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.
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.
