Hav nyob ntawd! Kuv yog tus xa khoom ntawm Graphite Chuck, thiab hnub no kuv xav tham txog yuav ua li cas Graphite Chuck cuam tshuam nrog kev ntxhov siab. Kev ntxhov siab yog qhov loj hauv cov ntawv thov kev lag luam, thiab nkag siab tias peb cov khoom siv li cas tuaj yeem ua rau koj lub tswv yim zoo dua vim li cas lawv thiaj li ntseeg tau.
Graphite Chuck yog dab tsi?
Ua ntej tshaj, cia peb mus nrawm dua dab tsi Graphite Chuck yog. Graphite Chuck yog ib qho tseem ceeb hauv ntau cov txheej txheem kev lag luam. Nws yog tsim los ntawm siab - zoo graphite, uas yog lub npe hu rau nws zoo heev thermal thiab hluav taws xob conductivity, raws li zoo raws li nws siab zog thiab tsis kam mus corrosion. Hauv kev tsim khoom semiconductor, piv txwv li, Graphite Chuck yog siv los tuav wafers nyob rau hauv qhov chaw thaum muaj ntau yam txheej txheem xws li etching thiab deposition.
Yuav ua li cas Graphite Chuck Deal nrog Mechanical Stress?
Kev ntxhov siab ntawm txhua yam tuaj yeem los ntawm ntau qhov chaw, xws li clamping quab yuam, kev vibrations, thiab kev cuam tshuam. Graphite Chuck yog tsim los daws cov kev ntxhov siab no zoo.
Ib qho ntawm cov yam ntxwv tseem ceeb ntawm graphite uas pab nrog kev ntxhov siab yog nws lub zog siab - rau - qhov hnyav piv. Graphite yog qhov hnyav piv rau ntau cov hlau, tab sis nws tseem muaj lub zog zoo. Qhov no txhais tau hais tias nws tuaj yeem tiv taus lub zog tseem ceeb yam tsis muaj kev tawg lossis deforming yooj yim.
Lwm qhov tseem ceeb yog nws qhov yooj yim. Graphite muaj qee qhov elasticity, uas tso cai rau nws nqus tau qee qhov kev poob siab los ntawm kev cuam tshuam thiab kev vibrations. Thaum muaj qhov nrawm nrawm lossis kev vibration hauv cov txheej txheem tsim khoom, Graphite Chuck tuaj yeem hloov pauv me ntsis, txo qhov kev ntxhov siab ntawm wafer nws tuav thiab ntawm nws tus kheej.
Graphite kuj muaj cov coefficient tsawg ntawm kev sib txhuam. Qhov no yog qhov zoo thaum nws los txog rau clamping quab yuam. Thaum lub chuck yog siv los tuav lub wafer, qhov kev sib txhuam qis txhais tau hais tias muaj tsawg dua ntawm cov wafer slipping los yog puas vim yog lub zog ntau dhau. Nyob rau tib lub sijhawm, nws tseem tuaj yeem muab kev ruaj ntseg tuav ntawm lub wafer.
Thermal Stress thiab Graphite Chuck
Thermal stress yog lwm qhov kev txhawj xeeb loj hauv kev siv hauv kev lag luam, tshwj xeeb tshaj yog nyob rau hauv cov txheej txheem uas muaj kev hloov kub ceev. Graphite muaj qee cov khoom tshwj xeeb uas ua rau nws zoo - haum rau kev cuam tshuam nrog thermal stress.
Graphite muaj cov thermal expansion coefficient tsawg. Qhov no txhais tau hais tias thaum kub hloov pauv, Graphite Chuck tsis nthuav lossis cog lus ntau npaum li lwm cov ntaub ntawv. Nyob rau hauv tus txheej txheem uas chuck raug rau siab - qhov kub thiab txias ib puag ncig thaum lub sij hawm deposition thiab tom qab ntawd txias sai sai, cov khoom uas muaj thermal expansion coefficient yuav muaj kev ntxhov siab ntau hauv, uas tuaj yeem ua rau tawg lossis warping. Tab sis nrog graphite, cov teeb meem no tau txo qis.
