Thaum nws los txog rau semiconductor thiab photovoltaic industries, Plasma-Enhanced Chemical Vapor Deposition (PECVD) yog cov txheej txheem siv dav rau kev tso cov yeeb yaj kiab nyias ntawm ntau lub substrates. Ib qho tseem ceeb ntawm cov txheej txheem PECVD yog lub nkoj graphite, uas yog lub luag haujlwm rau cov substrates thaum lub sij hawm deposition. Raws li tus thawj coj PECVD graphite nkoj xa khoom, peb nkag siab qhov tseem ceeb ntawm kev nyab xeeb thaum siv cov nkoj graphite no. Hauv tsab ntawv tshaj tawm no, peb yuav tham txog qhov tseem ceeb ntawm kev tiv thaiv kev nyab xeeb uas yuav tsum tau coj los ua kom muaj kev nyab xeeb thiab ua haujlwm tau zoo PECVD.
1. Cov Khoom Siv Tiv Thaiv Tus Kheej (PPE)
Ua ntej tuav lub nkoj PECVD graphite, nws tseem ceeb heev uas yuav tsum hnav cov khoom tiv thaiv tus kheej tsim nyog. Qhov no suav nrog tsom iav kev nyab xeeb los tiv thaiv koj ob lub qhov muag los ntawm tej yam muaj peev xwm splashes los yog ya cov khib nyiab. Tshuaj- cov hnab looj tes tiv thaiv kuj tseem tsim nyog los tiv thaiv kev sib cuag ncaj qha nrog cov tshuaj siv hauv txheej txheem PECVD. Cov hnab looj tes no yuav tsum tau ua los ntawm cov ntaub ntawv uas tuaj yeem tiv taus qhov corrosive ntawm cov tshuaj muaj feem xyuam. Tsis tas li ntawd, yuav tsum hnav lub tsho loj los yog cov khaub ncaws tiv thaiv kom tiv thaiv koj lub cev los ntawm kev nchuav thiab tawg.
2. Kev tuav thiab khaws cia
Thaum tuav lub nkoj PECVD graphite, nws yog ib qho tseem ceeb uas yuav tsum tau ua nrog kev saib xyuas. Graphite yog cov khoom siv nkig, thiab kev tuav rawv tuaj yeem ua rau tawg lossis tawg, uas tuaj yeem cuam tshuam kev ua haujlwm ntawm lub nkoj thiab ua rau muaj kev nyab xeeb. Ib txwm siv cov txheej txheem nqa kom zoo thiab tsis txhob poob lossis tsoo lub nkoj.
Thaum lub sij hawm cia, lub nkoj graphite yuav tsum tau khaws cia rau hauv qhov chaw huv, qhuav. Kev ya raws tuaj yeem ua rau cov graphite oxidize, uas tuaj yeem txo nws txoj sia thiab cuam tshuam rau qhov zoo ntawm cov yeeb yaj kiab nyias. Nws kuj tseem pom zoo kom khaws lub nkoj rau hauv ib lub thawv ntim khoom tshwj xeeb los tiv thaiv nws los ntawm kev puas tsuaj los ntawm lwm yam khoom.
3. Kev tu thiab tu
Kev tu thiab tu lub nkoj PECVD graphite tsis tu ncua yog qhov tseem ceeb rau nws txoj kev nyab xeeb thiab ua haujlwm tau zoo. Sij hawm dhau mus, lub nkoj tuaj yeem khaws cov khoom tso tawm los ntawm cov txheej txheem nyias nyias, uas tuaj yeem cuam tshuam rau nws qhov kev ua tau zoo thiab ua rau muaj teeb meem kev nyab xeeb.
Txhawm rau ntxuav lub nkoj graphite, siv cov tshuaj ntxuav me me thiab txhuam mos. Tsis txhob siv cov khoom siv abrasive lossis cov tshuaj hnyav, vim tias cov no tuaj yeem ua rau lub ntsej muag graphite puas. Tom qab ntxuav, yaug lub nkoj kom huv si nrog dej deionized thiab qhuav kom huv si ua ntej siv.
