Kwihlabathi lemveliso echanekileyo kakhulu, ubushushu lolona tshaba luphambili. Njengoko oomatshini besebenza, ukungqubana kuvelisa ubushushu; njengoko izibane zefektri ziduma, amaqondo obushushu atshintsha; kwaye njengoko amaxesha onyaka etshintsha, umoya ngaphakathi kwesakhiwo uyakhula kwaye uncipha. Kwiinto ezininzi, olu tshintsho luyingxaki encinci. Kodwa kwicandelo lokwenziwa kwesikali se-nanometer—apho ukuphambuka okukodwa kunokonakalisa i-silicon wafer okanye kungayilungelelanisi kakuhle i-optical array yesathelayithi—ukwanda kobushushu lutshintsho olukhulu. Oku kukhokelele ekunyukeni kweZero-Expansion Materials, apho i-granite kunye ne-ceramics eziphambili zivela njengamaqhawe asisiseko kwixesha leemveliso zobugcisa obuphezulu.
Ifiziksi yeSiseko "esigqibeleleyo"
Ukuze uqonde ukuba kutheni i-granite kunye neeseramikhi ziye zaba yinto efunekayo, umntu kufuneka aqale aqonde "i-Coefficient of Thermal Expansion" (CTE). Eli xabiso lilinganisa ukuba ubungakanani bezinto butshintsha kangakanani ngokweqondo lokutshintsha kobushushu. Intsimbi kunye ne-aluminium, nangona ziqinile, zine-CTE eziphezulu. Ukuba umzila wokulinganisa owenziwe ngentsimbi ukhula ngee-microns ezimbalwa ngenxa yokutshintsha kwe-1°C, ukuchaneka kwendibano yonke kuyaphazamiseka.
Izixhobo ezingandi kakhulu—okanye ngokuchanekileyo, izixhobo ezingandi kakhulu—zibonelela ngesisombululo ngokubonelela ngozinzo oluphantse lube nobukhulu obupheleleyo. I-Granite, ilitye lendalo eliyi-igneous elenziwe phantsi koxinzelelo olukhulu nobushushu, kunye neeseramikhi zobugcisa, ezenziwe ngokwenziwa kweekhemikhali ngokuchanekileyo, zibonelela ngamanani aphantsi okwanda afumanekayo kwizixhobo zomgangatho wemizi-mveliso. Ngokusebenzisa ezi zinto "njengebhedi" okanye "umqolo" womatshini, iinjineli zinokuqinisekisa ukuba "inqaku le-zero" lokulinganisa kwazo lihlala lizinzile ngokwenene, nokuba imeko yobushushu injani na.
I-Granite: Impendulo yendalo yozinzo
I-granite ibisoloko iyindlela esemgangathweni yegolide kwiziseko ze-metrology. Imfihlo yayo ikwindlela ekwakhiwe ngayo. I-granite, eyakhiwe kwiminyaka eyi-2000 eyadlulayo, yenziwe nge-quartz, i-mica, kunye ne-feldspar. Olu lwakhiwo lwendalo "lukhululekile" ngokwemvelo. Ngokungafaniyo neentsimbi, ezinokuba noxinzelelo lwangaphakathi oluvela kwinkqubo yokubumba okanye yokubumba, i-granite ibisoloko izinzile kwimeko yokulingana.
Kwimveliso yobuchwepheshe obuphezulu, njengokuveliswa kweesekethe zeLarge-Scale Integration (LSI), igranite isebenza njengesiseko soomatshini be-lithography. Aba matshini kufuneka baveze iipatheni ezintsonkothileyo kwii-wafers ezichanekileyo kwi-sub-micron. Nokuba kungcangcazela okanye ukushukuma okuncinci kwe-thermal kuya kubangela isekethe "efipheleyo". Uxinano oluphezulu lweGranite lubonelela ngokudambisa okugqwesileyo kokungcangcazela, ngelixa i-CTE yayo ephantsi iqinisekisa ukuba i-geometry yangaphakathi yomatshini ihlala iqandisiwe ngexesha.
Ngaphezu koko, i-granite emnyama—ngakumbi iintlobo ezifana ne-“ZHHIMG Black Granite”—ixatyiswa kakhulu ngenxa yobuninzi bayo beeminerali kunye nokufunxwa kwamanzi kancinci. Oku kuyenza imelane nokudumba okubangelwa kukufuma, kongeza olunye ungqimba lozinzo kwisithembiso esithi “Zero-Expansion”. Xa injineli icacisa isiseko se-granite, ayithengi nje ilitye; ithenga i-consistent ebonakalayo eqikelelweyo, engatshintshiyo.
Iiceramics Eziphambili: Ubunjineli Obungenakwenzeka
Nangona i-granite iyinto yobugcisa yendalo, ii-ceramics eziphambili ziyimpumelelo yobunjineli babantu. Izinto ezifana ne-Alumina (i-Aluminum Oxide) okanye i-Silicon Carbide zenziwe ngendlela yokuba zityhale imida yoko kunokwenzeka ngokwasemzimbeni. Ii-ceramics zihlala zizinto ezikhethwayo xa i-granite ifikelela kwimida yayo—ingakumbi ngokubhekiselele kumlinganiselo wobunzima nokuqina kunye neendawo ezishushu kakhulu.
