Ammonium Hydrogen Difluoride (CAS: 1341 – 49 – 7) tau yog ib qho kev saib xyuas ntau ntxiv. Nws ua lub luag haujlwm tseem ceeb hauv ntau lub koom haum, tsav tsheb tsim kho tshiab thiab cov txheej txheem tsim khoom.

Ammonium Hydrogen Difluoride siv dav hauv kev lag luam semiconductor. Ua tus neeg sawv cev etching, nws ua rau muaj kev hloov kho kom raug ntawm cov semiconductor wafers, uas yog qhov tseem ceeb rau kev tsim cov microchips siab heev. Nrog rau kev ua kom me me ntawm cov khoom siv hluav taws xob, qhov kev thov rau cov txheej txheem etching raug heev tau loj hlob, thiab Ammonium Hydrogen Difluoride tau ua pov thawj tias yog ib qho cuab yeej tseem ceeb hauv kev ua kom tau raws li cov kev xav tau no.

Kev lag luam iav kuj tseem siv cov tshuaj no ntau heev. Nws siv rau kev txiav iav, ua rau muaj kev tsim cov qauv zoo nkauj ntawm cov iav. Tsis tas li ntawd, nws koom nrog kev kho cov ntawv silicon - hlau, txhim kho lawv cov khoom thiab ua rau lawv haum rau ntau yam kev siv hauv kev lag luam hluav taws xob thiab tsheb.

Tab sis zoo li ntau yam tshuaj lom neeg hauv kev lag luam, Ammonium Hydrogen Difluoride muaj qee yam kev xav txog kev nyab xeeb. Vim nws qhov xwm txheej corrosive, kev tuav thiab khaws cia kom zoo yog qhov tseem ceeb. Nyob rau hauv lub hlis tas los no, muaj kev hu kom muaj kev cai lij choj kev nyab xeeb nruj dua hauv kev thauj mus los thiab siv cov tshuaj no kom txo qhov kev pheej hmoo ntawm kev sib tsoo.

Txawm hais tias muaj teeb meem los xij, kev tshawb nrhiav txog kev siv Ammonium Hydrogen Difluoride kom zoo dua thiab muaj kev nyab xeeb dua tseem tab tom ua mus. Cov kws tshawb fawb tab tom tshawb nrhiav cov qauv tshiab thiab cov txheej txheem siv los ua kom nws ua haujlwm tau zoo dua thaum txo cov kev phom sij.

Thaum cov lag luam txuas ntxiv hloov zuj zus, Ammonium Hydrogen Difluoride yuav tseem muaj txiaj ntsig. Yog tias muaj kev ntsuas kev nyab xeeb zoo thiab kev tsim kho tshiab tas mus li, nws yuav txuas ntxiv txhawb nqa kev loj hlob ntawm kev tsim khoom siv thev naus laus zis siab thiab lwm yam kev lag luam tseem ceeb.
