4H-N Dia205mm SiC mbewu yochokera ku China P ndi D kalasi ya Monocrystaline

Njira ya PVT (Physical Vapor Transport) ndi njira yodziwika bwino yomwe imagwiritsidwa ntchito kukulitsa silicon carbide single crystals. Pakukula kwa PVT, silicon carbide single crystal material imayikidwa ndi evaporation yakuthupi ndikuyendetsa pamakristali ambewu ya silicon carbide, kotero kuti makristalo atsopano a silicon carbide amakula motsatira kapangidwe ka makristasi a mbewu.

Mu njira ya PVT, kristalo ya silicon carbide seed imakhala ndi gawo lofunikira monga poyambira ndi template yakukulira, kukhudza mtundu ndi kapangidwe ka kristalo imodzi yomaliza. Panthawi ya kukula kwa PVT, poyang'anira magawo monga kutentha, kupanikizika ndi gasi-gawo, kukula kwa silicon carbide makhiristo amodzi amatha kuzindikirika kuti apange zinthu zazikulu, zapamwamba zamtundu umodzi wa kristalo.

Kukula kokhazikika pamakristali a silicon carbide ndi njira ya PVT ndikofunikira kwambiri popanga makristasi amodzi a silicon carbide, ndipo amathandizira kwambiri kupeza zida zapamwamba, zazikulu zazikuluzikulu za silicon carbide single-crystal.

8inch SiCseed crystal yomwe timapereka ndiyosowa kwambiri pamsika pano. Chifukwa chazovuta zaukadaulo, mafakitale ambiri sangathe kupereka makhiristo akulu akulu. Komabe, chifukwa cha ubale wathu wautali komanso wapamtima ndi fakitale ya silicon carbide yaku China, titha kupatsa makasitomala athu chowotcha chambewu cha 8-inch silicon carbide. Ngati muli ndi zosowa zilizonse, chonde omasuka kulankhula nafe. Titha kugawana nanu kaye zomwe mwatsimikiza.
