SiC Yokutidwa

VET ENERGY, kampani yotsogola yopanga zokutira za CVD SIC ku China

Zipangizo Zimasintha Tsogolo

Silicon carbide (SiC) ndi chinthu chatsopano cha semiconductor. Silicon carbide ili ndi band gap yayikulu (pafupifupi katatu kuposa silicon), high critical field strength (pafupifupi katatu kuposa silicon), high thermal conductivity (pafupifupi katatu kuposa silicon). Ndi chinthu chofunikira kwambiri cha semiconductor cha m'badwo wotsatira. Zophimba za SiC zimagwiritsidwa ntchito kwambiri mumakampani opanga semiconductor ndi solar photovoltaics. Makamaka, zophimba zomwe zimagwiritsidwa ntchito pakukula kwa epitaxial kwa ma LED ndi Si single crystal epitaxy zimafuna kugwiritsa ntchito SiC coating. Chifukwa cha kukwera kwamphamvu kwa ma LED mumakampani opanga magetsi ndi zowonetsera, komanso chitukuko champhamvu cha makampani opanga semiconductor,Chovala cha SiCMapeto ake ndi abwino kwambiri.

MUNDA WOPHUNZIRA

Kugwiritsa ntchito ndi magwiridwe antchito a chinthucho Kugwiritsa ntchito ndi kugwiritsa ntchito zinthu

Si single crystal industry, GaN, AlN, safiro ndi zina za MOCVD. -Graphite base covering for single crystal silicon epitaxial growth

Kuchita bwino kwakukulu: kuyera kwambiri, kukana kukokoloka kwa nthaka, kutentha kwambiri, - MOCVD process, graphite base covering kuti GaN epitaxial growth ikule bwino

kukana kutentha kwambiri, kuchuluka kwa kutentha kochepa.

Chiyero, Kapangidwe ka SEM, kusanthula makulidwe aChophimba cha SiC

Kuyera kwa zophimba za SiC pa graphite pogwiritsa ntchito CVD kuli kokwera kufika pa 99.9995%. Kapangidwe kake ndi fcc. Mafilimu a SiC opakidwa pa graphite ali ndi (111) motsatira zomwe zawonetsedwa mu data ya XRD (Chithunzi 1) zomwe zikusonyeza kuti ndi yapamwamba kwambiri. Kukhuthala kwa filimu ya SiC ndi kofanana kwambiri monga momwe zasonyezedwera mu Chithunzi 2.

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

Chithunzi 2: makulidwe ofanana a mafilimu a SiC

Kapangidwe ka kristalo ka filimu ya CVD SiC ndi kapangidwe ka cubic kozungulira nkhope, ndipo kukula kwa filimuyo kuli pafupi 100%.

CHIGAWO CHA EPITAXIAL CHA KHRISTAL SILICON CHIMODZI

Kugwira ntchito kwa malonda ndi chiyembekezo cha kugwiritsa ntchito.

Chokutidwa ndi silicon carbide (SiC)Maziko ake ndi maziko abwino kwambiri a silicon imodzi ya kristalo ndi GaN epitaxy, yomwe ndi gawo lalikulu la ng'anjo ya epitaxy. Maziko ake ndi chowonjezera chofunikira kwambiri pakupanga silicon ya monocrystalline pamabwalo akuluakulu ophatikizika. Ali ndi chiyero chapamwamba, kukana kutentha kwambiri, kukana dzimbiri, kulimba kwa mpweya wabwino komanso zinthu zina zabwino kwambiri.

Kugwiritsa ntchito ndi kugwiritsa ntchito kwa chinthucho

Chophimba maziko a graphite cha kukula kwa silicon epitaxial imodzi. Choyenera makina a Aixtron, ndi zina zotero. Kukhuthala kwa chophimba: 90~150um. M'mimba mwake mwa chibowo cha wafer ndi 55mm.

Zinthu zomwe zili mu malonda

Kukana kutentha kwambiri, kukana dzimbiri, kukhala ndi moyo wautali, kumatha kukweza ubwino ndi kutulutsa kwa wafer. Ndi kuchuluka kochepa kwambiri kwa kutentha, kukana kutentha kwambiri, kukana kukalamba kwambiri, kutchinjiriza bwino, kukhazikika bwino kwa mankhwala, pafupi ndi utoto wofiirira (wofiira) kunja komwe kuwala kumaonekera.

Utumiki Wachangu

Kuti mupeze oda yanu isanakwane, gulu lathu la akatswiri ogulitsa likhoza kuyankha funso lanu mkati mwa mphindi 50-100 panthawi yogwira ntchito komanso mkati mwa maola 12 panthawi yotseka. Yankho lachangu komanso laukadaulo lidzakuthandizani kupeza kasitomala wanu ndi njira yabwino kwambiri komanso yogwira ntchito bwino.

