1. Lipatlisiso le Ntlafatso
Ingot ea sehlopha sa lipatlisiso sa 4H-SiC e loketse lilaboratori tsa thuto le tsa indasteri tse shebaneng le nts'etsopele ea lisebelisoa tse thehiloeng ho SiC. Boleng ba eona bo phahameng ba kristale bo nolofalletsa liteko tse nepahetseng ho thepa ea SiC, joalo ka:
Lithuto tsa motsamao oa Carrier.
Litšobotsi tsa bofokoli le mekhoa ea ho fokotsa.
Ntlafatso ea mekhoa ea kholo ea epitaxial.
2. Dummy Substrate
Ingot ea boemo ba dummy e sebelisoa haholo litekong, ho lekanya, le lits'ebetsong tsa prototyping. Ke khetho e baballang litšenyehelo bakeng sa:
Tekanyo ea paramethara ea ts'ebetso ho Chemical Vapor Deposition (CVD) kapa Physical Vapor Deposition (PVD).
Ho lekola lits'ebetso tsa etching le polishing libakeng tsa tlhahiso.
3. Matla a Elektronike
Ka lebaka la sekhahla sa eona se sephara le phepelo e phahameng ea mocheso, 4H-SiC ke lejoe la sekhutlo la lisebelisoa tsa elektroniki tse kang:
Li-MOSFET tse matla haholo.
Schottky Barrier Diodes (SBDs).