Graphite kuj yog ib qho zoo heev thermal conductor. Nws tuaj yeem hloov cov cua sov sai sai ntawm thaj chaw uas nws tau tsim. Hauv kev tsim khoom semiconductor, piv txwv li, thaum lub sij hawm siab - lub zog etching txheej txheem, muaj cua sov ntau. Lub Graphite Chuck tuaj yeem ua qhov cua sov no tawm ntawm lub wafer, tiv thaiv overheating thiab txo thermal stress ntawm ob lub wafer thiab chuck nws tus kheej.
Chemical Stress Resistance
Ntxiv nrog rau cov neeg kho tshuab thiab thermal kev nyuaj siab, Graphite Chuck kuj yuav tsum tau nrog cov tshuaj lom neeg kev nyuaj siab. Hauv ntau cov txheej txheem kev lag luam, cov chuck raug rau ntau yam tshuaj, xws li cov kua qaub thiab cov kuab tshuaj.
Graphite yog heev resistant rau corrosion. Nws tuaj yeem tiv taus ntau yam tshuaj lom neeg yam tsis muaj kev puas tsuaj. Qhov no yog qhov tseem ceeb hauv kev siv xws li tshuaj vapor deposition (CVD), qhov twg cov chuck yog nyob rau hauv kev sib cuag nrog reactive gases thiab tshuaj. Cov tshuaj tiv thaiv ntawm graphite kom ntseeg tau tias lub chuck tswj nws cov qauv kev ncaj ncees nyob rau lub sijhawm, txawm tias nyob rau hauv ib puag ncig hnyav tshuaj.
Sib piv Graphite Chuck nrog lwm cov ntaub ntawv
Cia peb saib sai li cas Graphite Chuck piv nrog lwm cov ntaub ntawv uas feem ntau siv hauv cov ntawv zoo sib xws.
Cov hlau feem ntau siv rau hauv kev lag luam chucks, tab sis lawv muaj qee qhov tsis zoo thaum nws los txog rau kev ntxhov siab. Cov hlau feem ntau muaj cov thermal expansion coefficient ntau dua li graphite, uas txhais tau hais tias lawv muaj feem cuam tshuam rau thermal stress - cov teeb meem ntsig txog. Lawv kuj hnyav dua, uas tuaj yeem ua rau muaj kev ntxhov siab ntawm txhua qhov system.
Ceramics yog lwm qhov kev xaiv, tab sis lawv nkig. Lawv tuaj yeem tawg yooj yim nyob rau hauv kev ntxhov siab, tshwj xeeb tshaj yog los ntawm kev cuam tshuam lossis kev vibrations. Graphite, ntawm qhov tod tes, yog hloov tau yooj yim dua thiab tsis tshua muaj kev tawg nyob rau hauv cov xwm txheej zoo sib xws.
Cov ntawv thov thiab qhov tseem ceeb ntawm Kev Tiv Thaiv Kev Nyuaj Siab
Lub peev xwm ntawm Graphite Chuck los daws kev ntxhov siab ua rau nws haum rau ntau yam kev siv.
Hauv kev lag luam hnub ci, PECVD Graphite Nkoj feem ntau siv nrog Graphite Chuck. Lub chuck pab tuav cov silicon wafers nyob rau hauv qhov chaw thaum lub sij hawm plasma - enhanced tshuaj vapor deposition (PECVD) txheej txheem. Qhov kev ntxhov siab - tuav lub peev xwm ntawm Graphite Chuck xyuas kom meej tias cov wafers tau tuav ruaj ntseg thiab cov txheej txheem tso tawm raug ua tiav, ua rau siab - lub hnub ci zoo.
Hauv kev lag luam roj hluav taws xob, Roj Cell Graphite Bipolar Plate yog lwm daim ntawv thov tseem ceeb. Lub Graphite Chuck tuaj yeem siv los tuav cov phaj bipolar thaum lub sijhawm tsim khoom.
