Munyika yekugadzira zvinhu nemazvo, kupisa ndiko muvengi mukuru. Sezvo michina ichifamba, kukweshana kunounza kudziya; sezvo mwenje wefekitori uchirira, tembiricha yemhepo ichichinja; uye sezvo mwaka uchichinja, mhepo chaiyo iri mukati mechinhu inowedzera uye inoderera. Kune zvinhu zvakawanda, kuchinja uku kudiki kunetsa. Asi munyaya yekugadzira nanometer-scale—apo kutsauka kamwe chete kunogona kukanganisa silicon wafer kana kukanganisa optical array yesatellite—kuwedzera kwethermal chinhu chinoparadza. Izvi zvakakonzera kukwira kweZero-Expansion Materials, negranite neceramics yepamusoro zvichibuda semagamba ekutanga enguva yeindasitiri yepamusoro.
Fizikisi yeNheyo "Yakakwana"
Kuti unzwisise kuti sei granite neceramics zvava chinhu chakakosha, munhu anofanira kutanga anzwisisa "Coefficient of Thermal Expansion" (CTE). Kukosha uku kunoyera kuti saizi yechigadzirwa chinochinja zvakadii padanho rekuchinja kwetembiricha. Simbi nearuminiyamu, kunyange zvazvo dzakasimba, dzine CTE dzakakwira. Kana njanji yekuyera yakagadzirwa nesimbi ikakura nema microns mashoma nekuda kwekuchinja kwe1°C, kunyatsojeka kwechikamu chose kunokanganiswa.
Zvinhu zvisingawedzere simba—kana kuti zvinhu zvisingawedzere simba—zvinopa mhinduro nekupa kugadzikana kwakakura. Granite, dombo rechisikigo rinoumbwa nekumanikidzwa kukuru uye kupisa, uye ceramics dzehunyanzvi, dzakagadzirwa kuburikidza nekugadzirwa kwemakemikari kwakanyatsojeka, dzinopa mwero wekuwedzera wakaderera unowanikwa muzvinhu zveindasitiri. Nekushandisa zvinhu izvi se "mubhedha" kana "musana" wemuchina, mainjiniya vanogona kuve nechokwadi chekuti "zero point" yezviyero zvavo inoramba yakasimba zvechokwadi, pasinei nemamiriro ekunze ekupisa.
Granite: Mhinduro yeZvisikwa kuKugadzikana
Granite yagara iri muyero wegoridhe wenheyo dzemetrology. Chakavanzika chayo chiri mukuumbwa kwayo. Yakaumbwa kwemamiriyoni emakore, granite isanganiswa yequartz, mica, uye feldspar. Chimiro ichi chechisikigo "chakasununguka" zvakasikwa. Kusiyana nesimbi, idzo dzinogona kunge dziine kushushikana kwemukati kubva mukuumbwa kana kugadzirwa, granite yagara iine nguva refu yekugara mumamiriro ezvinhu ekuenzana.
Mukugadzira zvinhu zvemhando yepamusoro, zvakaita sekugadzira macircuit eLarge-Scale Integration (LSI), granite inoshanda senzvimbo yemichina ye lithography. Michina iyi inofanira kuratidza mapatani akaomarara pamawafers ane hungwaru hwe sub-micron. Kunyangwe kudedera kudiki kana thermal drift zvingakonzera "blurred" circuit. Kuwanda kweGranite kunopa vibration damping yakanaka, nepo CTE yayo yakaderera ichivimbisa kuti geometry yemukati memuchina inoramba yakaomeswa nechando nekufamba kwenguva.
Uyezve, granite nhema—kunyanya mhando dzakadai se “ZHHIMG Black Granite”—inokosheswa nekuda kwekuwanda kwayo kwemaminerari uye kushoma kwemvura inonyungudika. Izvi zvinoita kuti isanyanya kuzvimba nekuda kwehunyoro, zvichiwedzera imwe nhanho yekugadzikana kune vimbiso ye “Zero-Expansion”. Kana mainjiniya akatsanangura hwaro hwegranite, haasi kungotenga dombo chete; ari kutenga chinhu chinogoneka, chisingachinji.
Zvesimbi Zvepamusoro: Kugadzira Zvisingagoneki
Kunyange zvazvo granite iri basa guru rezvisikwa, zviumbwa zvesimbi zvemhando yepamusoro ndizvo zvinobudirira mukugadzirwa kwevanhu. Zvinhu zvakaita seAlumina (Aluminum Oxide) kana Silicon Carbide zvakagadzirwa kuti zvikwanise kusundira miganhu yezvinhu zvinogoneka mumuviri. Zviumbwa zvesimbi zvinowanzosarudzwa kana granite yasvika pamiganhu yayo—kunyanya maererano nehuwandu hwekurema nekuoma uye mamiriro ekunze anopisa zvakanyanya.
