yambitsani

XKH imapereka magawo a 4-inch, 6-inch, ndi 8-inch SiC mbewu yokhala ndi doping yamtundu wa N-type/P, kukwaniritsa milingo ya resistivity ya 0.01-0.1 Ω·cm ndi kusasunthika kwa dislocation pansi pa 500 cm⁻², kuwapanga kukhala abwino popanga MOSFETs, Schottky Barriers Digital Ntchito yathu yophatikizika yophatikizika imakhudza kukula kwa kristalo, kuwotcha, kupukuta, ndikuwunika, ndikutha kupanga pamwezi kupitilira zowotcha 5,000 kuti zikwaniritse zofuna zosiyanasiyana zamabungwe ofufuza, opanga ma semiconductor, ndi makampani opanga mphamvu zongowonjezwdwa.

Kuphatikiza apo, timapereka mayankho okhazikika, kuphatikiza:

Kusintha kwa Crystal (4H-SiC, 6H-SiC)

Doping wapadera (Aluminiyamu, Nayitrogeni, Boron, etc.)

Kupukuta kosalala kwambiri (Ra <0.5 nm)

XKH imathandizira potengera zitsanzo, kulumikizana ndiukadaulo, ndi mawonekedwe ang'onoang'ono kuti apereke mayankho okhathamiritsa a gawo lapansi la SiC.
