Izinhlelo zokusebenza
1. Ucwaningo Nentuthuko
Ingot yebanga locwaningo 4H-SiC ilungele amalebhu ezemfundo nezimboni agxile ekuthuthukisweni kwedivayisi okusekelwe ku-SiC. Ikhwalithi yayo ephakeme yekristalu inika amandla ukuhlolwa okunembile kwezakhiwo ze-SiC, njenge:
Izifundo zokuhamba zenkampani yenethiwekhi.
Izindlela zokubonisa iphutha kanye namasu okunciphisa.
Ukuthuthukiswa kwezinqubo zokukhula kwe-epitaxial.
2. I-Dummy Substrate
I-ingot ye-dummy-grade isetshenziswa kakhulu ekuhloleni, ekulinganisweni nasekusetshenzisweni kwe-prototyping. Kungenye indlela eyongayo:
Inqubo yokulinganisa ipharamitha ku-Chemical Vapor Deposition (CVD) noma i-Physical Vapor Deposition (PVD).
Ukuhlola izinqubo zokufaka nokupholisha ezindaweni zokukhiqiza.
3. Amandla kagesi
Ngenxa ye-bandgap ebanzi kanye nokusebenza okuphezulu kwe-thermal, i-4H-SiC iyitshe legumbi lama-electronics amandla, njenge:
High-voltage MOSFETs.
I-Schottky Barrier Diodes (SBDs).
I-Junction Field-Effect Transistors (JFETs).
Izicelo zifaka ama-inverter emoto kagesi, ama-solar inverter, namagridi ahlakaniphile.
4. High-Frequency Amadivayisi
Ukuhamba kwama-electron aphezulu kanye nokulahlekelwa amandla aphansi kuyenza ifanelekele:
