Zipangizo Zimasintha Tsogolo

Silicon carbide (SiC) ndi chinthu chatsopano cha semiconductor. Silicon carbide ili ndi kusiyana kwakukulu kwa bandi (pafupifupi silicon nthawi 3), mphamvu yayikulu yofunikira kwambiri (pafupifupi silicon nthawi 10), kutenthetsa kwambiri kwamafuta (pafupifupi silicon nthawi 3). Ndikofunikira kwambiri m'badwo wotsatira wa semiconductor. Zovala za SiC zimagwiritsidwa ntchito kwambiri mumakampani a semiconductor ndi ma photovoltaics a dzuwa. Makamaka, ma susceptors omwe amagwiritsidwa ntchito pakukula kwa epitaxial kwa ma LED ndi Si single crystal epitaxy amafuna kugwiritsa ntchito zokutira za SiC. Chifukwa cha kukwera kwamphamvu kwa ma LED pakuwunikira ndikuwonetsa makampani, komanso kutukuka kwakukulu kwamakampani opanga ma semiconductor,SiC coating mankhwalaziyembekezo ndi zabwino kwambiri.

APPLICATION FIELD

Kugwiritsa ntchito ndi magwiridwe antchito Zogulitsa ndi kugwiritsa ntchito

Si single crystal industry, GaN, AlN, safire ndi zina za MOCVD. - Graphite maziko zokutira kwa single crystal silicon epitaxial kukula

Ntchito yayikulu: kuyera kwakukulu, kukana kukokoloka, kukhathamiritsa kwamafuta apamwamba, - Njira ya MOCVD, zokutira zoyambira za graphite za kukula kwa GaN epitaxial

kutentha kwambiri kukana, kutsika kwamafuta owonjezera kowonjezera.

Kuyera kwa zokutira za SiC pa graphite pogwiritsa ntchito CVD ndizokwera kwambiri mpaka 99.9995%. Mapangidwe ake ndi fcc. Mafilimu a SiC omwe amaikidwa pa graphite ndi (111) akuyang'ana monga momwe asonyezedwera mu deta ya XRD (Fig.1) yosonyeza khalidwe lake lapamwamba la crystalline. Makulidwe a filimu ya SiC ndi yofanana kwambiri monga momwe tawonetsera mkuyu.

Zambiri za SEM za filimu yopyapyala ya CVD SiC, kukula kwa kristalo ndi 2 ~ 1 Opm

Chithunzi 2: makulidwe yunifolomu ya mafilimu a SiC

Kapangidwe ka kristalo ka filimu ya CVD SiC ndi mawonekedwe a nkhope ya cubic, ndipo mawonekedwe akukula kwa filimu ali pafupi ndi 100%

SEM ndi XRD ya kanema wa beta-SiC pa graphite

SINGLE CRYSTAL SILICON EPITAXIAL BASE

Zochita zamalonda ndi chiyembekezo chogwiritsa ntchito.

Silicon carbide (SiC) yokutidwamaziko ndiye maziko abwino kwambiri a silicon imodzi ya crystal ndi GaN epitaxy, yomwe ndi gawo lalikulu la ng'anjo ya epitaxy. Pansi pake ndi chofunikira chopangira silicon ya monocrystalline pamabwalo akulu ophatikizika. Ili ndi kuyera kwakukulu, kukana kutentha kwambiri, kukana kwa dzimbiri, kulimba kwa mpweya wabwino ndi zina zabwino zakuthupi.

Kugwiritsidwa ntchito ndi mankhwala

Graphite m'munsi zokutira kwa crystal silicon epitaxial kukula Oyenera makina a Aixtron, etc. Kupaka makulidwe: 90 ~ 150um M'mimba mwake mwa chigwa chophwanyika ndi 55mm.
