1.Yuav ua li cas thiaj ua tau ib qho siv lead ua wafer
Thawj kauj ruam yog metallurgical purification, uas koom nrog ntxiv cov pa roj carbon monoxide thiab hloov silicon oxide rau silicon ntawm 98% lossis ntau dua purity siv redox.Cov hlau feem ntau, xws li hlau lossis tooj liab, yog ua kom zoo li no kom tau txais cov hlau ntshiab txaus.Txawm li cas los xij, 98% tseem tsis txaus rau kev tsim cov chips thiab xav tau kev txhim kho ntxiv.Yog li ntawd, cov txheej txheem Siemens yuav raug siv rau kev ua kom huv ntxiv kom tau txais lub siab purity polysilicon xav tau rau cov txheej txheem semiconductor.
Cov kauj ruam tom ntej yog rub cov crystals.Ua ntej, cov high-purity polysilicon tau ua ntej yog yaj los ua kua silicon.Tom qab ntawd, ib qho siv lead ua ntawm cov noob silicon raug coj mus rau hauv kev sib cuag nrog cov kua nto thiab maj mam rub mus rau sab saud thaum tig.Yog vim li cas rau qhov xav tau ib lub noob siv lead ua yog tias, ib yam li ib tus neeg nyob hauv kab, cov silicon atoms yuav tsum tau muab tso rau hauv kom cov neeg tuaj tom qab lawv paub yuav ua li cas rau kab kom raug.Thaum kawg, thaum cov silicon atoms tau tawm ntawm cov kua saum npoo thiab solidified, cov txheej txheem zoo tib yam siv lead ua silicon kem tiav.
Tab sis dab tsi yog 8 "thiab 12" sawv cev?Nws yog xa mus rau txoj kab uas hla ntawm tus ncej peb tsim, qhov uas zoo li lub xaum xaum tom qab qhov chaw tau kho thiab hlais rau hauv nyias wafers.Dab tsi yog qhov nyuaj ntawm kev ua cov wafers loj?Raws li tau hais ua ntej, cov txheej txheem ntawm kev ua wafers zoo li ua marshmallows, spinning thiab shaping lawv thaum koj mus.Txhua tus neeg uas tau ua marshmallows ua ntej yuav paub tias nws yog ib qho nyuaj heev los ua kom loj, khoom marshmallows, thiab tib yam mus rau lub wafer rub txheej txheem, qhov twg qhov ceev ntawm kev sib hloov thiab kub tswj muaj feem xyuam rau qhov zoo ntawm wafer.Yog li ntawd, qhov loj me me, qhov siab dua qhov xav tau ntawm qhov kub thiab txias, ua rau nws nyuaj rau tsim cov khoom zoo 12 "wafer dua li 8" wafer.
Txhawm rau tsim cov wafer, lub pob zeb diamond cutter yog siv los txiav cov wafer kab rov tav rau hauv wafers, uas tom qab ntawd polished los ua cov wafers xav tau rau kev tsim cov chips.Cov kauj ruam tom ntej yog stacking tsev los yog chip manufacturing.Yuav ua li cas koj ua ib tug chip?
2.Tom qab tau qhia txog dab tsi silicon wafers yog, nws kuj tseem pom tseeb tias kev tsim IC chips zoo li tsim lub tsev nrog Lego blocks, los ntawm stacking lawv txheej rau txheej los tsim cov duab koj xav tau.Txawm li cas los xij, muaj ob peb kauj ruam los tsim lub tsev, thiab tib yam mus rau kev tsim IC.Dab tsi yog cov kauj ruam koom nrog hauv kev tsim IC?Cov lus hauv qab no piav qhia txog cov txheej txheem ntawm IC chip manufacturing.
Ua ntej peb pib, peb yuav tsum to taub tias IC nti yog dab tsi - IC, los yog Integrated Circuit Court, raws li nws hu ua, yog ib pawg ntawm tsim circuits uas muab tso ua ke nyob rau hauv ib tug stacked zam.Los ntawm kev ua qhov no, peb tuaj yeem txo cov cheeb tsam uas xav tau los txuas cov circuits.Daim duab hauv qab no qhia txog daim duab 3D ntawm IC Circuit Court, uas tuaj yeem pom tau los ua qauv zoo li cov kab teeb thiab kab ntawm lub tsev, muab tso rau ntawm ib sab, uas yog vim li cas IC kev tsim khoom zoo li lub tsev.
Los ntawm 3D ntu ntawm IC nti qhia saum toj no, qhov tsaus xiav hauv qab yog wafer qhia hauv ntu dhau los.Cov xim liab thiab lub ntiaj teb-xim yog qhov chaw ua IC.
Ua ntej tshaj plaws, qhov liab tuaj yeem muab piv rau hauv av pem teb ntawm lub tsev siab.Qhov chaw tos txais hauv pem teb yog lub rooj vag mus rau lub tsev, qhov twg nkag mus tau, thiab feem ntau ua haujlwm zoo dua ntawm kev tswj cov tsheb.Yog li ntawd nws yog qhov nyuaj los tsim dua lwm cov plag tsev thiab yuav tsum tau ua ntau kauj ruam.Hauv IC Circuit Court, chav tsev no yog txheej txheej logic rooj vag, uas yog qhov tseem ceeb tshaj plaws ntawm tag nrho IC, sib txuas ntau lub rooj vag logic los tsim kom muaj kev ua haujlwm siab IC nti.
Qhov daj yog zoo li ib txwm hauv pem teb.Piv rau hauv pem teb, nws tsis yog qhov nyuaj heev thiab tsis hloov ntau ntawm hauv pem teb mus rau hauv pem teb.Lub hom phiaj ntawm hauv pem teb no yog los txuas cov logic rooj vag hauv seem liab ua ke.Yog vim li cas rau qhov xav tau ntau txheej yog vim muaj ntau lub voj voog sib txuas ua ke thiab yog tias ib txheej tsis tuaj yeem ua kom haum rau txhua lub voj voog, ob peb txheej yuav tsum tau muab tso ua ke kom ua tiav lub hom phiaj no.Nyob rau hauv cov ntaub ntawv no, cov txheej txheem sib txawv yog txuas nrog nce thiab nqis kom tau raws li cov kev xav tau ntawm kev xaim.
