Mu isi y’inganda zikora ibintu neza cyane, ubushyuhe ni wo mwanzi ukomeye. Uko imashini zikora, gukururana bitera ubushyuhe; uko amatara yo mu ruganda avuza ubushyuhe, ubushyuhe bwo mu kirere buhinduka; kandi uko ibihe bihinduka, umwuka uri mu kigo uragenda wiyongera kandi ugatandukana. Ku bintu byinshi, uku guhindagurika ni ikibazo gito. Ariko mu rwego rwo gukora nanometer-scale - aho guhindagurika rimwe bishobora kwangiza silicon wafer cyangwa kugorana imiterere y’urumuri rwa satelite - kwaguka k’ubushyuhe ni ikintu giteye ubwoba. Ibi byatumye habaho kwiyongera kwa Zero-Expansion Materials, aho granite na ceramics zigezweho zigaragara nk'intwari z'ibanze zo mu gihe cy'inganda zigezweho.
Fiziki y'Ikigo "Kitunganye"
Kugira ngo umuntu asobanukirwe impamvu granite na ceramics byabaye ngombwa, agomba kubanza gusobanukirwa "Coefficient of Thermal Expansion" (CTE). Aka gaciro gapima ingano y'ibikoresho bihinduka ku gipimo cy'impinduka z'ubushyuhe. Ibyuma na aluminiyumu, nubwo bikomeye, bifite CTE nyinshi. Iyo umuyoboro wo gupima ukozwe mu cyuma ukura na mikoroni nke bitewe n'impinduka ya 1°C, ubwiza bw'iteraniro ryose buragabanuka.
Ibikoresho bidakura cyane—cyangwa ibikoresho bidakura cyane—bitanga igisubizo binyuze mu gutanga ubudahinduka mu rugero rungana na ruto. Granite, ibuye karemano rikozwe mu buryo bw'umuvuduko n'ubushyuhe bwinshi, hamwe n'ibinyabutabire bya tekiniki, byakozwe binyuze mu guhuza neza ibinyabutabire, bitanga igipimo cyo kwaguka kiri hasi cyane kiboneka mu bikoresho byo mu nganda. Mu gukoresha ibi bintu nk' "uburiri" cyangwa "umugongo" w'imashini, abahanga bashobora kwemeza ko "ingingo ya zeru" y'ibipimo byabo iguma ihamye koko, hatitawe ku bidukikije by'ubushyuhe.
Granite: Igisubizo cy'ibidukikije ku gutuza
Granite imaze igihe kinini ari yo ikoreshwa cyane mu gupima. Ibanga ryayo riri mu miterere yayo. Yakozwe mu myaka ya za miriyoni, granite ni igizwe na quartz, mica, na feldspar. Iyi miterere karemano isanzwe "iraruhutse." Bitandukanye n'ibyuma, bishobora kugira imbaraga zo imbere mu gucukura cyangwa gucura, granite yamaze igihe kirekire ihinduka mu buryo bw'uburinganire.
Mu nganda zigezweho, nko gukora imiyoboro ya Large-Scale Integration (LSI), granite ikoreshwa nk'ishingiro ry'imashini zitunganya imiyoboro. Izi mashini zigomba gushyira imiterere igoye ku miyoboro ya wafer ifite ubushobozi bwo gukora neza. Nubwo byagera ku guhindagurika guke cyangwa gushyuha cyane byatuma habaho imiyoboro "ihindagurika". Ubucucike bwinshi bwa Granite butanga uburyo bwiza bwo kudakoresha imiyoboro, mu gihe CTE yayo nke ituma imiterere y'imbere y'imashini ikomeza kuba ikonje mu gihe runaka.
Byongeye kandi, granite y'umukara—cyane cyane ubwoko nka “ZHHIMG Black Granite”—ihabwa agaciro kubera ubucucike bwayo bwinshi bw'amabuye y'agaciro n'amazi make adashobora kwinjiza. Ibi bituma idapfa kubyimba bitewe n'ubushuhe, bikongeraho urundi rwego rwo kudahinduka ku isezerano rya “Zero-Expansion”. Iyo injeniyeri agennye ishingiro rya granite, ntabwo aba agura ibuye gusa; aba agura ishingiro ry'umubiri ritegerejwe kandi ridahinduka.
Ubuhanga mu by'Ibumba Bugezweho: Guhanga mu by'Ubuhanga mu Bidashoboka
Nubwo granite ari igishushanyo mbonera cy’ibidukikije, ibumba rigezweho ni intsinzi y’ubuhanga bw’abantu. Ibikoresho nka Alumina (Aluminum Oxide) cyangwa Silicon Carbide byakozwe kugira ngo bisunike imbibi z’ibishoboka ku mubiri. Ibumba rikunze kuba ibikoresho bikundwa iyo granite igeze ku mbibi zayo—cyane cyane mu bijyanye n’uburemere n’ubukonje ndetse n’ikirere gishyushye cyane.
