Thaum lub tshuab EUV lithography ua haujlwm hauv lub Hoobkas semiconductor, nws lub hauv paus yuav tsum tuav cov kev kam rau siab nanometer thaum tshem tawm kev co los ntawm cov khoom siv ze. Qhov kev xav tau ruaj khov heev ntawd piav qhia vim li cas cov neeg tsim khoom loj ntseeg cov khoom siv tsis zoo: granite ntuj. Lub pob zeb no, tsim ntau lab xyoo tob hauv lub ntiaj teb lub plhaub, tau dhau los ua qhov tseem ceeb hauv kev tsim khoom raug. Nws qhov kev sib xyaw ua ke ntawm kev ruaj khov thermal, kev co damping, thiab qhov tseeb ntev ua rau nws yog cov khoom siv xaiv rau cov khoom siv uas microns - thiab nanometers nce ntxiv - tseem ceeb.
Lub Physics Tom Qab Granite Kev Ua Tau Zoo
Granite muaj peev xwm ua tau zoo vim yog cov khoom uas niaj hnub nim no tseem siv tau. Nws qhov coefficient ntawm thermal expansion tsuas yog 0.6–1.2 × 10⁻⁶/°C, kwv yees li kaum npaug qis dua hlau. Qhov thermal inertia no txhais tau tias cov khoom granite hloov pauv tsawg kawg nkaus thaum qhov kub thiab txias hloov pauv, qhov tseem ceeb hauv cov chaw uas semiconductor fabrication xav tau kev ruaj khov ntsuas hauv billionths ntawm ib 'meter'.
Cov yam ntxwv ntawm kev co ntawm cov khoom siv kuj tseem ceeb ib yam. Hauv qhov ntau zaus 50–500 Hz uas feem ntau siv rau hauv cov khoom siv tsim khoom, granite nqus thiab tshem tawm 95% ntawm lub zog co. Nws qhov piv ntawm 0.012–0.015 ntau dua li cov hlau cam khwb cia los ntawm kaum feem pua. Thaum lub tshuab CNC spindle ncav cuag 20,000 RPM lossis lub tshuab wafer ua haujlwm sai, qhov kev co no tiv thaiv kev sib tsoo ntawm cov cuab yeej, txo cov qhov tsis zoo ntawm qhov chaw, thiab ua rau lub neej ntawm cov cuab yeej txiav ntev dua.
Cov kws ua haujlwm ua haujlwm nrog cov tshuab granite qhia txog kev txo qis txog li 40% ntawm kev co ntawm cov cuab yeej thaum lub sijhawm ua haujlwm milling precision. Ua ke nrog 60% tsawg dua thermal drift piv rau cov qauv hlau, cov khoom no ua rau cov chaw tsim khoom tuaj yeem thawb qhov ceev ntawm spindle thiab cov nqi pub siab dua thaum tswj hwm kev kam rau siab. Qhov tshwm sim: qhov tiav ntawm qhov chaw zoo dua, lub sijhawm voj voog sai dua, thiab tsawg dua qhov chaw tsis lees paub.
Kev Tsim Khoom Semiconductor: Qhov twg Nanometers yog qhov qub
Kev tsim cov chip niaj hnub no ua rau muaj kev xav tau ntau yam rau cov khoom siv kho tshuab. Cov txheej txheem lithography siab heev xav tau cov qauv hauv paus uas tswj qhov rov ua dua qhov chaw hauv qab 5 nanometers. Kev ua tau raws li cov lus qhia no xav tau cov ntaub ntawv uas tsis yooj yim khoov, khoov, lossis xa cov kev co zoo li cov hlau ua.
Cov khoom siv Photolithography sawv cev rau daim ntawv thov uas xav tau tshaj plaws. Cov tshuab EUV siv rau hauv kev tsim cov chips tshiab ua haujlwm nrog cov theem wafer uas yuav tsum tso thiab rov tso nrog qhov tseeb nanometer.cov hauv paus granite, cov kev taw qhia, thiab cov khoom theem txhawb nqa cov kab ke no muab lub hauv paus ruaj khov, tsis muaj kev co uas ua rau muaj kev ua tau zoo li no. Cov neeg muag khoom loj xws li ASML teev cov khoom granite thoob plaws lawv cov platforms siab tshaj plaws.
Cov txheej txheem tshuaj xyuas wafer nyob ntawm cov platform granite thaum pom cov qhov tsis zoo uas tib neeg lub qhov muag tsis pom. Cov cuab yeej tshuaj xyuas qhov tsis zoo, cov txheej txheem tshuaj xyuas qhov muag, thiab cov cuab yeej tshuaj xyuas electron beam txhua yam xav tau cov platform ntsuas ruaj khov. Cov lus qhia txog qhov tiaj tiaj rau cov ntawv thov no feem ntau ncav cuag ≤2 μm / m², nrog rau qhov xav tau ntawm qhov roughness ntawm Ra ≤0.2 μm - qhov chaw du txaus uas lub teeb nws tus kheej ua haujlwm kwv yees tau thoob plaws lawv cov chaw.
