2 inchi Sic silicon carbide substrate 6H-N Mtundu 0.33mm 0.43mm kupukuta mbali ziwiri Kutentha kwakukulu kugwiritsa ntchito mphamvu zochepa

Kufotokozera Kwachidule:

Silicon carbide (SiC) ndi chipangizo cha semiconductor chokhala ndi mipata yayikulu yokhala ndi kutentha kwabwino komanso kukhazikika kwa mankhwala.6H-Nzimasonyeza kuti kapangidwe kake ka kristalo ndi kozungulira (6H), ndipo "N" imasonyeza kuti ndi chinthu cha semiconductor cha mtundu wa N, chomwe nthawi zambiri chimapezeka powonjezera nayitrogeni.
Chitsulo cha silicon carbide chili ndi makhalidwe abwino kwambiri monga kukana kuthamanga kwambiri, kukana kutentha kwambiri, kugwira ntchito pafupipafupi, ndi zina zotero. Poyerekeza ndi zinthu za silicon, chipangizo chokonzedwa ndi silicon substrate chingachepetse kutayika ndi 80% ndikuchepetsa kukula kwa chipangizocho ndi 90%. Ponena za magalimoto atsopano amphamvu, silicon carbide ingathandize magalimoto atsopano amphamvu kukhala opepuka ndikuchepetsa kutayika, ndikuwonjezera kuchuluka kwa magalimoto; Pankhani yolumikizirana ya 5G, ingagwiritsidwe ntchito popanga zida zokhudzana nazo; Pakupanga mphamvu ya photovoltaic ikhoza kusintha magwiridwe antchito; Munda wa sitima ungagwiritse ntchito kutentha kwake kwakukulu komanso kukana kuthamanga kwambiri.

Tumizani imelo kwa ife

Mawonekedwe

Izi ndi zizindikiro za 2inch silicon carbide wafer

1. Kuuma: Kuuma kwa Mohs kuli pafupifupi 9.2.
2. Kapangidwe ka kristalo: kapangidwe ka latisi ya hexagonal.
3. Kutentha kwambiri: kutentha kwa SiC kumakhala kwakukulu kuposa kwa silicon, komwe kumathandiza kuti kutentha kutayike bwino.
4. Mpata waukulu wa band: Mpata wa band wa SiC ndi pafupifupi 3.3eV, woyenera kutentha kwambiri, ma frequency ambiri komanso kugwiritsa ntchito mphamvu zambiri.
5. Kugawika kwa magetsi ndi kuyenda kwa ma elekitironi: Kugawika kwa magetsi ndi kuyenda kwa ma elekitironi, koyenera kugwiritsa ntchito zipangizo zamagetsi zamagetsi monga MOSFET ndi IGBTs.
6. Kukhazikika kwa mankhwala ndi kukana kuwala kwa dzuwa: koyenera malo ovuta monga ndege ndi chitetezo cha dziko. Kukana kwa mankhwala, asidi, alkali ndi mankhwala ena osungunulira.
7. Mphamvu yayikulu ya makina: Mphamvu yabwino kwambiri ya makina pa kutentha kwambiri komanso malo opanikizika kwambiri.
Itha kugwiritsidwa ntchito kwambiri pazida zamagetsi zamagetsi zamphamvu kwambiri, zama frequency apamwamba komanso kutentha kwambiri, monga ma ultraviolet photodetectors, ma inverter a photovoltaic, ma PCU a magalimoto amagetsi, ndi zina zotero.

Wafer wa silicon carbide wa mainchesi awiri uli ndi ntchito zingapo.

1. Zipangizo zamagetsi zamagetsi: zimagwiritsidwa ntchito popanga MOSFET, IGBT ndi zida zina zamagetsi zogwira ntchito bwino, zomwe zimagwiritsidwa ntchito kwambiri posintha magetsi ndi magalimoto amagetsi.

Zipangizo za 2.Rf: Mu zida zolumikizirana, SiC ingagwiritsidwe ntchito mu ma amplifiers apamwamba komanso ma amplifiers amphamvu a RF.

3. Zipangizo zamagetsi: monga ma LED okhala ndi SIC, makamaka pakugwiritsa ntchito buluu ndi ultraviolet.

4. Masensa: Chifukwa cha kutentha kwake kwakukulu komanso kukana mankhwala, ma substrates a SiC angagwiritsidwe ntchito popanga masensa otentha kwambiri ndi ntchito zina za masensa.

5. Zankhondo ndi zamlengalenga: chifukwa cha kukana kutentha kwambiri komanso mphamvu zake zambiri, zoyenera kugwiritsidwa ntchito m'malo ovuta kwambiri.

Magawo akuluakulu ogwiritsira ntchito a 6H-N type 2 "SIC substrate akuphatikizapo magalimoto atsopano amphamvu, malo otumizira ndi kusintha magetsi amphamvu kwambiri, katundu woyera, sitima zothamanga kwambiri, ma mota, inverter ya photovoltaic, magetsi a pulse ndi zina zotero.

XKH ikhoza kusinthidwa kukhala makulidwe osiyanasiyana malinga ndi zosowa za makasitomala. Pali njira zosiyanasiyana zoyeretsera ndi kupukuta pamwamba. Pali mitundu yosiyanasiyana ya doping (monga nayitrogeni doping) yomwe imathandizidwa. Nthawi yotumizira ndi masabata 2-4, kutengera momwe mwasinthira. Gwiritsani ntchito zida zosungira zotsutsana ndi static ndi thovu loletsa chivomerezi kuti muwonetsetse kuti pansi pake pali chitetezo. Pali njira zosiyanasiyana zotumizira, ndipo makasitomala amatha kuwona momwe zinthu zilili nthawi yeniyeni kudzera mu nambala yotsatirira yomwe yaperekedwa. Perekani chithandizo chaukadaulo ndi ntchito zolangiza kuti muwonetsetse kuti makasitomala amatha kuthetsa mavuto panthawi yogwiritsa ntchito.
