Kei te piki haere te rongonui o ngā rauemi uku hei wāhanga matua o te hangahanga o te ao. Nā te pakeketanga, te ātete ki te pāmahana teitei, me te ātete ki te waikura, he whānuitia te whakamahinga o ngā uku matatau pēnei i te alumina, te silicon carbide, me te konumohe nitride i roto i te rererangi, te takai semiconductor, me ngā tono hauora. Heoi, nā te pakarukaru me te iti o te pakari o ēnei rauemi, kua kiia tonutia he wero uaua te miihini tika. I ngā tau tata nei, me te whakamahinga o ngā taputapu tapahi hou, ngā tukanga hiato, me ngā hangarau aroturuki atamai, kei te āta whakakorea ngā arai miihini uku.
Uauatanga: Te Pakeke Nui me te Pakaru e Noho Tahi Ana
He rerekē ngā konganuku, he ngāwari ake te pakaru me te pakaru o ngā uku i te wā e mahi ana i te mīhini. Hei tauira, he tino mārō te silicon carbide, ā, he tere te memeha o ngā taputapu tapahi tuku iho, ā, ko te roanga o te ora he kotahi-tekau noa iho i te roanga o te mahi mīhini. He mōrearea nui anō hoki ngā pānga wera. Ka taea e te pikinga o te pāmahana ā-rohe i te wā e mahi ana i te mīhini te arahi ki ngā huringa āhua me ngā ahotea toenga, ka hua ake he kino o raro i te mata ka taea te whakararu i te pono o te hua whakamutunga. Mō ngā papa semiconductor, ahakoa te kino o te tauine nanometer ka taea te whakaiti i te wera o te maramara me te mahi hiko.
Te Aranga Hangarau: Ngā Utauta Tapahi Tino Mārō me ngā Tukanga Whakakotahi
Hei whakakore i ēnei wero mīhini, kei te whakauru tonu te umanga i ngā taputapu tapahi hou me ngā otinga arotau tukanga. Kua whakakapia haeretia ngā taputapu tapahi carbide tuku iho e te taimana polycrystalline (PCD) me te taputapu tapahi cubic boron nitride (CBN), ā, kua tino whakapai ake i te ātete ki te kakahu me te pumau o te mīhini. Hei tāpiri, mā te whakamahi i ngā hangarau tapahi āwhina-wiri ultrasonic me te hangarau mīhini rohe-pūngoi kua taea ai te tapahi "pēnei i te kirihou" o ngā rauemi uku, i tangohia i mua mā te pakarukaru anake, ā, nā reira ka whakaitihia te pakaru me te kino o te taha.
Mō te maimoatanga mata, ko ngā hangarau hou pēnei i te whakakanapa matū (CMP), te whakakanapa magnetorheological (MRF), me te whakakanapa āwhina-plasma (PAP) kei te ārahi i ngā wāhanga uku ki te ao o te tika taumata-nanometer. Hei tauira, ko ngā papa totohu wera konumohe nitride, mā te CMP me ngā tukanga PAP, kua eke ki ngā taumata taratara mata i raro i te 2nm, he mea tino nui ki te umanga semiconductor.
Ngā Huarahi Taupānga: Mai i ngā Maramara ki te Hauora
Kei te tere te whakamaoritanga o ēnei whanaketanga hangarau ki ngā tono ahumahi. Kei te whakamahi ngā kaihanga hiko hiko i ngā taputapu mīhini pakari-teitei me ngā pūnaha whakatikatika hapa wera hei whakarite i te pumau o ngā anga uku nui. I roto i te mara koiora, ka miihinihia ngā mata piko uaua o ngā whakaurunga zirconia me te tino tika mā te whakakanapa magnetorheological. I te whakakotahitanga me ngā tukanga laser me te paninga, ka whakarei ake i te hototahitanga koiora me te roa.
Ngā Auahatanga o te Ao: Te Hanganga Maamaa me te Kakariki
I te tirohanga whakamua, ka nui ake te mohio me te atawhai i te taiao o te miihini tika uku. I tetahi taha, kei te whakauruhia te matauranga horihori me ngā māhanga mamati ki roto i ngā tukanga whakaputa, ka taea ai te arotau i ngā ara taputapu, ngā tikanga whakamatao, me ngā tawhā miihini i te wā tūturu. I tetahi atu taha, kei te noho te hoahoa uku whakarara me te hangarua para hei wāhi rangahau, e whakarato ana i ngā huarahi hou mō te hanga matomato.
Whakamutunga
E kitea ana ka whanake tonu te miihini tika uku ki te "tino-tika, iti te kino, me te whakahaere atamai." Mō te umanga hanga o te ao, ehara i te mea he putanga hou tēnei i roto i te tukatuka rauemi engari he tohu nui hoki mō te whakataetae ā-muri i roto i ngā umanga teitei. Hei wāhanga matua o te hanga matatau, ka akiaki tika ngā whanaketanga auaha i roto i te miihini uku i ngā umanga pēnei i te rererangi, ngā semiconductors, me te koiora ki ngā taumata hou.
