3'īniha SiC substrate Production Dia76.2mm 4H-N

ʻO nā hiʻohiʻona nui o nā wafers mosfet silicon carbide 3 iniha penei;

ʻO Silicon Carbide (SiC) kahi mea semiconductor ākea-bandgap, i hōʻailona ʻia e ka conductivity thermal kiʻekiʻe, ka neʻe ʻana o ka electron kiʻekiʻe, a me ka ikaika o ke kahua uila breakdown kiʻekiʻe. ʻO kēia mau waiwai e hoʻolilo i nā wafers SiC i mea kūikawā i nā noi mana kiʻekiʻe, alapine kiʻekiʻe, a me nā noi wela kiʻekiʻe. ʻOi loa i ka polytype 4H-SiC, hāʻawi kona ʻano kristal i ka hana uila maikaʻi loa, e lilo ia i mea koho no nā mea uila mana.

ʻO ka wafer Silicon Carbide 4H-N 3-'īniha he wafer i hoʻohui ʻia me ka nitrogen me ka conductivity ʻano-N. Hāʻawi kēia ʻano doping i ka wafer i kahi nui o ka electron, no laila e hoʻonui ai i ka hana conductive o ka hāmeʻa. ʻO ka nui o ka wafer, ma 3 ʻīniha (ke anawaena o 76.2 mm), kahi ana i hoʻohana pinepine ʻia i ka ʻoihana semiconductor, kūpono no nā kaʻina hana like ʻole.

Hana ʻia ka wafer Silicon Carbide 4H-N 3-'īniha me ka hoʻohana ʻana i ke ʻano Physical Vapor Transport (PVT). Pili kēia kaʻina hana i ka hoʻololi ʻana i ka pauka SiC i mau kristal hoʻokahi ma nā mahana kiʻekiʻe, e hōʻoiaʻiʻo ana i ka maikaʻi o ke kristal a me ke kūlike o ka wafer. Eia kekahi, ʻo ka mānoanoa o ka wafer ma kahi o 0.35 mm, a ua hoʻopili ʻia kona ʻili i ka poli ʻana i ʻelua ʻaoʻao e hoʻokō ai i kahi pae kiʻekiʻe loa o ka pālahalaha a me ka laumania, he mea nui ia no nā kaʻina hana semiconductor ma hope.

He ākea ka laulā o ka hoʻohana ʻana o ka wafer Silicon Carbide 4H-N 3-'īniha, me nā mea uila mana kiʻekiʻe, nā mea ʻike wela kiʻekiʻe, nā mea RF, a me nā mea optoelectronic. ʻO kāna hana maikaʻi loa a me ka hilinaʻi e hiki ai i kēia mau mea ke hana paʻa ma lalo o nā kūlana koʻikoʻi, e hoʻokō ana i ke koi no nā mea semiconductor hana kiʻekiʻe i ka ʻoihana uila hou.

Hiki iā mākou ke hāʻawi i ka substrate 4H-N 3inch SiC, nā ʻano like ʻole o nā wafers waihona substrate. Hiki iā mākou ke hoʻonohonoho i ka hoʻopilikino ʻana e like me kāu mau pono. Welina mai i ka nīnau!