Ntxiv nrog rau kev tu, yuav tsum tau kuaj xyuas tsis tu ncua los xyuas seb puas muaj kev puas tsuaj lossis hnav. Yog tias pom muaj kab nrib pleb, chips, lossis lwm yam tsis xws luag, lub nkoj yuav tsum tau hloov tam sim ntawd kom tsis txhob muaj kev puas tsuaj ntxiv thiab ua kom muaj kev nyab xeeb.
4. Kev nyab xeeb tshuaj
Cov txheej txheem PECVD feem ntau suav nrog kev siv ntau yam tshuaj, xws li silane, ammonia, thiab nitrogen. Cov tshuaj no tuaj yeem tsim kev puas tsuaj yog tias tsis ua haujlwm zoo.
Thaum ua hauj lwm nrog cov tshuaj, nws yog ib qho tseem ceeb kom ua raws li tag nrho cov txheej txheem kev nyab xeeb thiab cov txheej txheem. Qhov no suav nrog kev siv qhov cua kom zoo los tiv thaiv kev sib sau ntawm cov pa phem, hnav PPE tsim nyog, thiab khaws cov tshuaj hauv qhov chaw ruaj ntseg.
Tsis tas li ntawd, nws yog ib qho tseem ceeb uas yuav tsum paub txog cov kev phom sij uas cuam tshuam nrog txhua yam tshuaj lom neeg thiab kom muaj cov khoom siv kev nyab xeeb tsim nyog ntawm tes, xws li cov tua hluav taws thiab da dej thaum muaj xwm ceev.
5. Kev nyab xeeb hluav taws xob
Cov khoom siv PECVD siv ua ke nrog lub nkoj graphite feem ntau yog siv hluav taws xob. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tsum tau ceev faj txog kev tiv thaiv hluav taws xob tsim nyog.
Ua ntej siv cov khoom siv, xyuas kom meej tias nws yog hauv av kom zoo thiab txhua qhov kev sib txuas hluav taws xob muaj kev ruaj ntseg. Tsis txhob kov tej yam hluav taws xob nrog tes ntub dej lossis thaum sawv ntsug hauv qhov chaw ntub dej.
Tsis tas li ntawd, nws yog ib qho tseem ceeb uas yuav tsum ua raws li tag nrho cov txheej txheem kev nyab xeeb hluav taws xob thiab cov txheej txheem muab los ntawm cov chaw tsim khoom siv. Yog tias muaj teeb meem hluav taws xob, cov khoom siv yuav tsum raug kaw tam sim ntawd thiab yuav tsum tau hu ib tus kws kho hluav taws xob tsim nyog los kho.
6. Kev cob qhia thiab kev kawm
Kev cob qhia kom raug thiab kev kawm yog qhov tseem ceeb rau kev ua kom muaj kev nyab xeeb ntawm kev siv lub nkoj PECVD graphite. Txhua tus neeg ua haujlwm koom nrog hauv cov txheej txheem PECVD yuav tsum tau txais kev cob qhia zoo txog kev tuav, tu, tu, thiab cov txheej txheem kev nyab xeeb cuam tshuam nrog lub nkoj graphite.
Qhov kev cob qhia no yuav tsum suav nrog ob qho tib si theoretical thiab cov tswv yim, thiab yuav tsum tau hloov kho tsis tu ncua kom muaj kev cuam tshuam txog kev hloov pauv ntawm cov cuab yeej lossis cov txheej txheem.
7. Kev Npaj Thaum Muaj Xwm Ceev
Txawm hais tias ua txhua yam kev tiv thaiv kev nyab xeeb tsim nyog, kev kub ntxhov tseem tuaj yeem tshwm sim. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tsum muaj kev npaj npaj xwm txheej ceev.
Txoj kev npaj no yuav tsum muaj cov txheej txheem los teb rau ntau yam xwm txheej kub ntxhov, xws li hluav taws kub, hluav taws xob, thiab hluav taws xob poob. Nws tseem yuav tsum suav nrog qhov chaw ntawm cov khoom siv thaum muaj xwm ceev, xws li tua hluav taws, da dej thaum muaj xwm ceev, thiab cov khoom siv pab thawj zaug.
Tsis tas li ntawd, txhua tus neeg ua haujlwm yuav tsum raug cob qhia txog kev npaj npaj thaum muaj xwm txheej ceev thiab yuav tsum paub yuav ua li cas thaum muaj xwm txheej ceev.
