Ma wafer a SiC ocheperako 4inch HPSI SiC substrate Prime Production grade

Kufotokozera Kwachidule:

Mbale yopukutira ya silicon carbide yokhala ndi mbali ziwiri yokhala ndi insulation ya mainchesi 4 imagwiritsidwa ntchito kwambiri pakulankhulana kwa 5G ndi madera ena, ndi ubwino wokweza kuchuluka kwa ma radio frequency, kuzindikira mtunda wautali kwambiri, kupewa kusokonezedwa, kutumiza zambiri mwachangu komanso mwachangu komanso ntchito zina, ndipo imaonedwa ngati gawo labwino kwambiri lopangira zida zamagetsi za microwave.

Silicon carbide (SiC) ndi chinthu chopangidwa ndi zinthu za semiconductor chomwe chimapangidwa ndi zinthu za kaboni ndi silicon, ndipo ndi chimodzi mwa zipangizo zabwino kwambiri zopangira zida zotentha kwambiri, zamafupipafupi, zamphamvu kwambiri komanso zama voltage apamwamba. Poyerekeza ndi zinthu zachikhalidwe za silicon (Si), m'lifupi mwa band yoletsedwa ya silicon carbide ndi katatu kuposa silicon; kutentha kwa conductivity ndi nthawi 4-5 kuposa silicon; voltage yosweka ndi nthawi 8-10 kuposa silicon; ndipo kuchuluka kwa ma electron saturation drift ndi nthawi 2-3 kuposa silicon, zomwe zimakwaniritsa zosowa zamakampani amakono zamphamvu kwambiri, zama voltage apamwamba, komanso zamafupipafupi, ndipo imagwiritsidwa ntchito kwambiri popanga zida zamagetsi zothamanga kwambiri, zamafupipafupi, zamphamvu kwambiri komanso zotulutsa kuwala, ndipo madera ake ogwiritsira ntchito akuphatikizapo gridi yanzeru, magalimoto atsopano amphamvu, mphamvu ya mphepo ya photovoltaic, kulumikizana kwa 5G, ndi zina zotero. Pankhani ya zida zamagetsi, ma diode a silicon carbide ndi ma MOSFET ayamba kugwiritsidwa ntchito pamalonda.

Ubwino wa ma wafer a SiC/SiC substrate

Kukana kutentha kwambiri. M'lifupi mwa silicon carbide yoletsedwa ndi kuwirikiza kawiri kapena katatu kuposa silicon, kotero ma elekitironi satha kulumpha kutentha kwambiri ndipo amatha kupirira kutentha kwakukulu, ndipo mphamvu ya kutentha ya silicon carbide ndi kuwirikiza kanayi kapena kasanu kuposa silicon, zomwe zimapangitsa kuti kutentha kuchotsedwe mosavuta kuchokera pa chipangizocho ndikulola kutentha kwakukulu kogwirira ntchito. Makhalidwe a kutentha kwambiri amatha kuwonjezera mphamvu yamagetsi, pomwe amachepetsa zofunikira pamakina ochotsera kutentha, zomwe zimapangitsa kuti terminal ikhale yopepuka komanso yaying'ono.

Kukana kwa mphamvu yamagetsi yapamwamba. Mphamvu ya silicon carbide yophwanyika ndi yowirikiza ka 10 kuposa silicon, zomwe zimapangitsa kuti ikhale yolimba pamagetsi amphamvu kwambiri, zomwe zimapangitsa kuti ikhale yoyenera kwambiri pazida zamagetsi amphamvu kwambiri.

Kukana kwa ma frequency apamwamba. Silicon carbide ili ndi kuchuluka kwa ma elekitironi ochulukirapo kawiri kuposa silicon, zomwe zimapangitsa kuti zida zake zisagwire ntchito bwino chifukwa cha kutsekeka kwa magetsi, zomwe zimathandiza kuti chipangizocho chizisinthasintha pafupipafupi, kuti chipangizocho chizigwira ntchito pang'ono.

Kutaya mphamvu kochepa. Silicon carbide ili ndi mphamvu yochepa kwambiri poyerekeza ndi zinthu za silicon, kutayika kochepa kwa conduction; nthawi yomweyo, bandwidth yayikulu ya silicon carbide imachepetsa kwambiri kutayikira kwa mphamvu, kutayika kwa mphamvu; kuphatikiza apo, zida za silicon carbide zomwe zimazimitsidwa sizipezeka muzochitika za current drag, kutayika kochepa kwa switching.
