pekapeka karaka silicon
Hua taipitopito
He teitei te kiato, he maeneene te mata. Te wera nui me te kaha pehanga me te kaha o te nekehanga, kaore he rereketanga. Te aukati ki te tarai, he pai te aukati i te ru o te waiariki, ehara i te ngaua ngawari. He pai te aukati waikura, ka whakamahia hei tahu ki te haurangi whakawaikaha o te hau me te whakaiti i te haurangi. Ka taea te whakapai ake i te whakamahinga o te oumu me te tere whakaora penapena.
Ka whakataurite ki te sic kua honoa me te nitride honoa, he pai ake te mahi mo te wa roa mo te urupare-kaari. Ko te kaha o te nekehanga o te sic tauhohenga-whanonga he neke atu i te rua nga wa o te sic whakahounga me te 50% teitei ake i te nitride herea sic
