maikaʻi, silicon wafer wet etchant a me ka hopena maʻemaʻe loa no ke kaʻina hana CMP.
4) i ka hana ʻana o nā kaapuni i hoʻohui ʻia, nā hōʻikeʻike kristal wai, nā papa kaapuni i paʻi ʻia, nā capacitors, nā sensor, a me nā ʻāpana uila ʻē aʻe he nui.
