3inch SiC substrate Yopanga Dia76.2mm 4H-N

Zinthu zazikulu za ma wafer a silicon carbide mosfet a mainchesi atatu ndi izi;

Silicon Carbide (SiC) ndi chipangizo cha semiconductor chomwe chimagwira ntchito bwino kwambiri, chomwe chimadziwika ndi kutentha kwambiri, kuyenda kwa ma elekitironi ambiri, komanso mphamvu zamagetsi zomwe zimawonongeka kwambiri. Zinthu zimenezi zimapangitsa kuti ma wafer a SiC akhale abwino kwambiri pakugwiritsa ntchito mphamvu zambiri, ma frequency ambiri, komanso kutentha kwambiri. Makamaka mu 4H-SiC polytype, kapangidwe kake ka kristalo kamapereka magwiridwe antchito abwino kwambiri amagetsi, zomwe zimapangitsa kuti ikhale chinthu chomwe chimasankhidwa kwambiri pazida zamagetsi zamagetsi.

Wafer wa Silicon Carbide 4H-N wa mainchesi atatu ndi wafer wopangidwa ndi nayitrogeni wokhala ndi conductivity ya mtundu wa N. Njira yopangira doping iyi imapatsa wafer kuchuluka kwa ma elekitironi ambiri, motero imawonjezera magwiridwe antchito a chipangizocho. Kukula kwa wafer, pa mainchesi atatu (m'mimba mwake wa 76.2 mm), ndi gawo lomwe limagwiritsidwa ntchito kwambiri mumakampani opanga ma semiconductor, loyenera njira zosiyanasiyana zopangira.

Wafer wa Silicon Carbide 4H-N wa mainchesi atatu umapangidwa pogwiritsa ntchito njira ya Physical Vapor Transport (PVT). Njirayi imaphatikizapo kusintha ufa wa SiC kukhala makhiristo amodzi kutentha kwambiri, kuonetsetsa kuti waferyo ndi wabwino komanso wofanana. Kuphatikiza apo, makulidwe a wafer nthawi zambiri amakhala pafupifupi 0.35 mm, ndipo pamwamba pake pamakhala kupukutidwa mbali ziwiri kuti pakhale kusalala kwambiri komanso kusalala, komwe ndikofunikira kwambiri pakupanga ma semiconductor pambuyo pake.

Mitundu yosiyanasiyana ya ma wafer a Silicon Carbide 4H-N a mainchesi atatu ndi yokulirapo, kuphatikizapo zida zamagetsi zamphamvu kwambiri, masensa otentha kwambiri, zida za RF, ndi zida zamagetsi. Kugwira ntchito bwino komanso kudalirika kwake kumathandiza kuti zidazi zizigwira ntchito bwino pakakhala zovuta kwambiri, kukwaniritsa kufunikira kwa zida zamagetsi zamagetsi zamphamvu kwambiri m'makampani amakono amagetsi.

Tikhoza kupereka 4H-N 3inch SiC substrate, mitundu yosiyanasiyana ya ma wafers a substrate stock. Tikhozanso kukonza zosintha malinga ndi zosowa zanu. Takulandirani mafunso!
