Kev siv cov txheej txheem ntub dej los tsim cov khoom siv hluav taws xob me me hu ua semiconductors. Cov khoom siv semiconductors yog cov khoom tseem ceeb hauv cov khoom siv xws li khoos phis tawj thiab xov tooj ntse. Kev siv cov txheej txheem ntub dej pab tsim cov khoom me me ntawd los ntawm kev xaiv cov khoom ntawm ib txheej tawm ntawm qhov chaw. Yog li, cia peb nrhiav seb: peb tab tom yuav ua ib pawg ntawm cov semiconductors siv Semixlab. kev txiav ntub dej.
Kev siv cov txheej txheem etching ntub dej siv tau los txiav cov qauv meej rau ntawm cov ntaub ntawv xws li silicon. Thaum nws los txog rau kev ua cov semiconductors, kev siv cov txheej txheem etching ntub dej yog qhov tseem ceeb rau kev tsim cov voj voog me me uas ua rau cov khoom siv digital khiav. Cov kws ua haujlwm tuaj yeem txiav cov khoom tshwj xeeb los ua cov duab thiab cov qauv los ntawm kev siv cov kua dej ntawm qhov chaw ntawm cov khoom siv.
Cov txheej txheem etching ntub muaj ntau kauj ruam. Ua ntej, cov khoom siv yog coated hauv ib txheej tiv thaiv uas hu ua lub ntsej muag. Lub ntsej muag no muaj kev tiv thaiv siab rau cov kua etching thiab muaj txiaj ntsig zoo hauv kev ua qauv throughput. Tom qab ntawd, cov khoom siv raug dipped rau hauv qhov nruab nrab etching, uas yaj cov cheeb tsam tsis muaj kev tiv thaiv mus rau ib qho qauv xav tau. Wet etching yog li cas cov yam ntxwv me me xws li transistors thiab capacitors tau ua rau ntawm semiconductor wafers.

Semixlab al2o3 etching ntub dej vam khom cov tshuaj lom neeg tshwm sim ntawm cov kua etching thiab cov khoom siv. Cov khoom siv sib txawv xav tau cov kua etching sib txawv kom tsim tau cov txiaj ntsig xav tau. Ib txoj kev piv txwv rau kev tsim cov qauv silicon yog los ntawm etching, siv cov kua hydrofluoric acid, uas teb nrog silicon los tsim cov qauv. Cov kws ua haujlwm tuaj yeem tau txais cov txiaj ntsig ntxaws los ntawm kev tswj lub zog thiab qhov kub ntawm cov kua etching.

Kev siv cov txheej txheem etching ntub muaj qee qhov zoo. Nws yog ib txoj kev pheej yig thiab yooj yim siv los tsim cov qauv zoo ntawm qhov chaw du. Kev siv cov txheej txheem etching ntub kuj siv rau ntau yam khoom thiab siv dav hauv kev tsim cov khoom siv semiconductor. Tab sis, zoo li lwm yam, nws muaj nws qhov tsis zoo. Nws kuj tseem tuaj yeem qeeb, thiab nyuaj rau tiv thaiv cov txheej txheem etching tob dua thiab loj dua. Raws li thev naus laus zis nce qib, lwm cov txheej txheem, xws li kev etching qhuav, tab tom tsim los daws cov teeb meem no.

Muaj ob peb lub tswv yim pab tau rau cov engineers kom ntub etch kom zoo. Ua ntej, kev tsim lub npog ntsej muag yog qhov tseem ceeb los tiv thaiv cov khoom siv hauv etching. Lub npog ntsej muag zoo yuav ua kom ntseeg tau tias tsuas yog cov cheeb tsam raug ntawm qhov chaw raug etched, lav cov qauv meej. Tom qab ntawd dua muaj qhov kub thiab lub zog ntawm cov kua etching uas tswj hwm kuj yuav tsum tau ua. Qhov kawg tab sis tsis tsawg kawg nkaus, cov txheej txheem kuaj mob zoo, xws li kev siv cov ntaub ntawv huv si, yuav tiv thaiv teeb meem thiab pab koj ua tiav Semixlab kom zoo. Etching Focus nplhaib.
