Hauv 2018, lub ntiaj teb hluav taws xob hluav taws xob ua lag luam rau kev sib koom ua ke tau mus txog US $ 4.512 billion, ib xyoos ib zaug nce ntawm 16%. Kev loj hlob siab ntawm kev lag luam hluav taws xob tshwj xeeb roj rau cov khoom siv hluav taws xob thiab cov lag luam loj loj tau ua kom cov kev hloov pauv hauv tsev ntawm hluav taws xob tshwj xeeb roj!
electron gas yog dab tsi?
Cov roj hluav taws xob hais txog cov khoom siv hluav taws xob siv hauv kev tsim cov khoom siv hluav taws xob, cov vaj huam sib luag tiaj tus, lub teeb-emitting diodes, lub hnub ci hlwb thiab lwm yam khoom siv hluav taws xob, thiab tau siv dav hauv kev tu, etching, zaj duab xis tsim, doping thiab lwm yam txheej txheem. Cov chaw siv hluav taws xob tseem ceeb suav nrog kev lag luam hluav taws xob, hluav taws xob hnub ci, kev sib txuas lus ntawm tes, tsheb navigation thiab tsheb audio thiab video systems, aerospace, tub rog kev lag luam thiab ntau lwm yam.
Cov roj hluav taws xob tshwj xeeb tuaj yeem muab faib ua xya pawg raws li nws cov tshuaj muaj pes tsawg leeg: silicon, arsenic, phosphorus, boron, hlau hydride, halide thiab hlau alkoxide. Raws li cov txheej txheem sib txawv hauv kev sib xyaw ua ke, nws tuaj yeem muab faib ua cov pa roj doping, epitaxy gas, ion implantation gas, lub teeb-emitting diode roj, etching gas, tshuaj vapor deposition roj thiab tshuav roj. Muaj ntau tshaj 110 chav tsev tshwj xeeb gases siv nyob rau hauv kev lag luam semiconductor, uas ntau tshaj 30 feem ntau siv.
Feem ntau, kev lag luam tsim khoom semiconductor faib cov pa roj rau ob hom: cov pa roj thiab cov roj tshwj xeeb. Ntawm lawv, cov roj siv feem ntau yog hais txog cov khoom siv hauv nruab nrab thiab siv cov roj ntau, xws li N2, H2, O2, Ar, Nws, thiab lwm yam. Cov roj tshwj xeeb yog hais txog qee cov roj siv hluav taws xob siv hauv cov txheej txheem ntawm cov khoom siv semiconductor, xws li Extension, ion txhaj, sib tov, ntxuav, thiab daim npog qhov ncauj, uas yog qhov peb tam sim no hu ua hluav taws xob tshwj xeeb roj, xws li high-purity SiH4, PH3, AsH3, B2H6, N2O, NH3, SF6, NF3, CF4, BCl3, BF3, HCl, Cl2, thiab lwm yam.
Nyob rau hauv tag nrho cov txheej txheem ntawm kev lag luam semiconductor, los ntawm kev loj hlob ntawm nti mus rau lub ntim khoom zaum kawg, yuav luag txhua qhov txuas yog sib cais los ntawm cov roj hluav taws xob tshwj xeeb, thiab cov roj siv ntau yam thiab cov kev xav tau zoo, yog li cov roj hluav taws xob muaj cov khoom siv semiconductor. "Foos".
Nyob rau hauv xyoo tas los no, Tuam Tshoj cov khoom siv hluav taws xob loj xws li cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob tau nce ntxiv hauv kev tsim khoom tshiab, thiab muaj kev xav tau zoo rau kev hloov pauv ntawm cov khoom siv hluav taws xob. Txoj hauj lwm ntawm cov roj hluav taws xob hauv kev lag luam semiconductor tau dhau los ua qhov tseem ceeb. Kev lag luam hluav taws xob hauv tsev yuav ua rau muaj kev loj hlob sai.
Cov roj hluav taws xob tshwj xeeb muaj cov kev xav tau siab heev rau purity, vim hais tias yog tias qhov purity tsis yog raws li qhov yuav tsum tau ua, cov pab pawg impurity xws li dej vapor thiab oxygen hauv cov pa hluav taws xob tshwj xeeb yuav yooj yim tsim oxide zaj duab xis rau ntawm qhov chaw ntawm lub semiconductor, uas cuam tshuam rau cov khoom siv hluav taws xob. kev pab cuam lub neej ntawm cov khoom siv hluav taws xob, thiab cov roj hluav taws xob tshwj xeeb muaj cov khoom ntawm impurities tuaj yeem ua rau semiconductor luv circuits thiab Circuit Court puas. Nws tuaj yeem hais tias kev txhim kho ntawm purity plays lub luag haujlwm tseem ceeb hauv kev tawm los thiab kev ua haujlwm ntawm cov khoom siv hluav taws xob.
Nrog rau kev txhim kho txuas ntxiv ntawm kev lag luam semiconductor, cov txheej txheem tsim cov nti txuas ntxiv txhim kho, thiab tam sim no nws tau mus txog 5nm, uas tab tom yuav mus txog qhov txwv ntawm Moore Txoj Cai, uas yog sib npaug rau ib-ntu ntawm txoj kab uas hla ntawm tib neeg cov plaub hau ( 0.1 hli). Yog li ntawd, qhov no kuj tso siab rau cov kev xav tau siab dua ntawm purity ntawm hluav taws xob tshwj xeeb roj uas tsim los ntawm semiconductors.
