Gallium Nitride (GaN) Epitaxial E Hōlile ka Sapphire Wafers 4inch 6inch bakeng sa MEMS
Thepa ea GaN ka Sapphire Wafers
● Tšebeliso e Ntle:Lisebelisoa tse thehiloeng ho GaN li fana ka matla a fetang a mahlano ho feta lisebelisoa tse thehiloeng ka silicon, tse matlafatsang ts'ebetso lits'ebetsong tse fapaneng tsa elektroniki, ho kenyeletsoa amplification ea RF le optoelectronics.
●Wide Bandgap:Sehlopha se pharaletseng sa GaN se etsa hore ho be le ts'ebetso e phahameng ho mocheso o phahameng, ho etsa hore e be e loketseng bakeng sa lisebelisoa tse phahameng tsa matla le tse phahameng.
●Tsamaiso:Bokhoni ba GaN ba ho sebetsana le maemo a feteletseng (mocheso o phahameng le mahlaseli a kotsi) ho netefatsa ts'ebetso ea nako e telele libakeng tse thata.
●Bonyane:GaN e lumella tlhahiso ea lisebelisoa tse ngata tse kopanetsoeng le tse bobebe ha li bapisoa le lisebelisoa tsa setso tsa semiconductor, ho thusa lisebelisoa tsa elektronike tse nyenyane le tse matla haholoanyane.
Kakaretso
Gallium Nitride (GaN) e ntse e hlaha e le semiconductor ea khetho bakeng sa lisebelisoa tse tsoetseng pele tse hlokang matla a phahameng le katleho, tse kang li-module tsa RF front-end, mekhoa ea puisano e potlakileng, le mabone a LED. Li-wafers tsa GaN epitaxial, ha li lengoa holim'a li-sapphire substrates, li fana ka motsoako oa mocheso o phahameng oa mocheso, motlakase o phahameng oa ho senya, le karabo e pharaletseng ea maqhubu, e leng senotlolo sa ts'ebetso e nepahetseng ea lisebelisoa tsa puisano tse se nang mohala, li-radar le li-jammer. Li-wafer tsena li fumaneha ka bophara ba 4-inch le 6-inch, ka botenya ba GaN bo fapaneng ho fihlela litlhoko tse fapaneng tsa tekheniki. Thepa e ikhethang ea GaN e e etsa mokhethoa oa mantlha oa bokamoso ba lisebelisoa tsa elektroniki.

Q&A
Q1: Melemo ea bohlokoa ea ho sebelisa GaN ho feta li-semiconductors tse thehiloeng ho silicon ke life?
A1: GaN e fana ka melemo e mengata ea bohlokoa ho feta silicon, ho kenyelletsa le bandgap e pharaletseng, e e lumellang ho sebetsana le maemo a phahameng a ho senya le ho sebetsa ka katleho mocheso o phahameng. Sena se etsa hore GaN e be e loketseng bakeng sa lits'ebetso tsa matla a holimo, a maqhubu a phahameng joalo ka li-module tsa RF, liamplifiers tsa motlakase le li-LED. Bokhoni ba GaN ba ho sebetsana le matla a phahameng a matla le bona bo thusa lisebelisoa tse nyane le tse sebetsang hantle ha li bapisoa le mefuta e meng e thehiloeng ho silicon.
Q2: Na GaN on Sapphire wafers e ka sebelisoa lits'ebetsong tsa MEMS (Micro-Electro-Mechanical Systems)?
A2: E, GaN on Sapphire wafers e loketse lits'ebetso tsa MEMS, haholo-holo moo ho hlokahalang matla a phahameng, botsitso ba mocheso le lerata le tlase. Ho tšoarella ha thepa le ho sebetsa hantle libakeng tse nang le maqhubu a holimo ho etsa hore e be e loketseng lisebelisoa tsa MEMS tse sebelisoang puisanong e se nang mohala, ea sensing le ea radar.
Q3: Ke lisebelisoa life tse ka bang teng tsa GaN puisanong e se nang mohala?
A3: GaN e sebelisoa haholo ho RF front-end modules bakeng sa puisano e se nang mohala, ho kenyeletsoa lisebelisoa tsa 5G, lisebelisoa tsa radar le li-jammers. Matla a eona a phahameng a matla le mocheso oa mocheso o etsa hore e be o phethahetseng bakeng sa lisebelisoa tse phahameng, tse nang le maqhubu a phahameng, tse nolofalletsang ts'ebetso e ntlafetseng le lintlha tse nyenyane tsa mefuta ha li bapisoa le litharollo tse thehiloeng ho silicon.
Q4: Ke linako life tse etellang pele le palo e tlase ea odara bakeng sa GaN ho li-wafers tsa Sapphire?
A4: Linako tse etellang pele le palo e tlase ea odara li fapana ho latela boholo ba liphaephe, botenya ba GaN, le litlhoko tse khethehileng tsa bareki. Ka kopo ikopanye le rona ka kotloloho bakeng sa lintlha tse qaqileng tsa litheko le ho fumaneha ho latela lintlha tsa hau.
Q5: A na nka fumana botenya ba GaN layer kapa maemo a doping?
A5: E, re fana ka tlhophiso ea botenya ba GaN le maemo a doping ho fihlela litlhoko tse ikhethileng tsa kopo. Ka kopo, re tsebise litlhaloso tseo u li batlang, 'me re tla fana ka tharollo e lokiselitsoeng.
