Hav nyob ntawd! Raws li tus neeg muag khoom ntawm Graphite Base Susceptors, Kuv tau pom ua ntej yuav ua li cas cov khoom zoo nkauj ntawm graphite tuaj yeem ua lossis tawg cov khoom zoo hauv ntau daim ntawv thov. Hauv qhov blog no, kuv yuav dhia mus rau qhov Graphite Base Susceptors cuam tshuam cov khoom lag luam zoo thiab vim li cas lawv tseem ceeb heev hauv kev lag luam sib txawv.
Cia peb pib los ntawm kev nkag siab yooj yim ntawm Graphite Base Susceptors yog dab tsi. Lawv yog cov tseem ceeb ntawm graphite, cov khoom siv ntau yam paub txog nws cov thermal conductivity, tshuaj stability, thiab txhua yam muaj zog. Cov susceptors no yog tsim los nqus hluav taws xob hluav taws xob thiab hloov mus rau hauv tshav kub, uas tom qab ntawd siv rau hauv cov txheej txheem xws li tshuaj vapor deposition (CVD), lub cev vapor deposition (PVD), thiab lwm yam siab - kub manufacturing txheej txheem.
Ib qho ntawm cov chaw tseem ceeb uas Graphite Base Susceptors ua lub luag haujlwm loj yog hauv kev lag luam semiconductor. Semiconductor manufacturing yog txhua yam hais txog precision. Txawm tias qhov teeb meem me tshaj plaws tuaj yeem ua rau lub microchip tsis muaj txiaj ntsig. Graphite Base Susceptors yog siv hauv CVD cov txheej txheem los tsim cov yeeb yaj kiab nyias ntawm semiconductor wafers. Qhov zoo ntawm cov yeeb yaj kiab no ncaj qha cuam tshuam rau kev ua haujlwm ntawm cov khoom siv semiconductor.
Thaum Graphite Base Susceptor muaj cov khoom siv thermal zoo, nws ua kom ntseeg tau tias cov cua sov faib thoob plaws lub wafer zoo ib yam. Qhov no yog qhov tseem ceeb heev vim tias cov cua sov tsis sib xws tuaj yeem ua rau muaj kev hloov pauv hauv cov tuab thiab muaj pes tsawg leeg ntawm cov yeeb yaj kiab nyias. Piv txwv li, yog tias ib feem ntawm lub wafer kub dua li lwm qhov, qhov kev tso nyiaj yuav siab dua nyob rau hauv qhov chaw ntawd, ua rau cov yeeb yaj kiab tuab dua. Cov kev tsis sib xws no tuaj yeem ua rau muaj teeb meem kev ua haujlwm hluav taws xob hauv cov khoom semiconductor kawg, xws li kev hloov pauv hauv kev coj ua thiab kev tawg hluav taws xob.
Ntxiv nrog rau thermal uniformity, qhov zoo ntawm qhov chaw ntawm Graphite Base Susceptor kuj tseem ceeb. Ib tug du thiab huv si saum npoo yuav txo tau qhov muaj feem ntawm particle contamination thaum lub sij hawm deposition txheej txheem. Cov khoom ntawm cov susceptor tuaj yeem hloov mus rau lub wafer, tsim kev tsis xws luag hauv cov yeeb yaj kiab nyias. Raws li tus neeg xa khoom, peb ua kom peb cov Graphite Base Susceptors yog polished rau tus qauv siab thiab ua kom huv si ua ntej xa zaub mov kom txo tau cov kev pheej hmoo no.
Lwm qhov kev lag luam uas Graphite Base Susceptors tau siv dav yog kev lag luam photovoltaic (PV). Hauv kev tsim PV, lawv tau siv hauv cov txheej txheem xws li PECVD Graphite Boat. Cov txheej txheem PECVD yog siv los tso cov tshuaj tiv thaiv - cov txheej txheem cuam tshuam thiab cov txheej txheem passivation ntawm lub hnub ci. Cov txheej txheem no yog qhov tseem ceeb rau kev txhim kho kev ua haujlwm ntawm lub hnub ci hlwb los ntawm kev txo qis kev xav thiab tiv thaiv kev sib txuas ntawm cov cab kuj.
