Hoʻolauna ʻo vet-china i kahi Waʻa Wafer Contiguous hou loa i hana ʻia no ka hanauna hou o ka hana semiconductor. Hāʻawi kēia waʻa i hoʻolālā pono ʻia i ka pololei kūlike ʻole i ka lawelawe ʻana i nā wafer, e hōʻoiaʻiʻo ana i nā hana maʻalahi a me ka hoʻemi nui ʻana i ka pilikia o ka hōʻino ʻia i ka wā o ka hana ʻana.
Kūkulu ʻia me nā mea kiʻekiʻe, ka Contiguous Wafer Boat e kaena nei i ke kūpaʻa wela maikaʻi loa a me ke kūpaʻa kemika koʻikoʻi, e kūpono ana no nā wahi wela kiʻekiʻe a me nā kemika ʻino. ʻO kāna hoʻolālā hou e hōʻoiaʻiʻo ana ua paʻa pono nā wafers a ua kūlike pono, e hoʻonui ana i ka throughput a hoʻonui i ka pono hana.
Ua hana ʻia kēia waʻa wafer ʻoi loa e hoʻokō i nā pono koi o nā lole semiconductor hou, e kākoʻo ana i nā nui wafer like ʻole a me nā hoʻonohonoho. Ma ka hoʻohui ʻana i ka Contiguous Wafer Boat mai vet-china i kāu laina hana, hiki iā ʻoe ke manaʻo i ka hana i hoʻonui ʻia, ka hoʻemi ʻana i ka manawa downtime, a me ka hoʻonui ʻana i nā helu hua.
E ʻike i ka ʻokoʻa me ka hoʻokō ʻana o vet-china i ka maikaʻi a me ka hana hou, e hāʻawi ana i nā huahana e hoʻokuke i nā palena o ka hana semiconductor. E koho i ka Contiguous Wafer Boat a hoʻokiʻekiʻe i kāu mau hiki ke hana wafer i nā kiʻekiʻe hou.
Nā waiwai o ka carbide silicon i hoʻopili hou ʻia
ʻO ka silicon carbide i hoʻopili hou ʻia (R-SiC) kahi mea hana kiʻekiʻe me ka paʻakikī ʻelua wale nō i ka daimana, i hoʻokumu ʻia ma kahi mahana kiʻekiʻe ma luna o 2000 ℃. Mālama ia i nā waiwai maikaʻi loa o SiC, e like me ka ikaika wela kiʻekiʻe, ke kūpaʻa ikaika i ka pala, ke kūpaʻa oxidation maikaʻi loa, ke kūpaʻa haʻalulu wela maikaʻi a pēlā aku.
● Nā waiwai mechanical maikaʻi loa. ʻOi aku ka ikaika a me ke kūpaʻa o ka silicon carbide i hoʻopili hou ʻia ma mua o ke kalapona fiber, kū'ē i ka hopena kiʻekiʻe, hiki ke pāʻani i kahi hana maikaʻi i nā wahi mahana koʻikoʻi, hiki ke pāʻani i kahi hana counterbalance maikaʻi aʻe i nā kūlana like ʻole. Eia kekahi, he maʻalahi hoʻi kona a ʻaʻole maʻalahi e hōʻino ʻia e ke kīkoʻo ʻana a me ke kūlou ʻana, kahi e hoʻomaikaʻi nui ai i kāna hana.
● Ke kūpaʻa kiʻekiʻe i ka pala. Loaʻa i ka silicon carbide i hoʻopili hou ʻia ke kūpaʻa kiʻekiʻe i ka pala i nā ʻano media like ʻole, hiki ke pale i ka ʻino ʻana o nā ʻano media corrosive like ʻole, hiki ke mālama i kona mau waiwai mechanical no ka manawa lōʻihi, he pipili ikaika, no laila he ola lawelawe lōʻihi. Eia kekahi, he kūpaʻa maikaʻi hoʻi kona, hiki ke hoʻololi i kahi ākea o nā loli mahana, hoʻomaikaʻi i kāna hopena noi.
● ʻAʻole emi ka sintering. No ka mea, ʻaʻole emi ka hana sintering, ʻaʻohe koʻikoʻi koena e hoʻoulu ai i ka deformation a i ʻole ka haki ʻana o ka huahana, a hiki ke hoʻomākaukau ʻia nā ʻāpana me nā ʻano paʻakikī a me ke kiko kiʻekiʻe.
