150mm 200mm 6inch 8inch GaN kwiSilicon Epi-layer wafer Gallium nitride epitaxial wafer
Indlela yokuvelisa
Inkqubo yokwenziwa kwemveliso ibandakanya ukukhulisa iileya ze-GaN kwi-substrate yesafire kusetyenziswa ubuchule obuphambili obufana nentsimbi-organic chemical deposition deposition (MOCVD) okanye i-molecular beam epitaxy (MBE). Inkqubo yokubeka iqhutyelwa phantsi kweemeko ezilawulwayo ukuze kuqinisekiswe umgangatho ophezulu we-crystal kunye nefilimu efanayo.
Izicelo ze-6inch ze-GaN-On-Sapphire: Ii-chips ze-sapphire substrate ze-6 intshi zisetyenziswa ngokubanzi kwii-microwave zonxibelelwano, iinkqubo ze-radar, iteknoloji engenazintambo kunye ne-optoelectronics.
Ezinye izicelo eziqhelekileyo ziquka
1. I-amplifier yamandla e-Rf
2. Ishishini lokukhanyisa i-LED
3. Izixhobo zonxibelelwano zenethiwekhi ezingenazingcingo
4. Izixhobo zombane kwindawo yobushushu obuphezulu
5. Izixhobo ze-Optoelectronic
Iimpawu zemveliso
- Ubungakanani: I-substrate diameter yi-6 intshi (malunga ne-150 mm).
- Umgangatho womphezulu: Umphezulu ugudiswe kakuhle ukunika umgangatho obalaseleyo wesipili.
- Ukutyeba: Ubukhulu bomaleko we-GaN bunokwenziwa ngokweemfuno ezithile.
- Ukupakishwa: I-substrate ihlanganiswe ngokucophelela kunye nezinto ezichasene ne-static ukukhusela umonakalo ngexesha lokuthutha.
- Imiphetho yokuma: I-substrate inemida ethile yokumisa eququzelela ulungelelwaniso kunye nokusebenza ngexesha lokulungiswa kwesixhobo.
-Ezinye iiparamitha: Iiparamitha ezithile ezinjengokubhitya, ukumelana noxinzelelo kunye noxinzelelo lwe-doping zinokuhlengahlengiswa ngokweemfuno zabathengi.
Ngeempawu zabo eziphathekayo eziphezulu kunye nezicelo ezahlukeneyo, i-6-intshi ye-sapphire substrate wafers yinto ethembekileyo yokuphuhliswa kwezixhobo eziphezulu ze-semiconductor kumashishini ahlukeneyo.
