Cov qhov tsis zoo ntawm granite hauv kev lag luam semiconductor yog dab tsi?

Nyob rau hauv kev lag luam semiconductor raws li qhov yuav tsum tau ua kom raug thiab muaj kev ntseeg siab, txawm hais tias granite yog ib qho ntawm cov ntaub ntawv tseem ceeb, nws cov khoom kuj coj qee qhov kev txwv. Cov hauv qab no yog nws cov teeb meem tseem ceeb thiab cov teeb meem hauv kev siv:
Ua ntej, cov khoom siv yog qhov brittle heev thiab nyuaj rau ua tiav
Kev Pheej Hmoo ntawm kev tawg: Granite yog ib lub pob zeb ntuj tsim uas muaj cov kab nrib pleb me me thiab cov ciam teb ntawm cov khoom siv hauv av, thiab nws yog cov khoom siv tawg yooj yim. Hauv kev siv tshuab ua kom raug (xws li kev sib tsoo nanoscale thiab kev ua cov khoom siv nkhaus nyuaj), yog tias lub zog tsis sib npaug lossis cov txheej txheem ua tsis tsim nyog, teeb meem xws li chipping thiab microcrack propagation yuav tshwm sim, ua rau cov khoom siv pov tseg.

Kev ua haujlwm tsis zoo: Txhawm rau kom tsis txhob muaj kev tawg yooj yim, cov txheej txheem tshwj xeeb xws li kev sib tsoo ceev qis nrog cov log sib tsoo pob zeb diamond thiab kev sib tsoo magnetorheological yog qhov yuav tsum tau ua. Lub voj voog ua haujlwm ntev dua li ntawm 30% txog 50% dua li ntawm cov khoom siv hlau, thiab tus nqi peev txheej ntawm cov khoom siv siab (piv txwv li, tus nqi ntawm tsib-axis txuas machining center tshaj 10 lab yuan).
Cov kev txwv ntawm cov qauv nyuaj: Nws nyuaj rau tsim cov qauv hollow los ntawm kev casting, forging thiab lwm yam txheej txheem. Nws feem ntau yog siv rau hauv cov duab geometric yooj yim xws li phaj thiab lub hauv paus, thiab nws daim ntawv thov yog txwv rau cov khoom siv uas xav tau kev txhawb nqa tsis sib xws lossis kev koom ua ke ntawm cov kav dej sab hauv.
Qhov thib ob, qhov ceev ceev ua rau muaj kev thauj khoom hnyav rau ntawm cov khoom siv
Nyuaj rau kev tuav thiab teeb tsa: Qhov ceev ntawm granite yog kwv yees li 2.6-3.0 g / cm³, thiab nws qhov hnyav yog 1.5-2 npaug ntawm cov hlau cam khwb cia hauv tib lub ntim. Piv txwv li, qhov hnyav ntawm lub hauv paus granite rau lub tshuab photolithography tuaj yeem ncav cuag 5 txog 10 tons, xav tau cov khoom siv tsa tshwj xeeb thiab cov hauv paus tiv thaiv kev co, uas ua rau tus nqi ntawm kev tsim kho Hoobkas thiab kev xa khoom siv nce ntxiv.
Kev teb qeeb ntawm lub zog: Kev inertia siab txwv qhov kev nrawm ntawm cov khoom txav mus los ntawm cov khoom siv (xws li cov neeg hlau hloov wafer). Hauv cov xwm txheej uas xav tau pib thiab nres sai (xws li cov khoom siv tshuaj xyuas ceev ceev), nws yuav cuam tshuam rau lub suab tsim khoom thiab txo qhov ua haujlwm tau zoo.
Qhov thib peb, tus nqi kho thiab rov ua dua yog siab
Cov qhov tsis zoo yog qhov nyuaj kho: Yog tias qhov chaw puas tsuaj lossis kev sib tsoo tshwm sim thaum lub sijhawm siv, nws yuav tsum tau xa rov qab mus rau lub Hoobkas kom kho los ntawm cov khoom siv sib tsoo tshaj lij, uas tsis tuaj yeem ua tiav sai sai ntawm qhov chaw. Qhov sib txawv, cov khoom siv hlau tuaj yeem kho tau tam sim ntawd los ntawm cov txheej txheem xws li kev vuam chaw thiab laser cladding, ua rau lub sijhawm tsis ua haujlwm luv dua.
Lub voj voog rov ua dua ntawm kev tsim qauv yog ntev: Qhov sib txawv ntawm cov leeg granite ntuj yuav ua rau muaj kev hloov pauv me ntsis hauv cov khoom siv (xws li cov coefficient thermal expansion thiab damping ratio) ntawm cov pawg sib txawv. Yog tias cov qauv tsim khoom hloov pauv, cov khoom siv yuav tsum tau rov ua dua, thiab lub voj voog tshawb fawb thiab kev txhim kho yog ntev heev.
Iv. Cov Kev Pab Cuam Tsawg thiab Cov Teeb Meem Ib puag ncig
Pob zeb ntuj tsis rov ua dua tshiab: Cov pob zeb granite zoo (xws li "Jinan Green" thiab "Sesame Black" siv rau hauv semiconductors) vam khom cov leeg tshwj xeeb, muaj cov khoom khaws cia tsawg thiab nws cov kev khawb av raug txwv los ntawm cov cai tiv thaiv ib puag ncig. Nrog rau kev nthuav dav ntawm kev lag luam semiconductor, tej zaum yuav muaj kev pheej hmoo ntawm kev muab khoom siv raw tsis ruaj khov.
Cov teeb meem ua qias tuaj: Thaum lub sijhawm txiav thiab sib tsoo, yuav muaj ntau cov hmoov av granite (uas muaj silicon dioxide) tsim tawm. Yog tias tsis siv kom zoo, nws yuav ua rau muaj silicosis. Ntxiv mus, cov dej khib nyiab yuav tsum tau kho los ntawm kev tso dej tawm ua ntej tso tawm, ua rau muaj kev nqis peev tiv thaiv ib puag ncig ntau ntxiv.
Tsib. Tsis sib haum xeeb txaus nrog cov txheej txheem tshiab
Cov kev txwv ntawm qhov chaw nqus tsev: Qee cov txheej txheem semiconductor (xws li txheej nqus tsev thiab electron beam lithography) yuav tsum tau tswj hwm lub xeev nqus tsev siab hauv cov khoom siv. Txawm li cas los xij, cov qhov me me ntawm qhov chaw ntawm granite tuaj yeem nqus cov roj molecules, uas maj mam tso tawm thiab cuam tshuam rau qhov ruaj khov ntawm qib nqus tsev. Yog li ntawd, kev kho mob ntxiv ntawm qhov chaw ntom ntom (xws li resin impregnation) yog qhov tsim nyog.
Cov teeb meem sib xws ntawm electromagnetic: Granite yog cov khoom siv rwb thaiv tsev. Hauv cov xwm txheej uas xav tau kev tso tawm hluav taws xob zoo li qub lossis kev tiv thaiv hluav taws xob (xws li wafer electrostatic adsorption platforms), cov txheej txheem hlau lossis cov yeeb yaj kiab conductive yuav tsum tau sib xyaw, ua rau muaj kev nyuaj thiab tus nqi ntau ntxiv.
Txoj kev teb rau kev lag luam
Txawm hais tias muaj qhov tsis zoo saum toj no, kev lag luam semiconductor tau ua ib feem ntawm cov tsis zoo ntawm granite los ntawm kev tsim kho tshiab:

