Yog tias 3-amino-5-mercapto-1,2 nqus tau, 4-triazole, thov txav tus neeg mob mus rau huab cua ntshiab; Thaum kis rau ntawm daim tawv nqaij, hle cov khaub ncaws paug thiab ntxuav daim tawv nqaij kom huv si nrog xum npum thiab dej. Yog koj tsis xis nyob, nrhiav tswv yim kho mob; yog tias koj muaj qhov muag pom meej, cais cov tawv muag, yaug nrog dej ntws los yog ua kua ntsev, thiab nrhiav tswv yim kho mob tam sim ntawd; yog tias noj, kwv yws sai li sai tau, tsis txhob ua rau ntuav, thiab nrhiav tswv yim kho mob tam sim ntawd.
Nws yog siv los npaj tov tshuaj ntxuav photoresist
Hauv cov txheej txheem cov LED thiab semiconductor kev tsim tawm, lub npog ntsej muag ntawm photoresist yog tsim nyob rau saum npoo ntawm qee cov ntaub ntawv, thiab cov qauv raug xa mus tom qab kis tas. Tom qab tau txais cov qauv uas yuav tsum tau ua, tus kws yees duab seem xav kom hle tawm ua ntej cov txheej txheem tom ntej. Nyob rau hauv txoj kev no, nws yuav tsum ua kom tiav qhov tsis tsim nyog photoresist yam tsis muaj qhov xeb rau txhua txheej. Tam sim no, photoresist kev daws teeb meem yog feem ntau ntawm cov ncov qaumteb qabteb organic solvent, muaj zog alkali thiab / lossis dej, thiab lwm yam. Cov.
Ib yam tshiab ntawm cov tshuaj ntxuav yeeb tshuaj (photoresist) tshuaj tu tau tsim, uas yog tshuaj ntxuav tes tsis zoo-muaj kua qis. Nws muaj: cawv amine, 3-amino-5-mercapto-1,2,4-triazole thiab cosolvent. Qhov kev yees duab zoo li tshuaj ntxuav tu no tuaj yeem siv los tshem tawm photoresist hauv LED thiab semiconductor. Nyob rau tib lub sijhawm, nws tsis muaj kev tawm tsam rau lub substrate, xws li hlau hlau. Dab tsi ntxiv, lub kaw lus muaj cov dej muaj zog tsis kam thiab dav nws lub qhov rais ua haujlwm. Nws muaj cov ntawv thov kev cia siab nyob rau hauv cov teb ntawm LED thiab semiconductor nti tu.
