I tenei wa, ka taea e to taatau kamupene te tuku i nga waahanga iti o te 8inchN momo SiC wafers, mena kei a koe nga hiahia tauira, tena koa waea mai ki a au.Kei a matou etahi tauira angiangi kua reri ki te tuku.
I roto i te mara o nga rauemi semiconductor, kua hanga e te kamupene he pakaruhanga nui i roto i te rangahau me te whanaketanga o nga tioata SiC rahi nui.Ma te whakamahi i ona ake tioata uri i muri i nga rauna maha o te whakanui i te diameter, kua pai te tipu o te kamupene 8-inihi momo N-momo kiripiri SiC, e whakaoti rapanga uaua penei i te waahi pāmahana pahekeheke, te pakaru o te karaihe me te wahanga hau te tohatoha rauemi mata i roto i te tipu o te tipu. Ko nga kiripiri SIC 8-inihi, me te whakatere i te tipu o nga kiripiri SIC rahi nui me te hangarau tukatuka motuhake me te whakahaere.Ka tino whakanui i te whakataetae matua o te kamupene i roto i te SiC kotahi ahumahi tïpako karaihe.I te wa ano, te kamupene kaha whakatairanga i te haaputuputuraa o te hangarau me te tukanga o te rahi nui silicon carbide tïpako faaineineraa raina whakamātautau, whakapakari i te whakawhitinga hangarau me te mahi tahi ahumahi i roto i te whakarunga, me te whakararo mara, me te mahi tahi ki te kiritaki ki te huri tonu mahi hua, me te tahi. ka whakatairanga i te tere o te tono ahumahi o nga rauemi carbide silicon.