Cov khoom siv tshuaj lom neeg planarization (CMP) tau txais txiaj ntsig los ntawm granite lub vibration damping thaum lub sijhawm polishing uas tsim cov wafer nto tiaj tiaj. Lub siab thiab kev tswj hwm kev txav mus los uas cov kab ke no xav tau nyob ntawm lub hauv paus tshuab uas tsis ua rau muaj kev co me me thaum lub sijhawm ua haujlwm.
Dhau li ntawm cov txheej txheem tseem ceeb, cov khoom siv wafer dicing thiab etching, laser interferometer bases rau metrology daim ntawv thov, thiab wafer handling robots tag nrho suav nrog cov khoom granite. Cov caj npab neeg hlau precision uas thauj cov wafers ntawm cov cuab yeej ua haujlwm caij ntawm granite guide rails uas nws qhov tiaj tus thiab ruaj khov ua kom muaj qhov chaw raug yam tsis muaj kev hnav khaub ncaws ua rau ntau xyoo ntawm kev ua haujlwm tas mus li.
Cov Cuab Yeej Siv Tshuab CNC: Kev Ceev, Kev Tseeb, thiab Qhov Zoo Ntawm Qhov Chaw
Cov ntawv thov granite precision uas thawj zaug los rau hauv siab rau ntau tus engineers yog CNC tshuab cov cuab yeej. Cov chaw machining ua haujlwm siab dua qhia granite ua lawv cov khoom siv hauv paus, tshwj xeeb tshaj yog rau kev ua haujlwm qhov twg qhov tiav ntawm qhov chaw thiab qhov ntev raug dua qhov nrawm tshem tawm hlau.
Cov tshuab ntsuas sib koom ua ke (CMMs), cov cuab yeej uas txheeb xyuas seb cov khoom tsim tawm puas ua tau raws li cov lus qhia, yuav luag tsuas yog siv cov phaj granite thiab cov hauv paus xwb. Kev ruaj khov ntawm cov granite ua kom ntseeg tau tias cov kev ntsuas uas tau ua thaum sawv ntxov phim cov uas tau ua tom qab lub tshuab tau khiav ntau teev - qhov sib xws tsis yooj yim sua nrog cov ntaub ntawv uas nthuav dav thiab cog lus ntau nrog kev hloov pauv kub.
Cov khoom siv khawb PCB nthuav tawm lwm qhov kev siv zoo heev. Cov laug cam niaj hnub muaj ntau txhiab lub qhov nrog qhov ntsuas qhov kam rau ua hauv micrometers. Lub hauv paus tshuab granite muab lub platform ruaj khov, tsis muaj kev co uas tso cai rau cov taub hau khawb ceev ceev los tsim cov qhov huv si, qhov chaw raug ntawm tus nqi ntau dua 600 zaug ib feeb.
Cov tshuab txiav laser thiab cov tshuab ua haujlwm tau zoo ib yam. Cov cua sov uas tsim thaum lub sijhawm ua laser ua rau muaj kev ntxhov siab thermal hauv cov khoom ua haujlwm thiab cov qauv tshuab ib yam. Lub hauv paus granite nqus cov teebmeem no, tswj kev ua kom pom tseeb thiab txiav zoo thoob plaws hauv kev tsim khoom ntev.
Rau cov khw muag khoom uas nrhiav kev kam rau siab tshaj plaws hauv kev ua cov cuab yeej thiab pwm, kev ua cov khoom siv aerospace, lossis kev tsim cov khoom siv kho mob, cov tshuab CNC granite txaj muaj cov txiaj ntsig uas cov hlau thiab cov hlau cam khwb cia tsis tuaj yeem phim. Kev sib xyaw ua ke ntawm kev co damping, thermal stability, thiab kev ncaj ncees ntev ntev ua rau muaj kev txhim kho zoo hauv qhov zoo ntawm cov khoom tiav.
Kev Sib Piv Cov Khoom Siv: Vim Li Cas Granite Sawv Ib Leeg
Cov engineers xaiv cov ntaub ntawv tseem ceeb raucov khoom siv precisionFeem ntau ntsuas granite piv rau peb txoj kev xaiv ib txwm muaj: hlau cam khwb cia, hlau, thiab txhuas. Txhua yam muaj qee qhov zoo, tab sis granite ua ke ntawm cov yam ntxwv ua pov thawj tias haum rau cov ntawv thov siab.
| Vaj tse | Pob zeb granite | Hlau cam khwb cia | Hlau | Aluminium |
|---|---|---|---|---|
| Kev Nthuav Dav Kub (×10⁻⁶/°C) | 4.5 | 10-12 | 12 | 23 |
| Qhov piv ntawm kev co | 0.012-0.015 | 0.001 | 0.0006 | 0.0001 |
