6 mu Silicon Carbide 4H-SiC Semi-Insulating Ingot, Chithunzi Chodziwika Bwino

Kufotokozera Kwachidule:

Silicon Carbide (SiC) ikusinthiratu makampani opanga ma semiconductor, makamaka pakugwiritsa ntchito mphamvu zambiri, ma frequency apamwamba, komanso ma radiation osagwira ntchito. Ingot ya mainchesi 6 ya 4H-SiC semi-insulating, yoperekedwa mu dummy grade, ndi chinthu chofunikira kwambiri pakupanga ma prototyping, kafukufuku, ndi njira zowerengera. Ndi bandgap yayikulu, kutentha kwabwino kwambiri, komanso kulimba kwa makina, ingot iyi imagwira ntchito ngati njira yotsika mtengo yoyesera ndikuwongolera njira popanda kuwononga khalidwe lofunikira pakukula kwapamwamba. Chogulitsachi chimagwira ntchito zosiyanasiyana, kuphatikiza zamagetsi zamagetsi, zida zama radio-frequency (RF), ndi ma optoelectronics, zomwe zimapangitsa kuti ikhale chida chofunikira kwambiri m'makampani ndi mabungwe ofufuza.