Ibumba rigezweho rishobora gukorwa kugira ngo rigire CTE hafi ya zeru ugereranyije n'ubushyuhe runaka. Ibi bituma ari ingenzi ku bice bigenda ku muvuduko wo hejuru, nko mu byiciro byo gutwara umwuka bikoreshwa mu igenzura rya semiconductor. Kubera ko ibumba ritoroshye kurusha granite ariko rigakomera cyane, rituma rirushaho kwihuta no kugabanuka kw'umuvuduko w'amashanyarazi nta "gutinda" cyangwa guhinduka bitewe n'ubushyuhe.
Mu rwego rw'indege, ibikoresho byo gupima ceramic bikoreshwa mu kugenzura ibice bya moteri za roketi n'indorerwamo za telesikope. Ibi bikoresho bigomba gukora ahantu ubushyuhe bukabije buhindagurika. Ikiranga "Zero-Expansion" cya ceramics gihamya ko igipimo gifatwa kuri -50°C gisa n'igifatwa kuri +50°C. Uru rwego rwo kwizerwa niyo mpamvu ceramics zikunze kwitwa "ibikoresho by'ingenzi" byo gupima ikirere.
Ubufatanye mu cyumba cyo gusukura cya none
Mu nganda zigezweho cyane muri iki gihe, ntabwo uzabona ibikoresho bimwe gusa. Ahubwo, ubona ubufatanye buhamye. Granite ikora ishingiro rinini, ritanyeganyega—“ubutaka” bw’imashini—itanga uburemere n’ubushuhe bikenewe kugira ngo sisitemu ishinge hasi. Hejuru y’iri shingiro, ibice bya ceramic bikora ingendo zihuse cyane n’ibipimo by’ingenzi, bigatanga “ubwenge” bw’iyi sisitemu.
Uku guhuza kurimo kuyobora igisekuru gitaha cy’inganda zikoresha ikoranabuhanga rigezweho. Uko tugenda tugera ku miterere ya chip ya 2nm no kurenzaho, kwihanganira amakosa ni zeru rwose. Buri gice cyose kiri mu ruhererekane rw’inganda kigomba kugira uruhare mu "bushyuhe butagira aho bubogamiye". Bakoresheje ibikoresho bya Zero-Expansion, abakora bashobora gukuraho kimwe mu bintu bigoye cyane mu gupima neza.
Impinduka ku Isi Igana ku Gutuza
Ubusabe bw'ibi bikoresho ntibukigaragara mu nganda gakondo. Uko inganda zikora ikoranabuhanga rihanitse zikwirakwira hirya no hino ku isi, imikorere yo kohereza mu mahanga ibi bikoresho byitwa "Zero-Expansion" yabaye inganda zihariye. Kohereza ibikoresho by'ibanze bya granite bya toni eshanu cyangwa icyuma cyoroshye cya ceramic bisaba ibirenze isanduku gusa; bisaba gusobanukirwa uko ibyo bikoresho byitwara.
Abashoramari bakomeye bo mu mahanga ubu batanga ibyemezo byuzuye byo gupima ubushyuhe n'ubuziranenge bigaragaza ko ibikoresho bihamye mu bihe bitandukanye. Uku gukorera mu mucyo kwemerera uruganda mu gice kimwe cy'isi kubaka imashini yizeye neza ko urufatiro rwayo, rukomoka hagati y'isi, ruzakomeza gukomera igihe cyose izaba ishyizwe ku igorofa ry'icyumba cy'isuku.
Umwanzuro: Kubaka ku rufatiro rudahinduka
Interuro "Zero-Growth" irenze ibisobanuro bya tekiniki gusa; ni filozofiya y'inganda. Igaragaza kwanga kwemera ihindagurika ry'isi karemano no kwiyemeza gukora neza kandi gusubirwamo. Byaba ari imbaraga za kera za granite, zaranzwe n'ihindagurika cyangwa ubuziranenge bw'ibibumbano bwa kera, bwakozwe muri laboratwari, ibi bikoresho ni abafatanyabikorwa batagira icyo bavuga muri buri terambere ry'ikoranabuhanga ryo mu kinyejana cya 21.
Mu gihe tureba ahazaza—kubara quantum, gushakisha mu kirere cyimbitse, n'ibindi byinshi—uruhare rwa granite na ceramics ruzakura gusa. Mu isi ihora ihinduka, ibi bikoresho bitanga ikintu kimwe inganda zigezweho zikeneye cyane: ahantu ho guhagarara hatazigera hahinduka.
