Mbewu ya 4H-N Dia205mm SiC yochokera ku China ya P ndi D grade Monocrystaline

Njira ya PVT (Physical Vapor Transport) ndi njira yodziwika bwino yomwe imagwiritsidwa ntchito polima makristalo a silicon carbide single. Mu njira yokulira ya PVT, zinthu za silicon carbide single crystal zimayikidwa mwa kusungunuka ndi kunyamulidwa mozungulira makristalo a mbewu za silicon carbide, kotero kuti makristalo atsopano a silicon carbide single akule motsatira kapangidwe ka makristalo a mbewu.

Mu njira ya PVT, kristalo wa mbewu ya silicon carbide umagwira ntchito yofunika kwambiri ngati poyambira komanso chitsanzo cha kukula, zomwe zimakhudza mtundu ndi kapangidwe ka kristalo womaliza umodzi. Panthawi ya kukula kwa PVT, powongolera magawo monga kutentha, kuthamanga ndi kapangidwe ka mpweya, kukula kwa makristalo amodzi a silicon carbide kumatha kuchitika kuti apange zinthu zazikulu komanso zapamwamba kwambiri za kristalo imodzi.

Njira yokulira yomwe imagwiritsa ntchito makristasi a mbewu za silicon carbide pogwiritsa ntchito njira ya PVT ndi yofunika kwambiri popanga makristasi amodzi a silicon carbide, ndipo imagwira ntchito yofunika kwambiri popanga zipangizo zapamwamba kwambiri za silicon carbide imodzi-kristalo.

Kristalo ya SiCseed ya mainchesi 8 yomwe timapereka ndi yosowa kwambiri pamsika pakadali pano. Chifukwa cha zovuta zaukadaulo, mafakitale ambiri sangapereke makristalo akuluakulu a mbewu. Komabe, chifukwa cha ubale wathu wautali komanso wapafupi ndi fakitale ya silicon carbide yaku China, titha kupatsa makasitomala athu wafer iyi ya silicon carbide seed wafer ya mainchesi 8. Ngati muli ndi zosowa zilizonse, chonde musazengereze kutilankhulana nafe. Tikhoza kugawana nanu zofunikira poyamba.
