(4) Liquid Phase Epitaxy (LPE)
Lub hauv paus ntsiab lus: Hauv cov kua hlau ua kua, SiC raw khoom epitaxial loj hlob ntawm substrate.
Cov yam ntxwv tseem ceeb:
Kev loj hlob kub yog qis (1000-1500 ° C).
Kev loj hlob sai, haum rau kev loj hlob ntawm zaj duab xis.
Crystal zoo yog siab, tab sis lub thickness yog txwv.
Daim ntawv thov: Feem ntau yog siv rau epitaxial kev loj hlob ntawm SiC films, xws li sensors thiab optoelectronic li.
Lub ntsiab daim ntawv thov txoj kev ntawm silicon carbide siv lead ua rauv
SiC siv lead ua rauv yog cov khoom siv tseem ceeb rau kev npaj sic siv lead ua, thiab nws txoj hauv kev siv tseem ceeb suav nrog:
Cov khoom siv hluav taws xob semiconductor: Siv los loj hlob zoo 4H-SiC thiab 6H-SiC crystals li substrate cov ntaub ntawv rau cov khoom siv fais fab (xws li MOSFETs, diodes).
Daim ntawv thov: hluav taws xob tsheb, photovoltaic inverters, muaj hluav taws xob khoom siv, thiab lwm yam.
Rf ntaus ntawv tsim: Siv los loj hlob tsis zoo SiC crystals li substrates rau RF cov khoom siv kom tau raws li qhov xav tau ntawm 5G kev sib txuas lus, radar thiab satellite kev sib txuas lus.
Optoelectronic device manufacturing: Siv los loj hlob zoo SiC crystals li substrate cov ntaub ntawv rau leds, ultraviolet detectors thiab lasers.
Kev tshawb fawb tshawb fawb thiab kev tsim khoom me me: rau kev tshawb fawb hauv chav kuaj thiab cov khoom siv tshiab tsim los txhawb kev tsim kho tshiab thiab kev ua kom zoo ntawm SiC siv lead ua kev loj hlob technology.
Kev tsim cov cuab yeej kub kub: Siv los loj hlob kub resistant SiC crystals raws li cov khoom siv rau aerospace thiab kub sensors.
SiC cov khoom siv hluav taws xob thiab cov kev pabcuam muab los ntawm lub tuam txhab
