SEMICONDUCTOR
SEMICONDUCTOR yog dab tsi?
Cov khoom siv hluav taws xob semiconductor yog cov khoom siv hluav taws xob uas siv hluav taws xob ua hluav taws xob tab sis muaj cov yam ntxwv uas nyob nruab nrab ntawm tus neeg xyuas pib, piv txwv li tooj liab, thiab cov insulator, xws li iav. Cov khoom siv no siv hluav taws xob ua hluav taws xob hauv cov khoom hauv lub xeev uas tsis yog nyob rau hauv lub xeev gaseous lossis thermionic emission nyob rau hauv lub tshuab nqus tsev, thiab lawv tau hloov lub tshuab nqus tsev hauv cov ntawv thov niaj hnub no.
Feem ntau siv cov semiconductors yog nyob rau hauv integrated circuit chips. Peb cov cuab yeej siv niaj hnub no, suav nrog cov xov tooj ntawm tes thiab ntsiav tshuaj, tuaj yeem muaj ntau lab tus me me semiconductors koom nrog ib qho chips txhua qhov sib cuam tshuam ntawm ib qho semiconductor wafer.
Lub conductivity ntawm ib tug semiconductor yuav manipulated nyob rau hauv ntau txoj kev, xws li los ntawm kev qhia ib tug hluav taws xob los yog magnetic teb, los ntawm nthuav nws mus rau lub teeb los yog kub, los yog vim lub mechanical deformation ntawm ib tug doped monocrystalline silicon daim phiaj. Txawm hais tias cov lus piav qhia yog cov ncauj lus kom ntxaws, kev tswj hwm ntawm semiconductors yog dab tsi tau ua rau peb lub kiv puag ncig digital tam sim no ua tau.
YUAV UA LI CAS ALUMINIUM siv hauv SEMICONDUCTORS?
Aluminium muaj ntau yam khoom uas ua rau nws yog thawj qhov kev xaiv rau siv hauv semiconductors thiab microchips. Piv txwv li, txhuas muaj superior adhesion rau silicon dioxide, ib feem tseem ceeb ntawm semiconductors (qhov no yog qhov uas Silicon Valley tau txais nws lub npe). Nws yog cov khoom siv hluav taws xob, uas yog tias nws muaj hluav taws xob tsawg thiab ua rau kev sib cuag zoo nrog cov hlua khi, yog lwm qhov txiaj ntsig ntawm txhuas. Kuj tseem ceeb yog tias nws yooj yim rau kev tsim cov txhuas hauv cov txheej txheem qhuav etch, ib kauj ruam tseem ceeb hauv kev ua cov khoom siv semiconductors. Thaum lwm yam hlau, xws li tooj liab thiab nyiaj, muaj kev tiv thaiv zoo dua corrosion thiab hluav taws xob toughness, lawv kuj tseem kim dua txhuas.
Ib qho ntawm cov kev siv ntau tshaj plaws rau txhuas hauv kev tsim cov semiconductors yog nyob rau hauv cov txheej txheem ntawm sputtering technology. Cov txheej nyias nyias ntawm nano thicknesses ntawm high-purity hlau thiab silicon nyob rau hauv microprocessor wafers yog ua tiav los ntawm ib tug txheej txheem ntawm lub cev vapor deposition hu ua sputtering. Cov khoom raug tshem tawm los ntawm lub hom phiaj thiab tso rau ntawm lub substrate txheej ntawm silicon nyob rau hauv lub tshuab nqus tsev chamber uas tau ntim nrog roj los pab txhawb txoj kev; feem ntau yog inert gas xws li argon.
Cov ntawv thaub qab rau cov hom phiaj no yog ua los ntawm txhuas nrog cov ntaub ntawv purity siab rau kev tso nyiaj, xws li tantalum, tooj liab, titanium, tungsten lossis 99.9999% ntshiab txhuas, sib txuas rau lawv qhov chaw. Photoelectric los yog tshuaj etching ntawm lub substrate tus conductive nto tsim lub microscopic circuitry qauv siv nyob rau hauv lub semiconductor txoj hauj lwm.
Qhov feem ntau aluminium alloy hauv semiconductor ua yog 6061. Kom ntseeg tau tias qhov kev ua tau zoo tshaj plaws ntawm cov hlau, feem ntau cov txheej txheem tiv thaiv anodized yuav raug siv rau saum npoo ntawm cov hlau, uas yuav txhawb kev tiv thaiv corrosion.
Vim tias lawv yog cov khoom siv zoo li no, corrosion thiab lwm yam teeb meem yuav tsum tau saib xyuas kom zoo. Ntau yam tau pom los ua kom muaj kev cuam tshuam rau hauv cov khoom siv semiconductor, piv txwv li ntim rau hauv cov yas.
