Qhov kev tsav tsheb tsis tu ncua rau kev ua kom me me thiab kev ua tau zoo hauv cov thev naus laus zis niaj hnub no - los ntawm cov vaj huam sib luag siab heev mus rau cov cuab yeej siv thev naus laus zis tshiab - tau thawb cov kev txwv ntawm cov khoom siv engineering ib txwm muaj. Hauv kev nrhiav kev ua kom raug sub-micron thiab txawm tias nanometer-level, cov engineers pheej tig mus rau cov khoom siv zoo tshaj plaws hauv geological millennials: granite ntuj. Lub pob zeb zoo li txo hwj chim no tau dhau los ua lub hauv paus tsis sib tham rau cov khoom siv uas tsim peb lub neej yav tom ntej digital.
Qhov kev thov kom muaj kev ruaj khov thiab qhov tseeb hauv cov lag luam xws li kev tsim khoom siv semiconductor thiab kev ntsuas siab heev qhia txog vim li cas cov khoom siv granite precision tseem ceeb dua. Tsis zoo li cov hlau, uas yooj yim rau kev nthuav dav thermal thiab kev co, cov granite dub muaj cov khoom siv lub cev tshwj xeeb uas tsim ib puag ncig zoo tagnrho rau kev ua haujlwm ultra-precision.
Lub hauv paus ntawm Flat Panel Display Technology
Kev tsim cov vaj huam sib luag niaj hnub no - tshwj xeeb yog cov uas siv Amorphous Silicon (a-Si) thiab Low-Temperature Polycrystalline Silicon (LTPS) technologies - xav tau cov tshuab uas tuaj yeem tswj tau qhov tiaj tiaj thiab qhov tseeb ntawm qhov chaw loj. Qhov no yog qhov uas cov khoom siv granite rau a-Si Array thiab cov granite precision rau LTPS Array khoom siv tseem ceeb heev.
Thaum tsim cov iav loj rau cov zaub, txawm tias qhov kev hloov pauv me me hauv lub tshuab cov qauv tuaj yeem txhais tau tias muaj qhov tsis zoo thiab poob qis. Granite qhov coefficient qis heev ntawm thermal expansion (kwv yees li ib nrab ntawm cov hlau) ua kom ntseeg tau tias lub tshuab cov qauv tseem ruaj khov txawm tias thaum muaj qhov kub hloov pauv me me hauv chav huv. Ntxiv mus, nws lub peev xwm damping sab hauv zoo heev - siab dua li hlau cam khwb cia lossis hlau - yog qhov tseem ceeb rau kev ua kom cov kev co me me tsis zoo. Cov kev co no, uas tej zaum yuav tsis pom rau tib neeg kov, tuaj yeem ua rau muaj kev puas tsuaj rau cov txheej txheem lithography, etching, lossis deposition siv los tsim cov transistors me me thiab circuits ntawm array. Los ntawm kev tshem tawm cov zog no sai sai, granite bases, beams, thiab gantry Cheebtsam ua kom ntseeg tau tias cov theem rhiab heev txav mus nrog cov kua, rov ua dua qhov tseeb xav tau rau kev tsim khoom siab, siab-qib siab ntawm cov zaub daws teeb meem siab.
Qhov tawv ntawm granite kuj txhais tau tias cov khoom siv tshuab tuaj yeem txhawb nqa cov khoom hnyav - xws li cov kab ke loj, cov chaw nqus tsev, thiab cov taub hau ua haujlwm - nrog qhov tsawg kawg nkaus deflection, lav qhov kev ua tau zoo thoob plaws hauv tag nrho cov txheej txheem ua haujlwm.
Pab kom muaj kev tshawb pom tseeb txog kev tshawb fawb nrog Metrology
Tsis tas li ntawm kev tsim khoom, cov yam ntxwv tshwj xeeb ntawm cov pob zeb granite uas raug ntsuas yog qhov tseem ceeb hauv kev tshawb fawb tseem ceeb thiab kev ntsuas. Ib qho piv txwv zoo yog nws lub luag haujlwm hauv cov cuab yeej siv tshuaj ntsuam xyuas siab, tshwj xeeb tshaj yog cov pob zeb granite raug ntsuas rau cov khoom siv XRD (X-ray Diffraction).
