I roto i te ao hangahanga haurua-ira, he mea nui te mahi a ngā taputapu tirotiro whatu aunoa (AOI) ki te whakarite i te kounga o ngā maramara. Ahakoa he iti noa te whakapai ake i tōna tika o te kitenga, ka taea te whakaputa i tētahi panonitanga nui ki te umanga katoa. Ko te turanga taputapu, hei wāhanga matua, he pānga nui ki te tika o te kitenga. I ngā tau tata nei, kua horapa te hurihanga o ngā rauemi turanga puta noa i te umanga. Ko te karāhe, me tana mahi pehi wiri tino pai, kua whakakapi haere i ngā rauemi rino maka tuku iho, ā, kua noho hei tino pai hou mō ngā taputapu tirotiro AOI. Kua piki ake tōna pai o te pehi wiri mā te 92% ki te whakaritea ki te rino maka. He aha ngā whanaketanga hangarau me ngā huringa umanga kei muri i ēnei raraunga?
Ngā whakaritenga pakari mō te wiri i roto i ngā taputapu tirotiro AOI semiconductor
Kua tae te tukanga hanga o ngā maramara haurua-ira ki te wā nano. I roto i te tukanga tirotiro AOI, ahakoa he iti rawa ngā wiri, ka taea e rātou te whakaputa i ngā rerekētanga ki ngā hua tirotiro. Ko ngā karawarawa iti, ngā āputa me ētahi atu hapa i runga i te mata o te maramara kei te taumata maikoromita, nanometa rānei. Me hopu e ngā karāhe whatu o ngā taputapu kimi ēnei taipitopito me te tino tika. Ko tētahi wiri e tukuna ana e te turanga ka meinga te karāhe kia neke, kia rūrū rānei, ka hua ake he whakaahua pōuriuri, ā, ka pā ki te tika o te mōhio ki ngā hapa.
I mua, i whakamahia whānuitia ngā rauemi rino maka i roto i ngā turanga o ngā taputapu tirotiro AOI nā te mea he kaha me te mahi tukatuka, ā, he iti te utu. Heoi, mō te pehi i te wiri, he mārama ngā ngoikoretanga o te rino maka. Kei roto i te hanganga o roto o te rino maka he maha ngā rau karāpeti, he rite ki ngā āputa iti i roto, ā, ka whakararuraru i te haere tonu o te rauemi. Ina mahi te taputapu, ka whakaputa wiri, ka whakararuraruhia rānei e te wiri taiao o waho, kāore e taea te whakaiti i te kaha wiri i roto i te rino maka engari ka whakaata tonutia, ka taupatupatuhia i waenganui i te rau karāpeti me te matihiko, ka hua ake te horapa tonu o te wiri. E whakaatu ana ngā whakamātautau e pā ana i muri i te whakaohooho o te turanga rino maka e te wiri o waho, ka roa pea te wā whakaiti wiri mō ētahi hēkona, ka pā nui ki te tika o te kitenga i tēnei wā. Hei tāpiri, he iti te modulus elastic o te rino maka. I raro i te mahi roa o te taumaha taputapu me te ahotea wiri, ka ngāwari ki te whakarerekē, ka kaha ake te tuku wiri.
Ko te mea ngaro kei muri i te pikinga 92% o te whai huatanga pehi wiri o ngā turanga karāhe
Ko te karāneti, he momo kōhatu tūturu, kua hanga he hanganga ā-roto tino matotoru, ōrite hoki i roto i ngā tukanga whenua mō ngā rau miriona tau. Ko te nuinga o te wā he mea hanga mai i ngā tioata kohuke pēnei i te kuata me te feldspar e honoa tata ana, ā, he kaha, he pumau hoki ngā hononga matū i waenganui i ngā tioata. Mā tēnei hanganga ka taea e te karāneti te pehi i te wiri. Ina tukuna te wiri ki te turanga karāneti, ka taea e ngā tioata kohuke i roto te huri tere i te kaha wiri hei kaha wera me te whakamarara. E whakaatu ana ngā rangahau he maha ngā wā teitei ake te whakamākū o te karāneti i te rino maka, ko te tikanga ka taea e ia te mimiti i te kaha wiri, ka whakaiti i te kaha me te roa o te wiri. Whai muri i ngā whakamātautau ngaio, i raro i ngā āhuatanga whakaoho wiri kotahi, ko te wā whakaiti wiri o te turanga karāneti he 8% noa iho i te rino maka, ā, kua piki ake te pai o te pehi wiri mā te 92%.
He nui hoki te pānga o te pakeketanga teitei me te modulus elasticity teitei o te karāhe. Mā te pakeketanga teitei ka iti ake te tūponotanga o te turanga ki te piko i te taumaha o ngā taputapu me ngā pānga o waho, ā, ka mau tonu te āhua tautoko pumau. Mā te modulus elasticity teitei ka taea e te turanga te hoki wawe ki tōna āhua taketake ina pāngia e te wiri, ka whakaiti i te kohikohinga o te wiri. Hei tāpiri, he tino pai te pumau o te karāhe, ā, kāore e pāngia e ngā huringa o te pāmahana taiao, ka karo i te whakawhānui me te whakahekenga o te huringa i puta mai i ngā huringa pāmahana, ā, ka whakarite kia pumau te mahi pehi wiri.
Te Huringa Ahumahi me ngā Tirohanga i Kawea mai e ngā turanga karāhe
Kua tino pai ake te tika o te kitenga o ngā taputapu tirotiro AOI me te turanga karāhe. Ka taea e ia te tautuhi pono i ngā hapa i roto i ngā maramara iti ake, ka whakaiti i te tere whakatau hē ki roto i te 1% me te whakanui ake i te tere hua o te whakaputa maramara. I taua wā, kua pai ake te pumau o ngā taputapu, ka whakaiti i te maha o ngā kati mō te tiaki i puta mai i ngā take wiri, ka roa ake te ora o ngā taputapu, ā, ka whakaiti i ngā utu whakahaere katoa.