Kev tsim qauv sib xyaw ua ke: Nws siv kev sib xyaw ua ke ntawm "granite base + metal frame", coj mus rau hauv tus account ob qho tib si rigidity thiab lub teeb (piv txwv li, ib qho chaw tsim khoom siv photolithography tshuab embeds ib qho aluminium alloy honeycomb qauv hauv granite base, txo qhov hnyav los ntawm 40%).
Cov khoom siv hluavtaws cuav lwm txoj hauv kev: Tsim cov khoom sib xyaw ua ke ntawm cov khoom siv ceramic matrix (xws li silicon carbide ceramics) thiab cov pob zeb cuav ua los ntawm epoxy resin los ua qauv qhia txog kev ruaj khov ntawm thermal thiab kev tiv thaiv kev co ntawm granite, thaum txhim kho kev ua haujlwm yooj yim.
Kev siv tshuab ua haujlwm ntse: Los ntawm kev qhia txog AI algorithms los ua kom zoo dua txoj kev ua haujlwm, kev sim ua kom muaj kev ntxhov siab los kwv yees qhov kev pheej hmoo ntawm kev tawg, thiab kev sib koom ua ke ntawm kev tshawb pom hauv online los kho cov kev teeb tsa hauv lub sijhawm tiag tiag, tus nqi ua cov khoom seem tau raug txo qis los ntawm 5% mus rau qis dua 1%.
Kev Txheeb Xyuas
Qhov tsis zoo ntawm granite hauv kev lag luam semiconductor feem ntau yog los ntawm qhov kev ua si ntawm nws cov khoom siv ntuj thiab kev xav tau kev lag luam. Nrog rau kev nce qib ntawm thev naus laus zis thiab kev tsim cov ntaub ntawv lwm yam, nws cov xwm txheej siv yuav maj mam txo qis mus rau "cov khoom siv tseem ceeb uas tsis tuaj yeem hloov pauv tau" (xws li cov kev taw qhia hydrostatic rau cov tshuab photolithography thiab cov platform ntsuas ultra-precision), thaum maj mam muab txoj hauv kev rau cov ntaub ntawv engineering yooj ywm dua hauv cov khoom tsis tseem ceeb. Yav tom ntej, yuav ua li cas kom sib npaug kev ua tau zoo, tus nqi thiab kev ruaj khov yuav yog ib qho kev kawm uas kev lag luam txuas ntxiv tshawb nrhiav.
