Hauv kev lag luam semiconductor, qhov twg ib lub micron tuaj yeem yog qhov sib txawv ntawm cov khoom muaj txiaj ntsig zoo thiab qhov ua tsis tiav kim, kev xaiv cov khoom siv metrology yog qhov tseem ceeb heev. Raws li lithography thiab wafer kev tshuaj xyuas thawb cov ciam teb ntawm physics, cov hlau ib txwm muaj thiab txawm tias cov granite zoo tshaj plaws tab tom ncav cuag lawv cov kev txwv.
Alumina Ceramic (Al2O3) tau tshwm sim los ua qhov kev daws teeb meem zoo tshaj plaws rau cov chaw tsim khoom siv semiconductor. Nrog rau lub sijhawm khaws cia qhov tseeb uas tuaj yeem dhau cov ntaub ntawv ib txwm muaj ntau dua 10 xyoo, ceramics tsis yog khoom kim heev lawm - lawv yog qhov tsim nyog rau kev tsim kho.
Vim li cas Alumina Ceramic rau Semiconductors?
Ua ntej yuav tham txog cov ntawv thov, nws yog ib qho tseem ceeb kom nkag siab txog cov ntaub ntawv "triple-threat" profile:
-
Kev Ruaj Ntseg Thermal: Tus coefficient qis ntawm kev nthuav dav thermal (≈7 × 10^{-6}/K) ua kom cov kev ntsuas tseem sib xws txawm tias muaj cua sov los ntawm cov khoom siv ceev ceev.
-
Tsis-Nqus Hlau & Tsis-Conductive: Qhov tseem ceeb rau cov chaw nqus tsev thiab cov duab hluav taws xob-beam lithography uas muaj kev cuam tshuam magnetic tuaj yeem cuam tshuam cov kab teeb.
-
Xoom Corrosion: Tsis zoo li hlau, ceramics yog inert tshuaj lom neeg, ua rau lawv sib xws nrog cov txheej txheem ntxuav chav huv thiab cov chaw muaj roj corrosive.
5 Cov Ntawv Thov Tseem Ceeb hauv Cov Khoom Siv Semiconductor
1. Cov Theem Tshuab Lithography
Cov duab thaij duab niaj hnub no xav tau qhov chaw nanometer. Cov plaub fab ceramic thiab cov khoom siv ua lub luag haujlwm tseem ceeb rau theem wafer. Lawv qhov sib piv siab ntawm qhov hnyav thiab qhov tawv ua rau muaj kev nrawm nrawm yam tsis muaj kev co lossis "nrov" cuam tshuam nrog cov khoom hnyav dua.
2. Kev Tshuaj Xyuas Wafer & Kev Ntsuas
Hauv cov txheej txheem wafer geometry, Ceramic Master Squares yog siv los kho qhov perpendicularity thiab straightness ntawm cov scanning axes. Vim tias ceramic khaws nws cov duab tau ntau tshaj kaum xyoo, cov tshuab no xav tau tsawg dua qhov kev hloov kho dua tshiab, ua kom lub sijhawm ua haujlwm ntau tshaj plaws rau lub fab.
3. Kev Sib Dhos Ua Ntej ntawm Cov Chav Nqus Tsev
Feem ntau cov khoom siv semiconductor sib dhos ua ke hauv qhov chaw nqus tsev uas qhov kev nplua nplua tsis txaus. Cov ntsuas ceramic muab qhov kev ntsuas qhov tseeb "qhuav" uas yuav tsis tawm cov pa roj lossis ua rau lub tshuab nqus tsev qias neeg, ua kom ntseeg tau tias cov khoom sab hauv tau sib dhos rau qhov kev kam rau siab sub-micron.
4. Kev Ntsuas Hluav Taws Xob Zaus Siab
Rau kev sim cov chips ceev ceev, txhua yam kev cuam tshuam magnetic lossis conductive los ntawm cov cuab yeej ntsuas tuaj yeem ua rau cov txiaj ntsig tsis sib xws. Alumina ceramic qhov xwm txheej tsis yog magnetic ua rau nws yog cov khoom siv zoo tshaj plaws rau cov khoom siv probe card thiab cov alignment gages.
5. Cov Kws Tshaj Lij Calibration Chav Huv Si
Hauv chav huv ISO Class 1, xeb yog ib yam khoom tsis pub ua. Cov ntsuas hlau xav tau cov roj zaj duab xis kom tiv thaiv kev oxidation, uas yog qhov txaus ntshai heev rau kev ua qias tuaj. Cov ntsuas ceramic tsis xav tau roj thiab tuaj yeem ntxuav nrog cawv isopropyl, tswj tau qhov profile "zero-particle" rau 10+ xyoo.
Qhov Zoo Tshaj Plaws ntawm "10-Xyoo"
Txawm hais tias cov hlau ntsuas yuav warp lossis hnav tom qab ob peb xyoos ntawm kev siv ntau, cov qauv molecular ntawm high-purity Alumina yog ruaj khov heev. Thaum siv ua Ceramic Square lossis Straight Edge, cov khoom siv qhov nyuaj (mus txog ntawm sapphire) tiv thaiv qhov microscopic degreasion uas feem ntau ua rau qhov tseeb "drift" dhau sijhawm.
Rau ib lub semiconductor OEM, qhov no txhais tau tias yuav txo tau 10 npaug ntawm cov nqi kho mus sij hawm ntev thiab muaj kev ntseeg siab ntau dua rau lub tshuab lub neej raug.