Iiceramics eziphambili zinokwakhiwa ukuze zibe ne-CTE ephantse ibe zero kuluhlu oluthile lobushushu. Oku kuzenza zibe yimfuneko kwizinto ezihamba ngesantya esiphezulu, njengezigaba zomoya ezisetyenziswa ekuhlolweni kwe-semiconductor. Ngenxa yokuba iiceramics zikhaphukhaphu kunegranite kodwa ziqinile kakhulu, zivumela ukukhawulezisa ngokukhawuleza kunye nokucotha ngaphandle "kokugqwala" okanye ukuguqulwa okubangelwa yi-inertia.
Kwicandelo leenqwelo-moya, izixhobo zokulinganisa iseramikhi zisetyenziselwa ukuqinisekisa izinto zeenjini zerokhethi kunye nezibuko zeteleskopu. Ezi zixhobo kufuneka zisebenze kwiindawo apho ubushushu butshintsha kakhulu khona. Uphawu "lokwanda okungaphelelanga" lweeseramikhi luqinisekisa ukuba umlinganiselo othathwe kwi -50°C uyafana nalowo othathwe kwi +50°C. Eli nqanaba lokuthembeka yingakho iiseramikhi zihlala zibizwa ngokuba zizinto "eziphambili" zemetrology.
Ukusebenzisana kwiGumbi lokuCoca lanamhlanje
Kwimizi-mveliso yanamhlanje ephucukileyo, akunakufane ufumane nto inye kuphela. Endaweni yoko, ubona intsebenziswano yeqhinga. I-granite yenza isiseko esikhulu, esingashukumiyo—“umhlaba” womatshini—esinika ubunzima kunye nokufuma okufunekayo ukuze inkqubo ihlale phantsi. Phezu kwesi siseko, izinto zeseramikhi zisingatha intshukumo yesantya esiphezulu kunye nokulinganisa okubalulekileyo, okubonelela “ngengqondo” yenkqubo.
Olu dibaniso luqhuba isizukulwana esilandelayo sokwenziwa kwemveliso yobuchwepheshe obuphezulu. Njengoko sisiya kwisakhiwo se-2nm chip nangaphezulu, ukunyamezela iimpazamo ngokuqinisekileyo kungu-zero. Yonke into kwikhonkco lokwenziwa kwemveliso kufuneka ifake isandla kwindawo "engathathi hlangothi kwe-thermal". Ngokusebenzisa izixhobo ze-Zero-Expansion, abavelisi banokususa enye yezona zinto zinzima kwi-equation yokuchaneka.
Utshintsho Lwehlabathi Lonke Oluya Kuzinzo
Imfuno yezi zinto ayisasetyenziswa kwiindawo zoshishino zemveli. Njengoko imveliso yobuchwepheshe obuphezulu isasazeka kwihlabathi liphela, ukuthunyelwa kwezi ziseko ze-"Zero-Expansion" kuye kwaba lishishini elikhethekileyo. Ukuthunyelwa kwesiseko segranite esineetoni ezintlanu okanye umzila werayile obuthathaka weceramic kufuna okungaphezulu nje kwekreyithi; kufuna ukuqonda indlela eziziphatha ngayo ezi zinto.
Abathengisi abaphambili ngoku banikezela ngeesatifikethi ezipheleleyo zemephu yobushushu kunye nokulinganisa ezibonisa uzinzo lwezixhobo phantsi kweemeko ezahlukeneyo. Oku kucaca kuvumela umenzi kwelinye icala lehlabathi ukuba akhe umatshini ngokuqiniseka okupheleleyo ukuba isiseko sawo, esivela embindini wehlabathi, siya kuhlala sizinzile xa sibotshelelwe kumgangatho wegumbi lokucoca.
Isiphelo: Ukwakha kwiSiseko Esingaguqukiyo
Ibinzana elithi “Zero-Expansion” lingaphezulu nje kwenkcazelo yobugcisa; yifilosofi yokuvelisa. Limela ukwala ukwamkela ukuguquguquka kwendalo kunye nokuzibophelela ekuchanekeni okugqibeleleyo nokuphindaphindiweyo. Nokuba ngamandla amandulo egranite, aguqukileyo okanye ukuchaneka kwe-ceramics okucwangcisiweyo kwilebhu, ezi zinto zingamaqabane athuleyo kuyo yonke inkqubela phambili yetekhnoloji yenkulungwane yama-21.
Njengoko sijonge kwixesha elizayo—kwi-quantum computing, uphando lwesithuba esinzulu, nangaphaya—indima yegranite kunye neeseramikhi iya kukhula kuphela. Kwihlabathi elihlala litshintsha, ezi zinto zibonelela ngento enye efunwa kakhulu kukwenziwa kwemveliso yobuchwepheshe obuphezulu: indawo yokuma engashukumiyo.