Zvigadzirwa zvesimbi zvemhando yepamusoro zvinogona kugadzirwa kuti zvive neCTE inenge iri zero kana ichienzaniswa netembiricha yakatarwa. Izvi zvinoita kuti zvive zvakakosha kune zvinhu zvinofamba nekumhanya kwakanyanya, senge zvikamu zvinotakura mhepo zvinoshandiswa mukuongorora kwe semiconductor. Nekuti zviumbwa zvesimbi zvakareruka kupfuura granite asi zvakaoma zvakanyanya, zvinobvumira kukurumidza uye kudzikira kwemagetsi pasina "kunonoka" kana kushanduka kunokonzerwa nekusagadzikana.
Muchikamu chezvemuchadenga, maturusi ekuyera zveceramic anoshandiswa kusimbisa zvikamu zvemainjini eroketi nemagirazi eteresikopu. Maturusi aya anofanira kushanda munzvimbo dzine kuchinja kwakanyanya kwekushisa. Hunhu hwe "Zero-Expansion" hweceramics hunovimbisa kuti kuyerwa kunotorwa pa -50°C kwakafanana nekwekutorwa pa +50°C. Iyi nhanho yekuvimbika ndiyo chikonzero nei ceramics dzichiwanzonzi "yepamusoro" metrology material.
Kubatana muChivanze Chemazuva Ano
Mumafekitori emazuva ano akanyanya kufambira mberi, hauwanzowana chinhu chimwe chete. Pane kudaro, unoona kubatana kwakarongeka. Granite inoumba hwaro hukuru, husingafambi—“ivhu” remuchina—ichipa huremu uye hunyoro hunodiwa kuti sisitimu igare pasi. Pamusoro pehwaro uhwu, zvinhu zveceramic zvinobata kufamba nekukurumidza uye zviyero zvakakosha, zvichipa "pfungwa" dzesisitimu.
Musanganiswa uyu uri kutungamira chizvarwa chinotevera chekugadzira zvinhu zvetekinoroji yepamusoro. Sezvatiri kufambira mberi ku2nm chip architecture uye zvichienda mberi, kushivirira kukanganisa kuri zero. Chinhu chega chega chiri muketani yekugadzira chinofanira kubatsira kune "nzvimbo isina kupisa". Nekushandisa Zero-Expansion Materials, vagadziri vanogona kubvisa chimwe chezvinhu zvakaoma zvikuru mu equation yekunyatsojeka.
Kuchinja Kwenyika Yose Kuenda Kukugadzikana
Kudiwa kwezvinhu izvi hakuchashandiswi munzvimbo dzemaindasitiri dzechinyakare. Sezvo kugadzira zvinhu zvetekinoroji yepamusoro kuri kupararira pasi rose, mafambiro ekutumira zvinhu kunze kwenyika idzi "Zero-Expansion" ave indasitiri yehunyanzvi. Kutumira hwaro hwegranite hune matani mashanu kana simbi yeceramic inoputsika inoda zvinopfuura crate chete; zvinoda kunzwisisa kuti zvinhu izvi zvinofamba sei.
Vatengesi vekunze vanotungamira vava kupa zvitupa zvakakwana zvemapu ekupisa uye calibration zvinoratidza kugadzikana kwechigadzirwa mumamiriro akasiyana-siyana. Kujeka uku kunobvumira mugadziri mune imwe nzvimbo yepasi rose kuvaka muchina nechivimbo chekuti hwaro hwayo, hwakabva pakati penyika, hucharamba hwakagadzikana kana yaiswa pasi peimba yekugezera.
Mhedziso: Kuvakira paNheyo Isingachinji
Mashoko ekuti "Zero-Expansion" anopfuura kungotaura nezvehunyanzvi chete; ipfungwa dzekugadzira. Anomiririra kuramba kugamuchira kushanduka-shanduka kwenyika yechisikigo uye kuzvipira kune kururama kwakakwana uye kunodzokororwa. Ingave iri simba rekare regranite, rakagara kwenguva refu kana kunyatsojeka kwezviumbwa zvesimbi zverabhoritari, zvinhu izvi ndizvo zvinobatanidzwa mukubudirira kwese kwetekinoroji kwezana remakore rechi21.
Sezvatinotarisa kune ramangwana—kumakombiyuta equantum, kuongorora nzvimbo yakadzika, uye kupfuura—basa regranite neceramics richangokura chete. Munyika iri kuchinja nguva dzose, zvinhu izvi zvinopa chinhu chimwe chete chinodiwa nekugadzirwa kwehunyanzvi hwepamusoro: nzvimbo yekumira isingambofambi.
