Semicera's 4 Inch High Purity Semi-Insulating (HPSI) SiC Double-side Polished Wafer Substrates e entsoe ka boqhetseke ho fihlela litlhoko tse nepahetseng tsa indasteri ea semiconductor. Li-substrates tsena li entsoe ka bokhabane bo ikhethang le bohloeki, li fana ka sethala se nepahetseng bakeng sa lisebelisoa tsa elektroniki tse tsoetseng pele.
Li-wafer tsena tsa HPSI SiC li khetholloa ka mokhoa o phahameng oa ho tsamaisa mocheso le thepa ea ho kenya motlakase, e leng se etsang hore e be khetho e babatsehang bakeng sa lisebelisoa tse phahameng le tse matla haholo. Ts'ebetso ea ho bentša ka mahlakoreng a mabeli e tiisa hore ho na le mahlaku a fokolang a holim'a metsi, e leng a bohlokoa bakeng sa ho ntlafatsa ts'ebetso ea lisebelisoa le ho phela nako e telele.
Bohloeki bo phahameng ba li-wafers tsa Semicera's SiC bo fokotsa bofokoli le litšila, e leng se lebisang ho litefiso tse phahameng tsa chai le ho ts'epahala ha lisebelisoa. Li-substrates tsena li loketse lits'ebetso tse fapaneng, ho kenyeletsoa lisebelisoa tsa microwave, lisebelisoa tsa elektroniki tsa motlakase, le theknoloji ea LED, moo ho nepahala le ho tšoarella ho hlokahalang.
E tsepamisitse maikutlo ho boqapi le boleng, Semicera e sebelisa mekhoa e tsoetseng pele ea tlhahiso ho hlahisa liphaphatha tse fihlelang litlhoko tse thata tsa lisebelisoa tsa elektroniki tsa sejoale-joale. Ho belisoa ka mahlakoreng a mabeli ha ho ntlafatse matla a mochine feela empa hape ho thusa ho kopanya hantle le lisebelisoa tse ling tsa semiconductor.
Ka ho khetha Semicera's 4 Inch High Purity Semi-Insulating HPSI SiC Double-side Polished Wafer Substrates, bahlahisi ba ka sebelisa melemo ea taolo e ntlafalitsoeng ea mocheso le ho kenya motlakase, ba bula tsela bakeng sa nts'etsopele ea lisebelisoa tsa elektroniki tse sebetsang hantle le tse matla haholoanyane. Semicera e ntse e tsoela pele ho etella pele indasteri ka boitlamo ba eona ba boleng le tsoelo-pele ea theknoloji.
