200mm SiC substrate dummy grade 4H-N 8inch SiC wafer

Tlhaloso e Khutšoanyane:

Silicon carbide substrate e nang le bophara ba lisenthimithara tse 8 (hoo e ka bang 200 mm). Silicon carbide (SiC) substrate ke thepa ea bohlokoa bakeng sa ho etsa lisebelisoa tsa motlakase le lisebelisoa tsa optoelectronic. Li-substrates tsa SiC tsa 8-inch hangata li sebelisoa ho etsa lisebelisoa tsa elektroniki tse matla haholo joalo ka li-MOSFET tsa matla, li-diode tsa motlakase le lisebelisoa tse ling tse sebetsang hantle haholo. Substrate ena e boholo bo boholo e ka ntlafatsa ts'ebetso ea tlhahiso, ea fokotsa litšenyehelo tsa tlhahiso, le ho thusa ho etsa lisebelisoa tse matla haholoanyane. Silicon carbide e na le conductivity e ntle ea mocheso, ho hanyetsa mocheso o phahameng le ho hanyetsa mahlaseli, e leng se etsang hore e be khetho e nepahetseng bakeng sa ho etsa lisebelisoa tse phahameng tsa ts'ebetso.

Mathata a tekheniki a tlhahiso ea substrate ea 8-inch SiC a kenyelletsa:

1. Khōlo ea Crystal: Ho finyella khōlo ea boleng bo phahameng ba kristale e le 'ngoe ea silicon carbide ka bophara bo boholo e ka ba phephetso ka lebaka la ho laola mefokolo le litšila.

2.Wafer Processing: Boholo bo boholo ba li-wafers tsa 8-inch bo hlahisa mathata mabapi le ho tšoana le ho laola sekoli nakong ea ho sebetsa ka liphaephe, tse kang ho polishing, etching, le doping.

3.Material Homogeneity: Ho netefatsa thepa e tsitsitseng le homogeneity ho pholletsa le karolo eohle ea 8-inch SiC substrate e batla ka botsebi mme e hloka taolo e nepahetseng nakong ea ts'ebetso ea tlhahiso.

4.Litšenyehelo: Ho phahamisa li-substrates tsa 8-inch SiC ha u ntse u boloka boleng bo phahameng ba thepa le lihlahisoa li ka ba phephetso ea moruo ka lebaka la ho rarahana le litšenyehelo tsa mekhoa ea tlhahiso.

5.Ho sebetsana le mathata ana a tekheniki ke habohlokoa bakeng sa ho amoheloa ho pharaletseng ha li-substrates tsa SiC tsa 8-inch ka matla a phahameng a ts'ebetso le lisebelisoa tsa optoelectronic.

Re fana ka li-sapphire substrates tse tsoang lifemeng tsa pele tsa China tsa SiC ho kenyeletsoa le Tankeblue. Lilemo tse fetang 10 tsa boemeli li re lumelletse ho boloka kamano e haufi le feme. Re ka u fa li-substrates tsa 6inch le 8inchSiC tseo u li hlokang bakeng sa phepelo ea nako e telele le e tsitsitseng ha u ntse u fana ka theko le theko e ntle ka ho fetisisa.

Tankeblue ke khoebo ea theknoloji e phahameng e sebetsanang le nts'etsopele, tlhahiso le thekiso ea li-chips tsa moloko oa boraro oa semiconductor silicon carbide (SiC). Khampani ke e 'ngoe ea lihlahisoa tse ka sehloohong lefatšeng ka bophara tsa li-wafers tsa SiC.
