I roto i te tukanga o te ahumahi haurua-irahiko e anga atu ana ki ngā tukanga hanga nanoscale, ko te tapahi wafer, hei hononga matua i roto i te hanga maramara, he tino kaha ngā whakaritenga mō te pumau o ngā taputapu. Ko te turanga karāhe, me tōna ātete wiri me te pumau wera, kua noho hei wāhanga matua o ngā taputapu tapahi wafer, e whakarato ana i te taurangi pono mō te whakatutuki i te tukatuka wafer tino tika me te tino whai hua.
Ngā āhuatanga whakamākū teitei me te ārai-wiri: Te tiaki i te tika tapahi taumata-nano
I te wā e whakamahia ana te taputapu tapahi wafer, ka pā nui te hurihanga tere o te miro, te wiri auau teitei o te taputapu tapahi, me te wiri taiao e puta mai ana i ngā taputapu e karapoti ana ki te tika o te tapahi. He iti te mahi whakaiti o ngā turanga whakarewa tuku iho, ka uaua ki te whakaiti tere i ngā wiri, ka hua ake te wiri taumata-micron o ngā taputapu tapahi, ā, ka puta tika ngā hapa pēnei i ngā taha pakaru me ngā kapiti i runga i ngā wafer. Nā ngā āhuatanga whakaiti teitei o te turanga karāhe i whakatau i tēnei raruraru.
He hononga tata ngā tioata kohuke o roto o te karāneti, ka hanga he hanganga maori mō te tohatoha pūngao. Ina tukuna te wiri ki te turanga, ka taea e tōna hanganga iti o roto te huri tere i te pūngao wiri hei pūngao wera, ka tutuki ai te whakaiti wiri whai hua. E whakaatu ana ngā raraunga whakamātautau i raro i te taiao wiri kotahi, ka taea e te turanga karāneti te whakaiti i te kaha wiri neke atu i te 90% i roto i te 0.5 hēkona, ko te turanga whakarewa ia e 3 ki te 5 hēkona. Mā tēnei mahi whakaiti tino pai ka noho pumau te taputapu tapahi i te wā o te tukanga tapahi nano, ka whakarite kia maeneene te taha o te tapahi wafer me te whakaiti i te tere maramara. Hei tauira, i roto i te tukanga tapahi wafer 5nm, ka taea e ngā taputapu he turanga karāneti te whakahaere i te rahi maramara i roto i te 10μm, neke atu i te 40% teitei ake i ngā taputapu he turanga whakarewa.
Te tauwehenga tino iti o te whakawhānui wera: Ātete ki te awe o ngā huringa pāmahana
I te wā e tapahia ana te anga, ka taea e te wera e puta mai ana i te waku o ngā taputapu tapahi, te marara o te wera mai i te mahi roa o ngā taputapu, me ngā huringa o te pāmahana o te taiao awheawhe te whakararu i te āhua wera o ngā wāhanga taputapu. He teitei te tauwehenga whānui wera o ngā rauemi whakarewa (tata ki te 12×10⁻⁶/℃). Ina piki te pāmahana mā te 5℃, ka taea e te turanga whakarewa 1 mita te roa te whakararu i te āhua o te 60μm, ka neke te tūranga tapahi, ā, ka pā kino ki te tika o te tapahi.
Ko te tauwehenga o te whakawhānui wera o te turanga karāhe he (4-8) ×10⁻⁶/℃ anake, he iti iho i te kotahi-tuatoru o te rauemi whakarewa. I raro i te huringa pāmahana kotahi, tata kore e taea te wareware i tōna huringa āhua. E whakaatu ana ngā raraunga ine o tētahi umanga hanga haurua-ira i roto i te mahi tapahi wafer kaha-teitei e 8-hāora tonu, ina rerekē te pāmahana taiao mā te 10℃, ko te rerekētanga tūranga tapahi o te taputapu me te turanga karāhe he iti iho i te 20μm, ko te taputapu me te turanga whakarewa neke atu i te 60μm. Mā tēnei mahi wera pumau ka noho tika tonu te tūranga whanaunga i waenga i te taputapu tapahi me te wafer. Ahakoa i raro i te mahi tonu mō te wā roa, i raro rānei i ngā huringa nui o te pāmahana taiao, ka taea te pupuri i te ōritetanga o te tika o te tapahi.
Te pakari me te ātete ki te kakahu: Me whakarite kia pumau te mahi a te taputapu mō te wā roa
Haunga ngā painga o te ātete ki te wiri me te pumau o te wera, ko te pakari me te ātete ki te kakahu o te turanga karāhe ka whakarei ake i te pono o te taputapu tapahi wafer. Ko te pakeke o te karāhe he 6 ki te 7 i runga i te tauine Mohs, ā, ko te kaha pēhi he neke atu i te 120MPa. Ka taea e ia te tu atu i te pēhanga nui me te kaha pānga i te wā o te tukanga tapahi, ā, kāore e ngāwari ki te whakarerekē. I taua wā, ko tōna hanganga matotoru e whakarato ana i te ātete kakahu pai rawa atu. Ahakoa i roto i ngā mahi tapahi auau, kāore te mata o te turanga e ngāwari ki te kakahu, kia mau tonu ai te mahi tino tika o te taputapu mō te wā roa.
I roto i ngā mahi whaihua, he maha ngā umanga hanga wafer kua tino whakapai ake i te hua hua me te pai o te whakaputa mā te whakamahi i ngā taputapu tapahi me ngā turanga karāhe. E whakaatu ana ngā raraunga mai i tētahi whare whakarewa matua o te ao, whai muri i te whakaurunga o ngā taputapu turanga karāhe, kua piki ake te hua tapahi wafer mai i te 88% ki te neke atu i te 95%, kua whakaroahia te huringa tiaki taputapu e toru ngā wā, ā, he pai te whakaiti i ngā utu whakaputa me te whakarei ake i te whakataetae mākete.
Hei whakamutunga, ko te turanga karāneti, me tōna ātete wiri pai, te pumau wera, te pakari teitei me te ātete kakahu, e whakarato ana i te taurangi mahi whānui mō ngā taputapu tapahi wafer. I te whanaketanga o te hangarau haurua-ira ki te tika teitei ake, ka nui ake te mahi a ngā turanga karāneti i roto i te mara o te hanga wafer, e whakatairanga ana i te whanaketanga auaha tonu o te umanga haurua-ira.
