Ngā Wāhanga Karāhe Tika i roto i ngā Pūnaha Whatu: Ngā Whakamahinga me ngā Wero Hanga

Ko te karāhe whatu te pou tuarā o te hangarau whakaahua o ēnei rā. Mai i te whakawhitiwhiti kōrero ki te tiaki, kei te piki haere te kaha o ngā whakaritenga mō ēnei wāhanga.

I roto i ngā pūnaha taiaho mana-nui, me tu atu ngā wāhanga whatu ki ngā kiato kaha nui. Mā tētahi hapa iti rawa, mā tētahi poke rānei i roto i te karāhe ka taea te kino i puta mai i te taiaho, ka whakararu i te pūnaha katoa. Ko te arotahi hangahanga i konei ko te whakakore i ngā kino o raro i te mata me te whakarite kia tino ōrite te hihi hei ārai i te hē o te hihi.

I te mea ka tipu haere te rahi o ngā karu tirohanga ātea me ngā taputapu tirotiro mamao (kua neke atu i te 4 mita inaianei), ka kaha ake te hiahia mō te māmā me te tika o te mata. Me mau tonu te āhua o ngā wāhanga whatu mō te ātea i roto i ngā taiao wera nui, me te hiahia ki ngā rauemi he iti rawa ngā tauwehenga whānui wera.

I roto i te umanga haurua-ira, ka whakawhirinaki ngā pūnaha whakaata EUV ki ngā whakaata whakaata me te taratara o te mata e whakahaeretia ana ki raro iho i te 0.1 nm (RMS). Ahakoa ngā puku taumata-atomika ka taea te marara i te mārama me te whakakino i te taumira o te maramara. Koinei te tihi o te hanga karaihe whatu.

Te Wero Hanga: Te Taumahatanga, Te Papatahi, me te Māeneene

1. Te Whakahaere i te Taumahatanga ā-Roto

• Te Wero: He maha ngā wā ka puta he ahotea iti i te mahi miihini i te karāhe mārō, pakarukaru.
• Tā Mātou Huarahi: Ka whakamahia e mātou ngā tukanga whakamahana matatau me ngā tikanga hanga iti te pakaru. Mā te whakahaere pūmau i ngā tere whakamatao me te whakamahi i ngā rautaki miihini whakaiti ahotea, ka whakarite mātou kia noho pūmau, kia kore e pāngia te hanganga o roto o te karāhe.

2. Te Whakatutuki i te Papatahi Tino-Tiketike (Te Tika o te Auautanga Iti)

• Te Wero: Ka waiho pea e te huri tuku iho he pōturi, he hapa rānei e whakaiti ana i te tika o te mata o te ngaru.
• Tā Mātou Huarahi: Ka whakamahia e mātou te mata whatu whakahaere-rorohiko (CCOS) tino tika. Mā tēnei ka taea e mātou te whakatika i ngā hapa auau-iti (ngā rerekētanga āhua) kia eke ki ngā uara tihi-ki-te-awaawa (PV) he iti iho i te 1 nm, kia mau tonu ai te tūnga tika o te ara whatu.

3. Te Pākari o te Mata (Te Maeneene Auau Teitei)

• Te Wero: Ko te tango i te "kohu" me ngā karawarawa moroiti i mahue mai i te huri me huri i te mata mai i te tango rauemi ki te whakamāeneene.
• Tā Mātou Huarahi: Ka whakamahia e mātou ngā hangarau whakakanapa matatau, tae atu ki te whakaotinga āwhina aukume. Mā tēnei tikanga ka taea te tukatuka puranga o ngā āhua uaua (pēnei i ngā karāhe āhua korekore) me te whakatutuki i te taratara o te mata iti-nanometer (Ra < 0.6 nm) me te kore e whakauru mai i ngā kino hou o raro i te mata.

ZHHIMG: Tō Hoa Mahi i roto i te Tino Tika

• Ngā Āhuahanga Matatini: Te mīhini i ngā wāhanga whatu āhua-kore, āhua-āporo, me te āhua papatahi.
• Te Ine me te Tirotiro: Te whakamahi i ngā interferometers me ngā profilometers hei manatoko i te kounga o te mata me te tika o te āhua i te wā tonu.
• Tohungatanga Rauemi: He wheako hōhonu ki te silica hanumi, te quartz, me ngā mōhiti whatu motuhake e mōhiotia ana mō te tuku tere me te whakawhānui iti.
