Ezweni lokukhiqiza okunembe kakhulu, ukushisa kuyisitha esikhulu. Njengoba imishini isebenza, ukungqubuzana kudala ukufudumala; njengoba izibani zasefektri zivungazela, amazinga okushisa ashintshashintshayo; futhi njengoba izinkathi zonyaka zishintsha, wona kanye umoya ngaphakathi kwesakhiwo uyakhula futhi unciphe. Ezintweni eziningi, lokhu kuguquguquka kuyinkathazo encane. Kodwa emkhakheni wokwenziwa kwesikali se-nanometer—lapho ukuphambuka okukodwa kungonakalisa i-silicon wafer noma kungayiqondisi kahle i-optical array yesethelayithi—ukwanda kokushisa kuyinguquko embi kakhulu. Lokhu kuholele ekukhuleni kwezinto ze-Zero-Expansion, lapho i-granite kanye ne-ceramics ezithuthukisiwe zivela njengamaqhawe ayisisekelo enkathini yezimboni yobuchwepheshe obuphezulu.
I-physics yeSisekelo "Esiphelele"
Ukuze uqonde ukuthi kungani i-granite kanye ne-ceramics sezibe yinto ebaluleke kakhulu, umuntu kumele aqale aqonde "i-Coefficient of Thermal Expansion" (CTE). Leli nani lilinganisa ukuthi ubukhulu bezinto bushintsha kangakanani ngokwezinga lokushintsha kwezinga lokushisa. Insimbi ne-aluminium, nakuba ziqinile, zine-CTE ephezulu. Uma isitimela sokulinganisa esenziwe ngensimbi sikhula ngisho nangama-micron ambalwa ngenxa yokushintsha kwe-1°C, ukunemba kwenhlangano yonke kuyaphazamiseka.
Izinto ezingakhuli kakhulu—noma ngokunembe kakhulu, izinto ezingakhuli kakhulu—zinikeza ikhambi ngokunikeza ukuzinza okucishe kube nobukhulu obuphelele. I-Granite, idwala lemvelo eliyi-igneous elakhiwe ngaphansi kwengcindezi enkulu nokushisa, kanye ne-ceramics yobuchwepheshe, eyenziwe ngokuhlanganiswa kwamakhemikhali okunembile, inikeza amazinga okwanda aphansi kakhulu atholakala ezintweni zezimboni. Ngokusebenzisa lezi zinto “njengombhede” noma “umgogodla” womshini, onjiniyela bangaqinisekisa ukuthi “iphuzu lika-zero” lokulinganisa kwabo lihlala lizinzile ngempela, kungakhathaliseki ukuthi indawo eshisayo injani.
I-Granite: Impendulo Yemvelo Ekuzinzeni
I-granite ibilokhu iyindinganiso yegolide yezisekelo ze-metrology. Imfihlo yayo isekwakhekeni kwayo. Njengoba yakhiwe eminyakeni eyizigidi, i-granite iyinhlanganisela ye-quartz, i-mica, ne-feldspar. Lesi sakhiwo semvelo "sikhululekile" ngokwemvelo. Ngokungafani nezinsimbi, ezingase zibe nokucindezeleka kwangaphakathi okuvela enkambisweni yokubumba noma yokuthunga, i-granite ibilokhu inamandla okuphila esimweni sokulingana.
Ekwenzeni izinto zobuchwepheshe obuphezulu, njengokukhiqizwa kwezifunda ze-Large-Scale Integration (LSI), i-granite isebenza njengesisekelo semishini ye-lithography. Le mishini kumele iveze amaphethini ayinkimbinkimbi kuma-wafers anokunemba kwe-sub-micron. Ngisho nokudlidliza okuncane noma ukukhukhuleka kokushisa kungaholela kumjikelezo "ofiphele". Ubuningi obukhulu be-Granite buhlinzeka ngokudambisa ukudlidliza okuhle kakhulu, kuyilapho i-CTE yayo ephansi iqinisekisa ukuthi i-geometry yangaphakathi yomshini ihlala iqandisiwe ngesikhathi.
Ngaphezu kwalokho, i-granite emnyama—ikakhulukazi izinhlobo ezifana ne-“ZHHIMG Black Granite”—iyaziswa ngenxa yobuningi bayo obukhulu bamaminerali kanye nokumuncwa kwamanzi okuncane. Lokhu kuyenza imelane nokuvuvukala okubangelwa umswakama, okwengeza olunye ungqimba lokuqina esithembisweni esithi “Zero-Expansion”. Uma unjiniyela ecacisa isisekelo se-granite, akagcini nje ngokuthenga idwala; kodwa uthenga i-consistent ebonakalayo engashintshi, engabikezelwa.
I-Ceramics Ethuthukisiwe: Ubunjiniyela Obungenakwenzeka
Nakuba i-granite iwumsebenzi wobuciko wemvelo, i-ceramics ethuthukisiwe iwukunqoba kobunjiniyela babantu. Izinto ezifana ne-Alumina (i-Aluminum Oxide) noma i-Silicon Carbide zenzelwe ukusunduza imingcele yalokho okungenzeka ngokomzimba. I-ceramics ivame ukuba yizinto ezikhethwayo lapho i-granite ifinyelela imingcele yayo—ikakhulukazi ngokwesilinganiso sokuqina kwesisindo kanye nezimo ezishisayo kakhulu.
