Nyob rau hauv lub ntiaj teb no ntawm semiconductor manufacturing, qhov twg nta yog ntsuas nyob rau hauv nanometers, lub hauv paus ntawm lub lithography tshuab yog nws cov cuab tam tseem ceeb tshaj plaws. Precision granite Cheebtsam muab qhov tsim nyog thermal stability thiab kev co damping xav tau rau wafer stepping thiab scanning. Txawm li cas los xij, qhov ua tau zoo ntawm txawm tias qhov siab tshaj - zoo lithography granite platform tuaj yeem cuam tshuam los ntawm kev teeb tsa tsis zoo.
Ntawm Unparalleled Group, peb muab lub ntiaj teb -chav kawm granite kev daws teeb meem rau lub ntiaj teb no semiconductor kev lag luam. Cov lus qhia no qhia txog tus qauv 5- cov txheej txheem ua haujlwm ua haujlwm kom ntseeg tau tias koj cov cuab yeej ua tiav qhov tseeb sub-micron txij hnub ib.
Kauj Ruam 1: Cleanroom Environmental Stabilization
Ua ntej lub hauv paus granite txawm kov hauv pem teb, ib puag ncig yuav tsum tau tswj.
Kub Equilibrium: Granite muaj siab thermal inertia. Cov Cheebtsam yuav tsum nyob rau hauv chav kawm 10/100 chav huv huv rau tsawg kawg 24-48 teev kom ncav cuag thermal sib npaug nrog cov huab cua ambient (22 ± 0.1℃yog tus qauv kev lag luam).
Kev Npaj Nto: Siv cov khoom tshwj xeeb uas tsis yog- cov tshuaj ntxuav kom tshem tawm cov roj tiv thaiv kev thauj mus los. Txhua qhov microscopic particle sab laug ntawm cov ntsiab lus mounting tuaj yeem ua rau "tilt" uas txhais tau tias yog qhov yuam kev loj heev nyob rau sab saum toj ntawm qhov kho qhov muag.
Kauj ruam 2: Precision Leveling & Ntau -Point Support
Semiconductor platforms feem ntau siv 3-point thawj qhov kev txhawb nqa los tiv thaiv kev ntxhov siab sab hauv, ntxiv los ntawm cov ntsiab lus pabcuam rau kev ruaj ntseg.
Cov Txheej Txheem: Siv cov qib siab - cov qib hluav taws xob muaj tseeb (sensitivity ntawm 0.001 mm / m) los tsim lub dav hlau thawj.
Lub Hom Phiaj: Tshem tawm "twist" hauv granite. Rau lub hauv paus loj lithography, qhov flatness yuav tsum tau txheeb xyuas nyob rau hauv nws qhov kawg loaded lub xeev kom account rau tej yam ntxwv deflection.
Kauj Ruam 3: Cov khoom sib xyaw ua ke thiab Torque Sequencing
Thaum mounting cua bearings, linear motors, los yog ceramic qhia mus rau granite, qhov sib lawv liag fastening yog ib qho tseem ceeb heev.
Kev zam kev ntxhov siab: Siv lub hnub qub - qauv torque sib lawv liag ntawm txhua qhov ntsia hlau ntsia.
Insert Integrity: Xyuas kom meej tias 304 stainless hlau los yog epoxy - cov ntaub ntawv sib khi yog huv. Tshaj -torquing tuaj yeem ua rau micro- pob txha hauv granite nyob ib puag ncig ntawm qhov ntxig, ua rau lub sijhawm ntev - drift.
Kauj ruam 4: Dynamic Vibration Test (Modal Analysis)
Lub platform zoo li qub tsis txaus; cov granite yuav tsum ua nyob rau hauv lub siab -acceleration loads ntawm ib tug wafer theem.
Kev Ntsuas: Siv accelerometers los ua kev tshuaj ntsuam xyuas. Qhov no tau lees paub tias cov khoom damping ntawm lithography granite platform tau zoo neutralizing cov zaus tsim los ntawm cov cuab yeej txav chaw.
Kos: Xyuas kom tseeb tias granite lub ntuj zaus tsis cuam tshuam nrog servo-voj zaus ntawm cov tswj cov lus tsa suab.
Kauj ruam 5: Thaum kawg Geometric Verification & Calibration
Cov kauj ruam kawg yog "Golden Inspection" siv laser interferometry.
Linearity & Squareness: Siv lub laser interferometer los ntsuas qhov kev mus los ntawm cov axes hla granite nto.
Cov ntaub ntawv: Tsim daim ntawv qhia kev ntsuas zaum kawg. Qhov digital ntxaib ntawm granite's geometry no tuaj yeem raug programmed rau hauv cov khoom siv software los them nyiaj rau lwm qhov sub-micron deviations.
Vim li cas Precision Matters hauv Lithography
Rau cov khoom lag luam semiconductor thiab cov chaw ua haujlwm huv huv, kev teeb tsa ntawm cov khoom siv granite yog qhov ua haujlwm siab - ceg txheem ntseeg. Kev ua yuam kev hauv qib lossis tsis ua haujlwm hauv thermal stabilization tuaj yeem ua rau "kev ua yuam kev overlay," txo wafer tawm los thiab raug nqi ntau lab hauv kev tsim khoom ploj.
Los ntawm kev ua raws li tus qauv no 5- cov lus qhia kauj ruam, koj txo qis kev pheej hmoo ntawm kev teeb tsa thiab ua kom ROI ntawm koj lub rooj sib txoos ua haujlwm siab.
