Semicera e fana ka liaparo tse khethehileng tsa tantalum carbide (TaC) bakeng sa likarolo tse fapaneng le bajari.Semicera e etellang pele ts'ebetso ea ho roala e nolofalletsa liphahlo tsa tantalum carbide (TaC) ho finyella bohloeki bo phahameng, botsitso ba mocheso o phahameng le mamello e phahameng ea lik'hemik'hale, ho ntlafatsa boleng ba sehlahisoa sa likristale tsa SIC / GAN le likarolo tsa EPI (Sesila sa TaC se koahetsoeng ke graphite), le ho lelefatsa bophelo ba likarolo tsa bohlokoa tsa reactor. 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.
Ka ho fihla ha li-wafers tsa 8-inch silicon carbide (SiC), litlhoko tsa mekhoa e fapaneng ea semiconductor li se li le thata haholo, haholo-holo bakeng sa mekhoa ea epitaxy moo mocheso o ka fetang likhato tse 2000 tsa Celsius. Lisebelisoa tsa setso tsa susceptor, tse kang graphite e koahetsoeng ka silicon carbide, li na le ho fokotseha ha mocheso ona o phahameng, ho senya ts'ebetso ea epitaxy. Leha ho le joalo, CVD tantalum carbide (TaC) e sebetsana le taba ena ka katleho, e mamella mocheso o fihlang ho likhato tse 2300 tsa Celsius le ho fana ka bophelo bo bolelele ba ts'ebeletso. Ikopanye le Semicera's Tantalum Carbide TaC CVD Coating Wafer Susceptorho ithuta haholoanyane ka litharollo tsa rona tse tsoetseng pele.
Ka mor'a lilemo tsa tsoelo-pele, Semicera e hapile theknoloji eaCVD TaCka matsapa a kopanetsweng a lefapha la R&D. Litšitiso li bonolo ho etsahala ts'ebetsong ea kholo ea li-wafers tsa SiC, empa ka mor'a ho li sebelisaTaC, phapang ke ea bohlokoa. Ka tlase ke papiso ea li-wafers tse nang le TaC le ntle le eona, hammoho le likarolo tsa Simicera bakeng sa kholo e le 'ngoe ea kristale.