Kev Siv X-ray Diffraction yog ib txoj kev siv zog los txiav txim siab txog cov qauv atomic thiab molecular ntawm ib lub crystal. Qhov kev ntsuas qhov tseeb uas xav tau rau goniometer—lub cuab yeej uas tig cov qauv thiab lub tshuab ntes X-ray—yog qhov zoo kawg nkaus. Txhua qhov kev txav lossis kev co uas cuam tshuam rau lub kaum sab xis ntawm qhov tshwm sim lossis kev kuaj pom tuaj yeem ua rau cov ntaub ntawv nyuaj uas tau sau tsis raug.
Lub platform metrology ntawm lub kaw lus XRD siab kawg yuav tsum tsis muaj thermal drift thiab muaj peev xwm txhawb nqa cov khoom siv kho qhov muag thiab cov khoom siv kho tshuab nrog kev ruaj khov tshwj xeeb. Precision granite muab lub dav hlau zoo meej thiab dimensionally inert reference uas tsim nyog rau kev ua tiav cov kev daws teeb meem angular uas xav tau rau kev tshuaj xyuas cov khoom siv siab heev. Nws cov khoom tsis yog magnetic yog ib qho txiaj ntsig ntxiv, ua kom ntseeg tau tias cov sensors hluav taws xob rhiab heev thiab cov tshuab tswj electromagnetic hauv cov khoom siv tsis cuam tshuam los ntawm cov hlau nplaum seem, ib qho teeb meem tshwm sim nrog cov hlau ferrous.
Cov Zoo Tshaj Plaws ntawm Pob Zeb Ntuj hauv Lub Caij Nyoog Precision
Qhov kev vam meej ntawm granite hauv cov ntawv thov no tsis yog qhov xwm txheej; nws yog qhov tshwm sim ncaj qha ntawm nws cov khoom siv science:
-
Kev Ruaj Ntseg ntawm Qhov Ntev: Tom qab kev laus ntawm geological rau ntau lab xyoo, cov qauv sab hauv ntawm cov granite dub zoo yog sib xws thiab txo kev ntxhov siab, muab kev txav mus los sab hauv ze li ntawm xoom dhau sijhawm, uas yog qhov tseem ceeb rau kev tswj hwm kev ntsuas.
-
Kev Nthuav Dav Thermal Qis: Nws qhov kev teb tsawg kawg nkaus rau qhov kev hloov pauv kub tswj tau geometry, ib qho khoom tseem ceeb rau txhua txoj kev ua haujlwm raug ua haujlwm hauv kev tswj hwm, tab sis tsis yog isothermal zoo meej, tej yam kev mob.
-
Kev Tiv Thaiv Kev Co: Cov khoom xyaw ntuj tsim muaj cov khoom siv tiv thaiv kev co zoo heev, txo cov suab nrov ntawm lub tshuab sai dua thiab zoo dua li cov hlau tsim.
-
Tsis Muaj Corrosive thiab Tsis Muaj Magnetic: Granite yog xeb-pov thawj thiab tsis muaj magnetic, ua kom yooj yim rau kev txij nkawm thiab tshem tawm cov teeb meem cuam tshuam electromagnetic uas tuaj yeem ua rau cov cuab yeej rhiab heev.
Los ntawm kev siv cov khoom no, cov chaw tsim khoom tuaj yeem ua tiav qhov kev kam rau siab micron- thiab nanometer-level uas tsim nyog los txhawb nqa nthwv dej tom ntej ntawm kev tsim kho tshiab. Kev txav mus los ntawm cov hlau ib txwm mus rau kev tsim kho tshwj xeeb, cov granite foundation ultra-flat sawv cev rau kev hloov pauv tseem ceeb hauv kev tsim kho siab-kev lees paub tias rau kev ruaj khov tiag tiag, qee zaum cov ntaub ntawv qub tshaj plaws yog qhov zoo tshaj plaws. Rau txhua lub tuam txhab cog lus rau kev ua tiav qhov tseeb tsis sib xws hauv a-Si, LTPS, lossis cov khoom siv metrology siab heev, precision granite tsis yog tsuas yog kev xaiv khoom siv xwb; nws yog qhov tsim nyog sib tw.
