Ts'ebeliso ea tantalum carbide TaC coating ke ho rarolla bothata le ho ntlafatsa boleng ba kholo ea kristale, mme Semicera e se e rarollotse theknoloji ea tantalum carbide coating (CVD), e fihletseng boemo bo holimo ba machabeng.
Graphite ke thepa e ntle haholo ea mocheso o phahameng, empa e oxidize habonolo mocheso o phahameng. Le ka har'a libopi tsa vacuum tse nang le khase ea inert, e ntse e ka kena butle ka oxidation. Ho sebelisa lesela la CVD tantalum carbide (TaC) ho ka sireletsa ka katleho substrate ea graphite, ho fana ka khanyetso e tšoanang ea mocheso o phahameng joaloka graphite. TaC e boetse ke thepa e sa sebetseng, ho bolelang hore e ke ke ea itšoara ka likhase tse kang argon kapa hydrogen mocheso o phahameng.PatlisisoTantalum Carbide CVD Coating EPI Susceptor hona joale!
