Ma Wafer a SiC a mainchesi awiri, 6H kapena 4H, Ma Substrates a SiC Osateteza Zinthu Pakati pa Dia50.8mm

Ma Wafer a SiC a mainchesi awiri, 6H kapena 4H, Ma Substrates a SiC Osateteza Kanthu Dia50.8mm. Chithunzi Chowonetsedwa

Kufotokozera Kwachidule:

Silicon carbide (SiC) ndi gulu lachiwiri la Gulu IV-IV, ndiye gulu lokhalo lolimba lokhazikika mu Gulu IV la Periodic Table of Elements, Ndi gawo lofunika kwambiri la semiconductor. SiC ili ndi mphamvu zabwino kwambiri zotenthetsera, zamakanika, zamakemikolo ndi zamagetsi, zomwe zimapangitsa kuti ikhale imodzi mwa zipangizo zabwino kwambiri zopangira zida zamagetsi zotentha kwambiri, zama frequency apamwamba, komanso zamagetsi amphamvu kwambiri.

Kugwiritsa ntchito silicon carbide substrate

Chigawo cha silicon carbide chingagawidwe m'magulu a conductive ndi semi-insulating mtundu malinga ndi resistivity. Zipangizo za silicon carbide zoyendetsa magetsi zimagwiritsidwa ntchito makamaka m'magalimoto amagetsi, kupanga mphamvu ya photovoltaic, mayendedwe a sitima, malo osungira deta, kuchaja ndi zomangamanga zina. Makampani opanga magalimoto amagetsi ali ndi kufunikira kwakukulu kwa ma substrates a silicon carbide oyendetsa magetsi, ndipo pakadali pano, makampani ena atsopano a Tesla, BYD, NIO, Xiaopeng ndi akukonzekera kugwiritsa ntchito zipangizo kapena ma module a silicon carbide discrete.

Zipangizo za silicon carbide zosungunuka pang'ono zimagwiritsidwa ntchito makamaka pa kulumikizana kwa 5G, kulumikizana kwa magalimoto, ntchito zoteteza dziko, kutumiza deta, ndege ndi zina. Mwa kukulitsa gawo la gallium nitride epitaxial pa gawo la silicon carbide losungunuka pang'ono, wafer ya gallium nitride epitaxial yochokera ku silicon ikhoza kupangidwanso kukhala zida za microwave RF, zomwe zimagwiritsidwa ntchito kwambiri pamunda wa RF, monga ma amplifier amphamvu pakulankhulana kwa 5G ndi ma radio detectors pachitetezo cha dziko.

Kupanga zinthu zopangidwa ndi silicon carbide substrate kumaphatikizapo kupanga zida, kupanga zinthu zopangira, kukula kwa kristalo, kudula makristalo, kukonza ma wafer, kuyeretsa ndi kuyesa, ndi maulalo ena ambiri. Ponena za zipangizo zopangira, Songshan Boron industry imapereka zinthu zopangira silicon carbide pamsika, ndipo yapeza malonda ochepa. Zipangizo za semiconductor za m'badwo wachitatu zomwe zimayimiridwa ndi silicon carbide zimagwira ntchito yofunika kwambiri m'makampani amakono, chifukwa cha kufulumira kwa kulowa kwa magalimoto atsopano amphamvu ndi kugwiritsa ntchito photovoltaic, kufunikira kwa silicon carbide substrate kwatsala pang'ono kuyambitsa inflection point.
