Nā Kiʻi Kūʻai ʻo Silicon Carbide|SiC Wafers

ʻO ka wehewehe pōkole:

ʻO WeiTai Energy Technology Co., Ltd. kahi mea hoʻolako alakaʻi kūikawā i ka wafer a me nā mea hoʻohana semiconductor holomua.Hoʻolaʻa mākou i ka hāʻawi ʻana i nā huahana kiʻekiʻe, hilinaʻi, a me nā mea hou i ka hana semiconductor, ʻoihana photovoltaic a me nā ʻoihana ʻē aʻe e pili ana.

Loaʻa i kā mākou laina huahana nā huahana graphite i uhi ʻia ʻo SiC/TaC a me nā huahana seramika, e hoʻopuni ana i nā mea like ʻole e like me ka silicon carbide, silicon nitride, a me ka alumini oxide a me nā mea ʻē aʻe.

I kēia manawa, ʻo mākou wale nō ka mea hana e hāʻawi i ka maʻemaʻe 99.9999% SiC coating a me 99.9% recrystallized silicon carbide.ʻO ka lōʻihi o ka uhi ʻana o SiC hiki iā mākou ke hana 2640mm.

E hoʻouna i ka leka uila iā mākou

Huahana Huahana

ʻO Silicon carbide (SiC) hoʻokahi kristal mea i loaʻa i kahi ākea ākea nui (~ Si 3 mau manawa), kiʻekiʻe thermal conductivity (~ Si 3.3 mau manawa a i ʻole GaAs 10 manawa), kiʻekiʻe electron saturation migration rate (~ Si 2.5 mau manawa), kiʻekiʻe breakdown uila. kahua (~ Si 10 manawa a i ʻole GaAs 5 manawa) a me nā hiʻohiʻona ʻē aʻe.

Loaʻa i nā mea SiC nā pono kūpono ʻole i ke kahua o ka wela kiʻekiʻe, ke kaomi kiʻekiʻe, ke alapine kiʻekiʻe, nā mana uila kiʻekiʻe a me nā noi kūlohelohe e like me ka aerospace, ka pūʻali koa, ka ikehu nuklea, a me nā mea ʻē aʻe. nā noi, a ke lilo nei i mea nui o nā semiconductors mana.
