Semicera's 6 Inch N-type SiC Wafer e eme ka pele ho theknoloji ea semiconductor. E entsoe bakeng sa ts'ebetso e nepahetseng, sephaphatha sena se ipabola ka ho sebelisa matla a holimo, maqhubu a holimo le mocheso o phahameng, se bohlokoa bakeng sa lisebelisoa tse tsoetseng pele tsa elektroniki.
Sephepana sa rona sa 6 Inch N-mofuta oa SiC se na le motsamao o phahameng oa elektronike le ho hanyetsa ho fokolang, e leng litekanyetso tsa bohlokoa bakeng sa lisebelisoa tsa motlakase tse kang MOSFET, diode le likarolo tse ling. Thepa ena e netefatsa phetoho e sebetsang ea matla le ho fokotsa mocheso oa mocheso, ho matlafatsa ts'ebetso le nako ea bophelo ea lisebelisoa tsa elektronike.
Ts'ebetso e matla ea taolo ea boleng ba Semicera e netefatsa hore sephaphatha se seng le se seng sa SiC se boloka bokhabane bo holimo le bofokoli bo fokolang. Tlhokomelo ena e hlokolosi ea lintlha e netefatsa hore li-wafers tsa rona li fihlela litlhoko tse thata tsa liindasteri tse kang tsa makoloi, sefofane le likhokahano tsa mehala.
Ntle le thepa ea eona e phahameng ea motlakase, sephaphatha sa SiC sa mofuta oa N se fana ka botsitso bo matla ba mocheso le ho hanyetsa mocheso o phahameng, e leng se etsang hore e be se loketseng libakeng tseo lisebelisoa tse tloaelehileng li ka hlolehang ho tsona. Bokhoni bona bo bohlokoa haholo lits'ebetsong tse amanang le ts'ebetso ea maqhubu a holimo le a matla a phahameng.
Ka ho khetha Semicera's 6 Inch N-type SiC Wafer, u tsetela ho sehlahisoa se emelang tlhōrō ea boqapi ba semiconductor. Re ikemiseditse ho fana ka diboloko tsa ho aha disebediswa tsa moraorao, ho netefatsa hore balekane ba rona diindastering tse fapaneng ba fihlella disebediswa tse molemo ka ho fetisisa bakeng sa ntshetsopele ya bona ya thekenoloji.