Izitsha zobumba ezithuthukisiwe zingaklanywa ukuze zibe ne-CTE ecishe ibe yi-zero ngaphezu kobubanzi obuthile bokushisa. Lokhu kuzenza zibaluleke kakhulu ezingxenyeni ezihamba ngesivinini esiphezulu, njengezigaba zokuthwala umoya ezisetshenziswa ekuhlolweni kwe-semiconductor. Ngenxa yokuthi izitsha zobumba zilula kune-granite kodwa ziqinile kakhulu, zivumela ukusheshisa okusheshayo kanye nokwehla kwejubane ngaphandle "kokugqwala" noma ukuguqulwa okubangelwa yi-inertia.
Emkhakheni wezindiza, amathuluzi okulinganisa i-ceramic asetshenziswa ukuqinisekisa izingxenye zezinjini ze-rocket kanye nezibuko ze-telescope. Lawa mathuluzi kumele asebenze ezindaweni lapho izinga lokushisa lishintsha kakhulu khona. Isici "se-Zero-Expansion" se-ceramics siqinisekisa ukuthi isilinganiso esithathwe ku--50°C sifana nalesi esithathwe ku-+50°C. Leli zinga lokuthembeka yingakho i-ceramics ivame ukubizwa ngokuthi izinto "eziphezulu" ze-metrology.
Ukusebenzisana Egumbini Lokuhlanza Lanamuhla
Emafektri athuthuke kakhulu namuhla, ngeke uthole lutho olulodwa kuphela. Esikhundleni salokho, ubona ukusebenzisana okunesu. I-Granite yakha isisekelo esikhulu, esingashukumi—“umhlaba” womshini—esinikeza isisindo kanye nokumanzisa okudingekayo ukuze kufakwe uhlelo phansi. Phezu kwalesi sisekelo, izingxenye ze-ceramic zisingatha ukunyakaza okusheshayo kanye nokulinganisa okubucayi, okunikeza “ukuhlakanipha” kohlelo.
Le nhlanganisela iqhuba isizukulwane esilandelayo sokukhiqiza ngobuchwepheshe obuphezulu. Njengoba siqhubekela phambili ekwakhiweni kwama-chip angu-2nm nangale kwalokho, ukubekezelela amaphutha empeleni kungu-zero. Yonke ingxenye eketangeni lokukhiqiza kumele ifake isandla endaweni "engathathi hlangothi kwe-thermal". Ngokusebenzisa Izinto Zokukhulisa Ezingashintshi, abakhiqizi bangasusa enye yezinguquko ezinzima kakhulu ku-equation yokunemba.
Ushintsho Lomhlaba Wonke Oluya Ekuzinzeni
Isidingo salezi zinto asisatholakali ezindaweni zezimboni zendabuko. Njengoba ukukhiqizwa kobuchwepheshe obuphezulu kusakazeka emhlabeni wonke, ukuthunyelwa kwalezi zisekelo ze-“Zero-Expansion” sekuphenduke imboni ekhethekile. Ukuthunyelwa kwesisekelo se-granite esingamathani amahlanu noma isitimela esikhulu se-ceramic esibuthakathaka kudinga okungaphezu nje kwe-crate; kudinga ukuqonda ukuthi lezi zinto ziziphatha kanjani.
Abathumeli abaphambili manje banikeza izitifiketi eziphelele zokuhlola ukushisa kanye nokulinganisa ezifakazela ukuqina kwezinto ngaphansi kwezimo ezahlukahlukene. Lokhu kucaca kuvumela umenzi engxenyeni ethile yomhlaba ukuthi akhe umshini ngokuqiniseka okuphelele kokuthi isisekelo sawo, esivela phakathi komhlaba wonke, sizohlala sizinzile ngesikhathi uboshelwa phansi endlini yokuhlanza.
Isiphetho: Ukwakha Esisekelweni Esingaguquki
Inkulumo ethi “Zero-Expansion” ingaphezu nje kwencazelo yobuchwepheshe; iyifilosofi yokukhiqiza. Imelela ukwenqaba ukwamukela ukuguquguquka komhlaba wemvelo kanye nokuzibophezela ekunembeni okuphelele nokuphindaphindekayo. Kungakhathaliseki ukuthi kunamandla asendulo e-granite aguqukile noma ukunemba kwe-ceramics okulungiselelwe ikusasa, okwenziwe elebhu, lezi zinto zingabalingani abathule kuyo yonke intuthuko yezobuchwepheshe yekhulu lama-21.
Njengoba sibheke esikhathini esizayo—ekubalweni kwe-quantum, ukuhlola isikhala esijulile, nangale kwalokho—indima ye-granite kanye ne-ceramics izokhula kuphela. Ezweni elihlala lishintsha, lezi zinto zinikeza into eyodwa edingwa kakhulu ukukhiqiza ubuchwepheshe obuphezulu: indawo yokuma engalokothi inyakaze.