Graphite Base Susceptors nyob rau hauv PV kev lag luam yuav tsum muaj thermal shock kuj zoo heev. Thaum lub sij hawm PECVD txheej txheem, lub susceptor yog sai rhuab thiab txias. Yog tias nws tsis tuaj yeem tiv taus cov cua sov no, nws yuav tawg lossis tawg. Ib tug tawg los yog warped susceptor yuav tsis muab lub platform ruaj khov rau lub hnub ci hlwb, uas tuaj yeem ua rau cov txheej txheem tsis sib xws. Qhov no, nyob rau hauv lem, muaj feem xyuam rau tag nrho cov efficiency thiab durability ntawm lub hnub ci hlwb.
Ntxiv mus, kev ruaj ntseg tshuaj ntawm Graphite Base Susceptors yog qhov tseem ceeb hauv kev lag luam PV. Cov txheej txheem deposition feem ntau yog siv cov reactive gases. Cov tshuaj tiv thaiv kev ruaj ntseg yuav tsis hnov mob nrog cov pa roj carbon monoxide, kom ntseeg tau tias cov txheej txheem tso tawm ua tiav raws li qhov xav tau. Yog hais tias tus susceptor reacts nrog cov pa roj, nws tuaj yeem tso impurities rau hauv cov txheej txheem ib puag ncig, uas tuaj yeem ua paug rau lub hnub ci hlwb thiab txo lawv cov kev ua haujlwm.
Tsiv mus rau kev lag luam hluav taws xob tsim khoom, Graphite Base Susceptors yog siv hauv Graphite Chuck daim ntawv thov. Graphite chucks yog siv los tuav semiconductor wafers lossis lwm yam khoom siv hluav taws xob thaum ua haujlwm. Qhov zoo ntawm chuck ncaj qha cuam tshuam qhov tseeb ntawm kev ua haujlwm.
Lub qhov dej - tsim Graphite Base Susceptor rau chuck muab qhov chaw ruaj khov thiab tiaj tus rau wafer. Qhov no yog ib qho tseem ceeb rau cov txheej txheem xws li lithography, qhov twg yuav tsum tau ua kom zoo sib xws. Yog hais tias lub chuck nto tsis sib npaug, lub wafer yuav tsis tuav nyob rau hauv qhov tseeb txoj hauj lwm, ua rau misalignment thaum lithography. Qhov no tuaj yeem ua rau cov qauv tsis xws luag ntawm wafer, uas tuaj yeem cuam tshuam rau kev ua haujlwm ntawm cov khoom siv hluav taws xob zaum kawg.
Lub zog txhua yam ntawm Graphite Base Susceptor hauv chuck kuj tseem ceeb heev. Nws yuav tsum muaj peev xwm tiv taus lub zog clamping yam tsis muaj deforming. Yog hais tias tus susceptor deforms, nws tuaj yeem ua rau muaj kev ntxhov siab ntawm wafer, uas tuaj yeem ua rau tawg lossis lwm yam kev ua tsis tiav.
Hauv kev lag luam roj cell, Graphite Base Susceptors yog siv los tsim cov roj Cell Graphite Bipolar Phaj. Cov phaj bipolar yog ib qho tseem ceeb ntawm cov roj hlwb thaum lawv faib cov pa roj reactant, sau tam sim no, thiab muab kev txhawb nqa txhua yam.
Graphite Base Susceptors siv nyob rau hauv bipolar phaj manufacturing yuav tsum muaj hluav taws xob conductivity siab. Qhov no yog vim hais tias cov phaj bipolar yuav tsum tau siv hluav taws xob zoo los hloov cov hluav taws xob hluav taws xob tsim tawm hauv cov roj hluav taws xob. Ib tug susceptor uas tsis tshua muaj conductivity tuaj yeem ua rau muaj zog tiv thaiv nyob rau hauv daim hlau bipolar, uas txo cov efficiency tag nrho ntawm cov roj cell.
Tsis tas li ntawd, qhov porosity ntawm Graphite Base Susceptor cuam tshuam qhov zoo ntawm cov phaj bipolar. Yuav tsum muaj ib theem zoo ntawm porosity kom tso cai rau cov pa roj diffusion hauv cov phaj bipolar. Yog tias qhov porosity siab dhau los yog qis dhau, nws tuaj yeem cuam tshuam rau kev ua haujlwm ntawm cov roj hluav taws xob los ntawm kev txo cov roj ntws los yog ua rau cov pa paug.
Raws li tus neeg muag khoom ntawm Graphite Base Susceptors, peb niaj hnub ua haujlwm los txhim kho peb cov khoom zoo.
