Hauv cov txheej txheem tsim khoom semiconductor, ntau cov ntaub ntawv tseem ceeb thiab cov khoom sib xyaw txiav txim siab qhov ruaj khov ntawm cov txheej txheem thiab cov khoom tsim tawm. Txawm hais tias cov khoom siv semiconductor graphite tsis tau txais kev saib xyuas ntau npaum li wafers lossis cov hom phiaj, lawv ib txwm ua lub luag haujlwm tseem ceeb hauv kev ua cov txheej txheem kub siab, kev loj hlob epitaxial, annealing, thiab kev tsim khoom semiconductor sib xyaw.
Hais yooj yim xwb,Cov khoom siv semiconductor graphiteyog cov khoom siv ua haujlwm siv rau hauv cov khoom siv ua haujlwm kub siab, feem ntau yog lub luag haujlwm rau cov haujlwm xws li kev thauj khoom, kev txhawb nqa, kev teeb tsa, thiab kev hloov pauv cua sov. Lawv feem ntau yog ua los ntawm graphite purity siab, thiab cov txheej txheem saum npoo xws li SiC tuaj yeem siv raws li cov txheej txheem xav tau los txhim kho kev tiv taus kub siab, kev tiv taus oxidation, thiab kev tiv taus corrosion.
Graphite siv dav hauv kev lag luam semiconductor vim muaj ntau yam zoo ntawm cov khoom siv. Ua ntej, graphite muaj kev ruaj khov zoo heev thaum kub siab thiab tuaj yeem tiv taus cov xwm txheej ua haujlwm kub hnyav. Qhov thib ob, nws cov thermal conductivity thiab thermal shock tsis kam pab tswj kev faib tawm kub sib xws. Tsis tas li ntawd, graphite muaj kev siv tshuab zoo, ua rau nws ua tau raws li qhov xav tau ntawm cov qauv nyuaj thiab cov kev xav tau siab.
Hauv kev siv ua haujlwm, cov khoom siv graphite feem ntau siv rau hauv epitaxy, diffusion, annealing, thiab cov txheej txheem sib xyaw semiconductor. Tshwj xeeb tshaj yog hauv kev tsim cov semiconductors dav dav xws li SiC thiab GaN, qhov twg cov txheej txheem kub siab dua thiab ib puag ncig nyuaj dua, qhov xav tau siab dua rau kev huv, kev ruaj khov ntawm cov qauv, thiab kev kho qhov chaw ntawm cov khoom siv graphite.
Tsis tas li ntawm cov khoom siv uas muaj nyob hauv, qhov kev ua haujlwm raug thiab kev sib xws ntawm cov khoom siv graphite kuj tseem ceeb ib yam nkaus. Rau cov khoom siv semiconductor, cov khoom siv tsis yog tsuas yog ua cov khoom txhawb nqa xwb tab sis kuj cuam tshuam ncaj qha rau qhov sib npaug ntawm kev faib cua sov thiab kev ruaj khov ntawm qhov chaw thaum lub sijhawm tsim khoom. Kev tswj qhov ntev tsis txaus lossis kev kho qhov chaw tsis zoo feem ntau ua rau cov txheej txheem rov ua dua thiab tej zaum yuav ua rau muaj kev sib kis ntawm cov khoom me me thiab cov nqi kho kom zoo dua.
Thaum kev lag luam semiconductor txuas ntxiv mus rau cov txheej txheem nyuaj dua, kev xav tau ntawm kev ua lag luam rau cov khoom siv graphite kuj nce siab. Tshaj li qhov huv siab thiab qhov ceev siab, cov khoom me me, cov pa phem tsawg, qhov sib xws ntawm qhov loj me, thiab lub neej ua haujlwm ntev yog cov qauv tseem ceeb rau kev ntsuam xyuas qhov zoo ntawm cov khoom. Qhov no qhia tau hais tias cov khoom siv graphite tsis yog cov khoom siv pabcuam xwb tab sis tau dhau los ua cov khoom tseem ceeb uas cuam tshuam ncaj qha rau kev ua haujlwm ntawm cov txheej txheem.
Saib ntawm cov qauv kev lag luam, cov khoom siv graphite ua tau zoo yav tom ntej yuav muab qhov tseem ceeb dua rau kev sib koom ua ke ntawm kev hloov kho cov khoom siv thiab cov thev naus laus zis tiv thaiv nto. Tshwj xeeb tshaj yog tiv thaiv keeb kwm yav dhau los ntawm kev nce qib sai hauv cov semiconductors dav dav, cov txheej txheem kub siab, thiab cov txheej txheem thermal precision, cov khoom siv graphite nrog kev huv dua, kev ruaj khov dua, thiab kev ua haujlwm sib xws dua yuav ua lub luag haujlwm tseem ceeb hauv cov saw hlau semiconductor.
Zuag qhia tag nrho,Cov khoom siv semiconductor graphiteua lub luag haujlwm tseem ceeb hauv kev tsim khoom semiconductor. Yav tom ntej, thaum qhov kev thov rau cov semiconductors dav dav thiab cov txheej txheem kub siab txuas ntxiv mus, cov khoom siv graphite ua tau zoo kuj tseem yuav pom cov ntawv thov dav dua.
