Tus Nqi Tshwj Xeeb ntawm Green Silicon Carbide Micropowder hauv Kev Lag Luam Semiconductor
Kev lag luam semiconductor yeej ib txwm yog lub npe hu ua thev naus laus zis siab, nrog rau cov neeg feem ntau tham txog cov ncauj lus siab xws li cov tshuab photolithography thiab kev tsim cov chip. Txawm li cas los xij, hauv kev lag luam no, qee cov ntaub ntawv uas zoo li tsis tseem ceeb ua lub luag haujlwm tseem ceeb.Ntsuab silicon carbide micropowderyog ib qho khoom siv zoo li no. Niaj hnub no, cia peb tham txog cov khoom siv tshwj xeeb no, ua haujlwm ntsiag to los ntawm kev tsim khoom semiconductor.
Cia kuv pib nrog ib zaj dab neeg nthuav. Xyoo tas los, kuv tau mus koom ib qho kev lag luam semiconductor. Ntawm ib lub rooj muag khoom uas tsis tshua muaj neeg pom, ntau tus engineers tau sib tham txog ib daim khoom siv sib tsoo. Mloog zoo, kuv hnov lawv hais ntau zaus txog "ntsuab silicon carbide micropowder." Kuv xav tsis thoob thaum lub sijhawm ntawd; nws zoo li cov khoom siv abrasive ib txwm muaj, yog li nws yuav txuas nrog cov semiconductors precision li cas? Tom qab ntawd, kuv pom tias hauv kev lag luam no, cov khoom siv yooj yim dua, nws tseem ceeb dua.
Dab tsi yog silicon carbide micropowder tiag? Hais yooj yim xwb, nws yog ib yam khoom siv tawv heev uas tib neeg ua, uas tau yaj hauv lub cub hluav taws xob kub siab los ntawm cov khoom siv raw xws li xuab zeb quartz thiab roj av coke. Nws tau txais nws lub npe los ntawm nws qhov huv siab thiab xim ntsuab tshwj xeeb. Tsis txhob saib tsis taus cov khoom me me no; lawv qhov tawv yog qhov thib ob tsuas yog pob zeb diamond, tab sis lawv muaj kev ruaj khov thermal zoo dua thiab kev tsis muaj tshuaj lom neeg.
Hauv kev tsim khoom semiconductor, qhov tiaj tiaj ntawm wafer ncaj qha txiav txim siab qhov ua tau ntawm cov chip. Qhov no coj peb mus rau qhov kev txawj tseem ceeb ntawmsilicon carbide ntsuabmicropowder: tshuaj lom neeg kho tshuab polishing (CMP). Lao Zhang, tus kws ua haujlwm ntawm lub Hoobkas wafer, siv ib qho piv txwv zoo: "Nws zoo li muab wafer ib qho 'kev kho mob ntsej muag' - ua kom du thiab tsis sib xws yam tsis muaj khawb. Green silicon carbide micropowder zoo li cov khoom me me hauv cov khoom siv tu tawv nqaij zoo tshaj plaws - mos tab sis zoo." Tseeb tiag, hauv kev tsim cov chips, txawm tias ob peb feem kaum ntawm ib micron ntawm qhov tsis sib xws tuaj yeem ua rau luv lossis qhib Circuit Court.
Kev tswj cua sov yog ib qho kev sib tw tas mus li hauv kev lag luam semiconductor. Thaum kev sib koom ua ke ntawm cov chips nce ntxiv, kev tso cua sov tawm los ua qhov tseem ceeb dua.Ntsuab silicon carbide micropowdermuaj ib qho kev txawj tshwj xeeb hauv qhov no: ntxiv rau cov khoom siv thermally conductive ua rau kev cua sov ploj mus zoo dua. Ib tug kws ua haujlwm thermal ntawm lub tuam txhab chip paub zoo tau hais rau kuv tias, "Tam sim no peb siv cov hmoov silicon carbide ntsuab tshwj xeeb hauv peb cov thermal paste high-end, uas ua rau kev ua haujlwm cua sov ploj mus ntau dua 20%. Qhov no yog ib qho kev cawm siav hauv cov txheej txheem 5nm thiab 3nm."
Cov hmoov silicon carbide ntsuab tseem ceeb dua hauv kev tsim khoom siv semiconductor. Ntau yam khoom tseem ceeb hauv cov tshuab lithography thiab cov tshuab etching, uas tuaj yeem raug nqi kaum lab yuan, xav tau kev ua haujlwm siab heev. Piv txwv li, cov tshuab kho qhov muag ntawm cov tshuab lithography xav tau qhov tiaj tiaj iav siab heev, uas yuav tsum tau siv cov hmoov silicon carbide ntsuab raukev sib tsoo precisionIb tug tub rog qub uas muaj 20 xyoo ntawm kev paub dhau los hais tias, "Kev siv cov khoom no yog qhov nyuaj heev. Qhov loj me ntawm cov khoom me me, qhov concentration, thiab pH tus nqi txhua yam yuav tsum tau tswj kom meej; txawm tias qhov kev hloov pauv me me tuaj yeem cuam tshuam rau qhov tshwm sim kawg."
