Ko Semicera's Silicon On Insulator (SOI) Wafer kei mua i te mahi hou semiconductor, e tuku ana i te whakawehe hiko me te mahi waiariki pai ake. Ko te hanganga SOI, he paparanga hiako angiangi i runga i te tïpako whakaraerae, he tino painga mo nga taputapu hiko tino mahi.
I hangaia a tatou angiangi SOI ki te whakaiti i te kaha parapara me te rerenga rerenga, he mea nui mo te whakawhanake iahiko whakauru-tere me te iti-hiko. Ko tenei hangarau matatau ka whakarite kia pai ake te mahi o nga taputapu, me te pai ake o te tere me te whakaiti i te kohi hiko, he mea nui mo te hikohiko hou.
Ko nga mahi whakangao matatau e mahia ana e Semicera e whakamana ana i te hanga o nga angiangi SOI me te tino rite me te riterite. He mea nui tenei kounga mo nga tono i roto i te waea, te miihini, me te hikohiko kaihoko, e hiahiatia ana nga waahanga pono me te tino mahi.
I tua atu i o raatau painga hiko, ka tukuna e te Semicera's SOI wafers te whakamaarama waiariki pai ake, te whakarei ake i te tohanga wera me te pumau i roto i nga taputapu teitei me te hiko teitei. He mea tino nui tenei ahuatanga i roto i nga tono e uru ana ki te whakaputa wera nui me te hiahia ki te whakahaere waiariki whai hua.
Ma te kowhiri i a Semicera's Silicon On Insulator Wafer, ka haumi koe ki tetahi hua e tautoko ana i te ahu whakamua o nga hangarau hou. Ko ta matou piripono ki te kounga me te auahatanga ka whakarite kia tutuki a matou angiangi SOI ki nga tono uaua o te umanga semiconductor o enei ra, e whakarato ana i te turanga mo nga taputapu hiko o muri mai.