Pa nthawi yoyitanitsa zinthu, gulu lathu la akatswiri lidzajambula zithunzi masiku atatu kapena asanu aliwonse kuti mudziwe zambiri zokhudza kupanga zinthuzo ndikupereka zikalata mkati mwa maola 36 kuti zitsimikizire momwe kutumiza kukuyendera. Timayang'anitsitsa kwambiri ntchito yogulitsa zinthu pambuyo pogulitsa.

Pa gawo la malonda atatha, gulu lathu lautumiki nthawi zonse limalumikizana nanu pafupi ndipo nthawi zonse limakuthandizani kupeza chithandizo chanu. Utumiki wathu waukadaulo wotsatsa malonda umaphatikizapo kutumiza mainjiniya athu kuti akuthandizeni kuthetsa mavuto pamalopo. Chitsimikizo chathu ndi miyezi 12 mutatumiza.

Tsatanetsatane wa phukusi

Ningbo VET Energy Technology Co., Ltd ndi kampani yopanga zinthu za graphite, makamaka popanga zinthu zatsopano za semiconductor komanso kuyang'ana kwambiri pakufufuza ndi kupanga zokutira za SiC. Zinthu zazikulu za kampaniyo ndi ma susceptor okhala ndi SiC omwe amagwiritsidwa ntchito pamakampani a LED ndi silicon monocrystalline. Filimu ya SiC yomwe imagwiritsidwa ntchito pamakampani a LED ndi silicon monocrystalline ndi cubic phase, yomwe ili ndi kapangidwe ka lattice kofanana ndi diamondi, ndipo kuuma kwake kuli bwino ngati diamondi. Silicon carbide ndiye chinthu chokhwima kwambiri cha semiconductor, ndipo chili ndi mwayi wogwiritsidwa ntchito kwambiri mumakampani a semiconductor. Kuphatikiza apo, silicon carbide ili ndi kutentha kwakukulu, kutentha pang'ono kowonjezera, kutentha kwambiri (pafupifupi madigiri 2700 Celsius), komanso kukana dzimbiri bwino. Zopangira zokutira za silicon carbide za kampaniyo zimagwiritsidwanso ntchito kwambiri mumakampani opanga ndege, photovoltaic, mphamvu za nyukiliya, njanji yothamanga kwambiri, magalimoto ndi mafakitale ena.

Mafunso Ofunsidwa Kawirikawiri

Kodi muli ndi oda yocheperako?

Inde, tikufuna kuti maoda onse apadziko lonse lapansi azikhala ndi kuchuluka kocheperako koyitanitsa nthawi zonse.

Kodi mungapereke zikalata zoyenera?

Inde, titha kupereka zikalata zambiri kuphatikizapo Zikalata Zowunikira / Kutsatira; Inshuwalansi; Chiyambi, ndi zikalata zina zotumizira kunja komwe kukufunika.

Kodi nthawi yotsogolera ndi yotani?

Pa zitsanzo, nthawi yoperekera chithandizo ndi masiku 7. Pakupanga zinthu zambiri, nthawi yoperekera chithandizo ndi masiku 15-25 mutalandira ndalama zolipirira. Nthawi yoperekera chithandizo imayamba kugwira ntchito tikalandira ndalama zanu, ndipo timalandira chilolezo chanu chomaliza cha zinthu zanu. Nthawi zonse tidzayesetsa kukwaniritsa zosowa zanu. Nthawi zambiri timatha kutero.

Kodi mumalandira njira zotani zolipirira?

Mukhoza kulipira ku akaunti yathu ya banki, Western Union kapena PayPal:
30% yosungira pasadakhale, 70% yotsala musanatumize kapena motsutsana ndi kopi ya B/L.

Kodi chitsimikizo cha malonda ndi chiyani?

Timapereka chitsimikizo cha zipangizo zathu ndi luso lathu. Kudzipereka kwathu ndikukwaniritsa zomwe mukufuna ndi zinthu zathu. Kaya chitsimikizo chili chotani, ndi chikhalidwe cha kampani yathu kuthetsa mavuto onse a makasitomala kuti aliyense akhutire.

Kodi mukutsimikiza kuti zinthu zidzatumizidwa bwino komanso motetezeka?

Inde, nthawi zonse timagwiritsa ntchito ma CD apamwamba kwambiri otumizira kunja. Timagwiritsanso ntchito ma CD apadera oika zinthu zoopsa komanso otumiza zinthu zozizira zovomerezeka pazinthu zomwe zimakhudzidwa ndi kutentha. Ma CD apadera komanso zofunikira zoyika zinthu zomwe sizili zokhazikika zitha kubweretsa ndalama zina zowonjezera.

Nanga bwanji za ndalama zotumizira?

Mtengo wotumizira umadalira njira yomwe mwasankha yopezera katundu. Nthawi zambiri njira yachangu kwambiri komanso yokwera mtengo kwambiri. Kutumiza katundu panyanja ndiyo njira yabwino kwambiri yopezera katundu wambiri. Mitengo yotumizira katundu tingakupatseni pokhapokha ngati tikudziwa zambiri za kuchuluka kwake, kulemera kwake, ndi njira yake. Chonde titumizireni uthenga kuti mudziwe zambiri.
