SiC substrate Dia200mm 4H-N ndi HPSI Silicon carbide

4H-N ndi HPSI ndi mtundu wa polytype wa silicon carbide (SiC), yokhala ndi kapangidwe ka kristalo kokhala ndi mayunitsi a hexagonal opangidwa ndi maatomu anayi a kaboni ndi maatomu anayi a silicon. Kapangidwe kameneka kamapereka zinthuzo ndi kuyenda bwino kwa ma elekitironi ndi mphamvu yamagetsi yosweka. Pakati pa mitundu yonse ya SiC, 4H-N ndi HPSI zimagwiritsidwa ntchito kwambiri pamagetsi amphamvu chifukwa cha kuyenda kwake koyenera kwa ma elekitironi ndi mabowo komanso kutentha kwambiri.

Kutuluka kwa ma substrate a 8inch SiC kukuyimira kupita patsogolo kwakukulu kwa makampani opanga ma semiconductor amphamvu. Zipangizo zachikhalidwe za semiconductor zochokera ku silicon zimakumana ndi kuchepa kwakukulu kwa magwiridwe antchito pansi pa mikhalidwe yovuta kwambiri monga kutentha kwambiri ndi ma voltage ambiri, pomwe ma substrate a SiC amatha kusunga magwiridwe antchito awo abwino kwambiri. Poyerekeza ndi ma substrate ang'onoang'ono, ma substrate a 8inch SiC amapereka malo akuluakulu opangira chinthu chimodzi, zomwe zikutanthauza kuti kupanga bwino kwambiri komanso ndalama zochepa, zomwe ndizofunikira kwambiri poyendetsa njira yogulitsira ukadaulo wa SiC.

Ukadaulo wa kukula kwa ma substrate a 8inch silicon carbide (SiC) umafuna kulondola kwambiri komanso kuyera. Ubwino wa substrate umakhudza mwachindunji magwiridwe antchito a zida zina, kotero opanga ayenera kugwiritsa ntchito ukadaulo wapamwamba kuti atsimikizire ungwiro wa kristalo ndi kuchuluka kochepa kwa zolakwika za ma substrate. Izi nthawi zambiri zimaphatikizapo njira zovuta zosungira nthunzi ya mankhwala (CVD) ndi njira zolondola zokulira ndi kudula makristalo. Ma substrate a 4H-N ndi HPSI SiC amagwiritsidwa ntchito kwambiri m'magawo amagetsi amphamvu, monga ma converter amphamvu amphamvu kwambiri, ma traction inverters amagalimoto amagetsi, ndi makina amagetsi obwezerezedwanso.

Tikhoza kupereka 4H-N 8inch SiC substrate, mitundu yosiyanasiyana ya ma wafers a substrate stock. Tikhozanso kukonza zosintha malinga ndi zosowa zanu. Takulandirani mafunso!
