Sekoahelo sa Silicon Carbide (SiC) ke Eng?
Sejana sa Silicon Carbide Crucible ke setshelo sa letsopa se sebetsang hantle se entsweng ka thepa ya SiC e hlwekileng haholo. E entswe ka ho kgetheha ho sebetsa tlasa maemo a feteletseng a mocheso le dikhemikhale moo thepa ya setso e ka hlolehang. Silicon carbide e fana ka motswako o ikgethang wa ho hanyetsa mocheso o phahameng, ho tsamaisa mocheso hantle, matla a phahameng a mechini, le ho se sebetse hantle ha dikhemikhale. Dibopeho tsena di dumella dijana tsa SiC ho boloka botsitso ba sebopeho le botsitso ba sebopeho esita le ha di pepesehetse mocheso o fetang 1,600°C, e leng se etsang hore di be ntle bakeng sa ditshebediso tse tswetseng pele tsa tlhahiso ya di-semiconductor.
Litšebeliso tse Tloaelehileng tsa Li-Crucible tsa SiC ho Tlhahisong ea Semiconductor
E 'ngoe ea lits'ebetso tsa bohlokoa ka ho fetisisa tsa li-crucible tsa SiC ke lits'ebetsong tsa kholo ea kristale. Tlhahisong ea li-substrate tsa silicon carbide, phofo ea SiC e hloekileng haholo e futhumatsoa ho fihlela mochesong o phahameng haholo, moo sublimation le recrystallization li etsahalang ho etsa likristale tse le 'ngoe. Ho pholletsa le ts'ebetso ena, sebolai se sebetsa e le sebopeho sa mantlha sa polokelo, se fana ka tikoloho e laoloang ea mocheso e tšehetsang ho thehoa ha kristale ha e ntse e fokotsa likotsi tsa tšilafalo. Boleng ba sebolai bo ka ama haholo bongata ba sekoli, ho tšoana ha kristale, le chai ea wafer.
Ka nqane ho kgolo ya kristale ya SiC, di-crucible tsa silicon carbide di sebediswa haholo tlhahisong ya di-semiconductor tse kopaneng, ho kenyeletswa gallium nitride (GaN), aluminium nitride (AlN), le thepa e meng e tswetseng pele e sebediswang disebedisweng tsa elektroniki tse matla le tsa optoelectronic. Ho hanyetsa ha tsona ka tsela e babatsehang dikhemistri tsa tshebetso e senyang le ho tshoha ha mocheso ho etsa hore di lokele mefuta e fapaneng ya ditsamaiso tsa mouoane wa mocheso o phahameng le tsa ho tsamaisa mouoane wa mmele (PVT).
