Hauv kev lag luam ntawm cov ntaub ntawv tshiab, muaj ib yam khoom tshwj xeeb heev, hu ua CVD SiC. Qhov no yog lub npe luv rau cov tshuaj lom neeg vapor deposition silicon carbide. Nws muaj qhov tseem ceeb hauv ntau yam lag luam sib txawv thiab ua rau peb xav txog cov khoom siv hluav taws xob thiab lwm yam khoom muaj zog.
CVD SiC muaj kev siv dav. Nws muaj cov yam ntxwv zoo kawg nkaus suav nrog lub peev xwm zoo heev rau kev coj cua sov, tsis hloov pauv ntau thaum raug cua sov thiab, muaj zog heev. Cov yam ntxwv no ua rau nws zoo heev rau cov khoom uas peb ua kom kav ntev thiab uas tau tsim los ua haujlwm. Semixlab txheej txheem CVD SiC kuj tsis yooj yim rau xeb thiab tuaj yeem tiv taus qhov kub siab, uas ua rau nws haum rau cov chaw ib puag ncig hnyav.
Kev siv hluav taws xob yog lwm qhov chaw loj uas xav tau SiC. Nws tso cai rau cov khoom siv kom tso cua sov sai dua, yog li nws twb yog cov khoom siv zoo tshaj plaws rau cov khoom siv hluav taws xob xws li inverters thiab cov khoom siv fais fab. Nws muaj lub zog tawg siab thiab yog tus coj hluav taws xob zoo, yog li nws ua haujlwm zoo hauv cov khoom siv xws li diodes thiab transistors. Vim tias peb xav tau cov khoom siv hluav taws xob sai dua, ua haujlwm tau zoo dua, CVD SiC tau npaj los txhawb nqa thev naus laus zis thaum nws nthuav dav.
Peb xav tau cov khoom siv hluav taws xob me dua, sai dua, thiab txhim khu kev qha dua thaum thev naus laus zis zoo zuj zus. Semixlab cov khoom siv CVD SiC yog qhov zoo rau cov khoom siv hluav taws xob tiam tom ntej vim nws ua tau zoo hauv hluav taws xob thiab ruaj khov. Nws muaj qhov bandgap loj, uas ua rau nws txhawb nqa cov hluav taws xob siab dua thiab kub dua rau kev ua tau zoo dua thiab kev ua haujlwm zoo dua. Nrog kev tshawb nrhiav ntxiv, CVD SiC yuav luag ua lub luag haujlwm tseem ceeb hauv cov khoom siv hluav taws xob yav tom ntej.
CVD SiC kuj tseem siv tau ua ib txheej txheej rau ntau yam khoom siv thoob plaws hauv kev lag luam. Cov txheej txheej zoo li no muab ib txheej tiv thaiv uas tuaj yeem ua rau cov khoom siv kav ntev dua thiab ua haujlwm tau zoo dua, zoo li cov cuab yeej txiav thiab cov khoom hloov pauv cua sov. Nrog CVD SiC txheej txheej, cov tuam txhab tuaj yeem ua pa tshiab rau hauv lawv cov khoom siv thiab zam kev kho kim.
CVD SiC yog ib yam khoom muaj nqis heev rau kev siv rau hauv aerospace thiab automotive. Nws lub teeb, muaj zog thiab tawv nyob rau hauv qhov xwm txheej nyuaj, yog li nws yog ib yam khoom zoo tagnrho rau cov dav hlau thiab tsheb. Ua ib qho khoom siv dav hlau rau cov discs nres, Semixlab txheej CVD SiC ua rau muaj kev daws teeb meem tshiab uas hloov pauv qhov peb ua tau hauv cov chaw no.
