Chemical Liquids hauv Semiconductor Kev Lag Luam: Precision Cleaning thiab Etching Agents

Lub tuam txhab semiconductor yog ib qho ntawm cov khoom siv dav dav rau cov dej haus tshuaj. Ntau yam tshuaj purity siab purity ua si ib txoj hauj lwm tseem ceeb hauv precision cleansing thiab etching ntawm qee theem hauv cov txheej txheem tsim.

Ua ntej, kev siv hluav taws xob ntawm cov dej haus ntawm qee theem hauv cov txheej txheem ntxuav. Semiconductor ntau lawm entails rov qab ntxuav ntawm wafer pem teb kom tshem tawm ntau yam kab mob. Cov dej haus tshuaj muaj xws li cov dej ntshiab ntshiab ultrapure, sulfuric acid, thiab hydrogen peroxide tau siv dav hauv cov txheej txheem no. Cov dej qab zib tshuaj no muaj qhov sib txawv ntawm solubility thiab dispersibility, uas tuaj yeem ua tiav cov khoom tsis huv nrog rau cov khib nyiab thiab cov hlau ions ntawm wafer pem teb, ua kom huv si ntawm wafer pem teb ua tau raws li cov qauv xav tau.

Tom ntej no yog kev siv dej haus tshuaj ntawm qee theem hauv cov txheej txheem etching. Thaum cov khoom siv semiconductor ntau lawm suav nrog cov khoom siv hluav taws xob, nws tseem ceeb heev kom xaiv cov yeeb yaj kiab tawv nqaij ntawm lub wafer pem teb kom zoo li tus qauv nyiam. Ntau cov kua qaub thiab alkaline, cov kuab tshuaj ntuj, thiab cov dej haus sib txawv ua lub luag haujlwm tseem ceeb ntawm txoj haujlwm no. Lawv muaj peev xwm raws li nws yuav tsum tau thiab controllably tso tawm lub hom phiaj ntaub nrog tawm inflicting kev puas tsuaj rau ntau qhov chaw, ua kom paub tseeb tias cov etching cuam tshuam raws li qhov yuav tsum tau layout.

Tsis tas li ntawd, cov dej haus tshuaj lom neeg kuj tseem ua haujlwm tseem ceeb hauv txoj hauv kev tom ntej xws li wafer pem teb sprucing thiab slim movie deposition. Tam sim no lawv tsis xav ua kom txaus siab rau cov cim qhia xws li kev coj dawb huv thiab kev ua haujlwm, txawm li cas los xij yuav tsum tau ua qee yam haujlwm hauv ib puag ncig yooj yim ceeb kom tsis txhob kis kab mob ntawm cov txheej txheem ntau lawm.