Nws tsim nyog sau tseg tias nrog rau kev nce ntawm cov ntaub ntawv semiconductor tiam thib peb, cov hmoov silicon carbide ntsuab tau pom ib daim ntawv thov tshiab. Cov khoom siv semiconductor raws li silicon carbide lawv tus kheej xav tau cov hmoov silicon carbide ntsuab rau kev sib tsoo thiab polishing thaum lub sijhawm ua tiav. Nws yog ib lub voj voog nthuav - siv silicon carbide los ua cov silicon carbide. Tus thawj coj kev tshaj lij ntawm lub tuam txhab khoom siv semiconductor tshiab luag nyav thiab hais tias, "Nws zoo li siv pob zeb diamond los txiav pob zeb diamond; tsuas yog cov ntaub ntawv zoo li tuaj yeem nkag siab ib leeg tiag tiag."
Cov hmoov silicon carbide ntsuab kuj tseem ua lub luag haujlwm tshwj xeeb hauv kev tswj xyuas zoo. Cov chaw tsim khoom semiconductor xav tau kev saib xyuas cov khoom siv tsis tu ncua, tshwj xeeb tshaj yog kev ntxuav cov kab conveyor thiab cov chaw ua haujlwm tshuaj. Vim tias cov hmoov silicon carbide ntsuab yog cov tshuaj lom neeg inert thiab tsis qhia cov pa phem tshiab, nws yog cov khoom siv nyiam rau cov txheej txheem ntxuav. Ib tug kws kho tshuab tau qhia tias, "Piv rau lwm cov khoom siv abrasives,hmoov silicon carbide ntsuabtsis tso cov hlau ions rau ntawm phab ntsa sab hauv ntawm cov khoom siv, uas yog qhov tseem ceeb rau kev tswj hwm ib puag ncig huv si hauv kev tsim cov chips.
Tau kawg, txhua yam khoom siv muaj chaw rau kev txhim kho. Cov teeb meem tam sim no uas ntsib nrog cov hmoov silicon carbide ntsuab feem ntau yog nyob rau hauv kev tswj tus nqi thiab kev sib xws zoo. Cov txheej txheem tsim khoom nyuaj thiab kev siv hluav taws xob ntau ua rau nws tus nqi siab. Ntxiv mus, kev sib xws ntawm cov pawg yog qhov kev txhawj xeeb tseem ceeb rau cov neeg siv. Txawm li cas los xij, ntau lub tuam txhab hauv tsev loj twb tau daws cov teeb meem no, maj mam txo qhov sib txawv nrog cov khoom xa tuaj los ntawm kev txhim kho cov txheej txheem tsim khoom thiab cov txheej txheem tswj xyuas zoo.
Saib mus tom ntej, thaum cov thev naus laus zis semiconductor hloov zuj zus mus rau cov txheej txheem me dua thiab qib siab dua ntawm kev koom ua ke, qhov kev thov rau cov hmoov silicon carbide ntsuab yuav txuas ntxiv mus loj hlob. Qhov no yog qhov tseeb tshwj xeeb hauv cov teb tshiab xws li cov chips txawj ntse, 5G kev sib txuas lus chips, thiab cov chips tsav tsheb tsis siv neeg, uas tso qhov kev thov siab dua rau kev ua tiav thiab kev ua haujlwm kub dissipation. Qhov no qhib ntau yam kev siv rau cov hmoov silicon carbide ntsuab.
Kuv nco qab ib tug kws tshaj lij hauv kev lag luam hais tias, "Kev lag luam semiconductor zoo li lub iceberg. Yam uas tib neeg pom tsuas yog tus tsim chip thiab kev tsim khoom loj saum npoo av xwb, thaum cov ntaub ntawv, cov txheej txheem, thiab cov khoom siv hauv qab npoo av yog lub hauv paus uas txhawb nqa tag nrho kev lag luam." Cov hmoov silicon carbide ntsuab yog ib qho tseem ceeb ntawm cov ntaub ntawv tseem ceeb no. Nws yuav tsis zoo nkauj npaum li lub tshuab lithography, tab sis nws yog cov ntaub ntawv "tsis pom tseeb" no uas txhawb nqa kev txhim kho ntawm tag nrho kev lag luam semiconductor.
Lub sijhawm tom ntej koj siv lub xov tooj ntse lossis tsav lub tsheb ntse, tej zaum xav txog tias tom qab cov khoom siv thev naus laus zis siab no yog qhov kev pab txhawb los ntawm cov khoom siv "tsis tseem ceeb" xws li cov hmoov silicon carbide ntsuab. Tom qab tag nrho, kev nce qib ntawm txhua qhov kev lag luam yog qhov tsis sib cais los ntawm cov "heroes tom qab qhov xwm txheej" uas ntsiag to, mob siab rau.
