I roto i te mara o te hanga haurua-ira, hei taputapu matua e whakatau ana i te tika o te tukanga hanga maramara, he mea tino nui te pumau o te taiao o roto o te mīhini whakaahua-ira. Mai i te whakaohooho o te pūtake mārama ultraviolet tino nui ki te whakahaere o te tūāpapa nekehanga tika nanoscale, kāore e taea te peka ke i roto i ia hononga. Ko ngā turanga karāneti, me te raupapa o ngā āhuatanga ahurei, e whakaatu ana i ngā painga kore e rite ki te whakarite i te mahi pumau o ngā mīhini whakaahua-ira me te whakarei ake i te tika o te whakaahua-ira.
He mahi tino pai mō te tiaki hikohiko
Kī tonu te roto o te mīhini whakaahua-ipurangi i tētahi taiao hikohiko matatini. Ko te whakararuraru hikohiko (EMI) e puta mai ana i ngā wāhanga pēnei i ngā pūtake mārama ultraviolet tino kaha, ngā motuka taraiwa, me ngā pūtake hiko auau-tiketike, ki te kore e whakahaeretia pai, ka pā kino ki te mahi a ngā wāhanga hiko tino tika me ngā pūnaha whatu i roto i te taputapu. Hei tauira, ka puta pea i te whakararuraru he rerekētanga iti i roto i ngā tauira whakaahua-ipurangi. I roto i ngā tukanga hanga matatau, he nui tēnei hei arahi i ngā hononga transistor hē i runga i te maramara, ka whakaiti nui i te hua o te maramara.
He rauemi kore-whakarewa te karāneti, ā, kāore e kawe hiko i a ia anō. Kāore he āhuatanga whakapūnga hikohiko e puta mai ana i te nekehanga o ngā irahiko kore utu i roto, pērā i ngā rauemi whakarewa. Nā tēnei āhuatanga ka waiho hei tinana ārai hikohiko tūturu, ka taea te aukati i te ara tuku o te pokanoa hikohiko ā-roto. Ina horapa te papa aukume tauutuutu i hangaia e te pūtake pokanoa hikohiko o waho ki te turanga karāneti, nā te mea he kore-aukume te karāneti, ā, kāore e taea te aukume, he uaua ki te uru ki te papa aukume tauutuutu, ā, mā reira ka tiakina ngā wāhanga matua o te mīhini whakaahua-whakaahua kua tāutahia ki te turanga, pērā i ngā pūoko tika me ngā taputapu whakatikatika arotahi whatu, mai i te awe o te pokanoa hikohiko, ā, ka whakarite i te tika o te whakawhiti tauira i te wā o te tukanga whakaahua-whakaahua.
He hototahitanga tino pai ki te korehau
Nā te mea he ngāwari te mimiti o te mārama ultraviolet tino kaha (EUV) e ngā matū katoa, tae atu ki te hau, me mahi ngā mīhini tuhi EUV i roto i te taiao korehau. I tēnei wā, ka tino hira te hototahitanga o ngā wāhanga taputapu ki te taiao korehau. I roto i te korehau, ka memeha pea ngā rauemi, ka mimiti, ka tuku hau. Ehara i te mea ka mimiti noa te hau i te mārama EUV, ka whakaiti i te kaha me te pai o te tuku o te mārama, engari ka poke pea i ngā karāhe whatu. Hei tauira, ka taea e te mamaoa wai te whakawairakau i ngā karāhe, ā, ka taea e ngā warowaihā te whakatakoto i ngā paparanga waro ki runga i ngā karāhe, ka pā kino ki te kounga o te tuhi.
He pumau ngā āhuatanga matū o te karāneti, ā, kāore e tino tukuna te hau i roto i te taiao korehau. E ai ki ngā whakamātautau ngaio, i roto i te taiao korehau mīhini whakaahua whakaahua whaihanga (pēnei i te taiao korehau tino ma kei reira te pūnaha whatu whakamārama me te pūnaha whatu whakaahua i roto i te rūma matua, e hiahia ana kia H₂O < 10⁻⁵ Pa, CₓHᵧ < 10⁻⁷ Pa), he tino iti te tere o te putanga hau o te turanga karāneti, he iti iho i ērā o ētahi atu rauemi pēnei i ngā konganuku. Mā tēnei ka taea e te roto o te mīhini whakaahua whakaahua te pupuri i te taumata korehau teitei me te ma mō te wā roa, e whakarite ana i te tuku teitei o te mārama EUV i te wā e tukuna ana me te taiao whakamahinga tino ma mō ngā karāhe whatu, e whakaroa ana i te roanga o te mahi a te pūnaha whatu, me te whakarei ake i te mahi whānui o te mīhini whakaahua whakaahua.
He kaha te ātete wiri me te pumau wera
I te wā o te tukanga whakaahua-ipurangi, ko te tika i te taumata nanometa e hiahia ana kia kaua te mīhini whakaahua-ipurangi e wiri, e whakarerekē rānei i te wera. Ko ngā wiri taiao e puta mai ana i te whakahaerenga o ētahi atu taputapu me te nekehanga o ngā kaimahi i roto i te awheawhe, me te wera e puta mai ana i te mīhini whakaahua-ipurangi i te wā e whakahaerehia ana, ka pā kino ki te tika o te whakaahua-ipurangi. He matotoru te karāhe, he mārō te kakano, ā, he tino ātete ki te wiri. He kikī te hanganga tioata kohuke o roto, ka taea te whakaiti i te kaha wiri me te pehi tere i te horapa o te wiri. E whakaatu ana ngā raraunga whakamātautau i raro i te pūtake wiri kotahi, ka taea e te turanga karāhe te whakaiti i te kaha wiri neke atu i te 90% i roto i te 0.5 hēkona. Ki te whakatauritea ki te turanga whakarewa, ka taea e ia te whakahoki wawe i te taputapu ki te pumau, me te whakarite i te tūranga whanaunga tika i waenga i te arotahi whakaahua-ipurangi me te papa, me te karo i te pōuri o te tauira, te hē rānei o te tūnga i puta mai i te wiri.
I taua wā tonu, he tino iti te tauwehenga o te whakawhanuitanga wera o te karāhe, tata ki te (4-8) ×10⁻⁶/℃, he iti iho i tērā o ngā rauemi whakarewa. I te wā e whakahaerehia ana te mīhini whakaahua-ipurangi, ahakoa te rerekētanga o te pāmahana o roto nā ngā āhuatanga pēnei i te whakaputanga wera mai i te pūtake mārama me te waku mai i ngā wāhanga miihini, ka taea e te turanga karāhe te pupuri i te pumau o ngā āhuatanga, ā, e kore e pāngia e te rerekētanga nui nā te whakawhanuitanga me te whakahekenga wera. Ka whakaratohia he tautoko pumau me te pono mō te pūnaha whatu me te tūāpapa nekehanga tika, me te pupuri i te ōritetanga o te tika o te whakaahua-ipurangi.
