Hāʻawi ʻo Semicera i nā ʻāpana tantalum carbide (TaC) kūikawā no nā ʻāpana like ʻole a me nā mea lawe.ʻO ke kaʻina hana hoʻopili alakaʻi Semicera e hiki ai i ka tantalum carbide (TaC) ke hoʻokō i ka maʻemaʻe kiʻekiʻe, ke kūpaʻa wela kiʻekiʻe a me ka hoʻomanawanui kiʻekiʻe, e hoʻomaikaʻi i ka maikaʻi o ka huahana o nā kristal SIC / GAN a me nā papa EPI (Kāpena ʻo TaC i uhi ʻia i ka graphite), a hoʻonui i ke ola o nā ʻāpana reactor koʻikoʻi.ʻO ka hoʻohana ʻana i ka tantalum carbide TaC coating ka mea e hoʻoponopono ai i ka pilikia lihi a hoʻomaikaʻi i ka maikaʻi o ka ulu ʻana o ke aniani, a ua hoʻopau ʻo Semicera i ka ʻenehana tantalum carbide coating (CVD), a hiki i ka pae kiʻekiʻe honua.
ʻO Silicon carbide (SiC) kahi mea koʻikoʻi i ke kolu o ka hanauna o nā semiconductor, akā ʻo ka nui o ka hoʻoulu ʻana he kumu palena ia no ka ulu ʻana o ka ʻoihana.Ma hope o ka hoʻāʻo nui ʻana ma nā hale hana o Semicera, ua ʻike ʻia ʻaʻole i pau ka maʻemaʻe a me ka like ʻole o ka TaC i kāpī ʻia a sintered.Ma ka hoʻohālikelike ʻana, ʻo ke kaʻina hana CVD e hōʻoia i ka pae maʻemaʻe o 5 PPM a me ke ʻano like ʻole.ʻO ka hoʻohana ʻana i ka CVD TaC e hoʻomaikaʻi nui i ka nui o ka hua o nā wafers carbide silicon.Aloha mākou i nā kūkākūkāNā apo lima ʻāpana ʻekolu ʻāpana ʻo TaC e hoemi hou aku i na koina o na wafers SiC.
Ma hope o nā makahiki o ka hoʻomohala ʻana, ua lanakila ʻo Semicera i ka ʻenehana oCVD TaCme ka hooikaika pu ana o ka oihana R&D.He mea maʻalahi nā hemahema i ka ulu ʻana o nā wafers SiC, akā ma hope o ka hoʻohana ʻanaTaC, nui ka ʻokoʻa.Ma lalo iho nei ka hoʻohālikelike ʻana o nā wafers me ka TaC a me ka ʻole o TaC, a me nā ʻāpana ʻo Simicera 'no ka ulu aniani hoʻokahi.
me ka TaC ole
Ma hope o ka hoʻohana ʻana iā TaC (ʻākau)
Eia kekahi, ʻo SemiceraNā huahana i uhi ʻia e TaChōʻike i kahi ola lawelawe lōʻihi a ʻoi aku ka nui o ke kūpaʻa wela kiʻekiʻe i hoʻohālikelike ʻia meʻO nā uhi SiC.Ua hōʻike ʻia nā ana Laboratory i kā mākouʻO nā pale TaChiki ke hana mau i ka wela a hiki i 2300 degere Celsius no nā manawa lōʻihi.Aia ma lalo kekahi mau laʻana o kā mākou mau laʻana:
