Muhondo yekupedzisira ye "nanoprecision" mukugadzira semiconductor, kunyangwe kakanganiso kadiki mumidziyo yekucheka wafer inogona kushandura chip kuita dongo. Iyo granite base ndiyo gamba risingaverengeki rinotonga iyo ± 5um kudzokorora chinzvimbo, kunyora patsva mitemo yekugadzira nemazvo nematatu ayo echisikigo zvinoshamisa.
Iyo "kudzikamisa anchor" inopesana nemafuta deformation: Iyo coefficient yekupisa kwekuwedzera kwegranite yakadzikira se5-7 × 10⁻⁶/℃, inongori chikamu chimwe chete muzvitatu chezvigadzirwa zvesimbi. Pasi pesimba rekupisa rinogadzirwa neakakwira-kumhanya kushanda kwewafer yekucheka midziyo, zvakajairwa zvinokanganisa nekuda kwekuwedzera kwekupisa uye kudonha, zvichikonzera kumira kwemusoro wekucheka kuchinja. Nekudaro, iyo base yegranite inogona kuramba "isina kufamba", zvakanyanya kubvisa iyo yekumisikidza kutsauka kunokonzerwa nekupisa kwemafuta uye nekuisa hwaro hwakasimba hwekunyatso.
Iyo "chinyararire nhovo" ye vibration absorption: Iyo inogara ichitinhira yezvishandiso zvemuchina uye kuenderera mberi kwekudedera kwemidziyo muwekishopu kunogona kutorwa se "mhondi dzinouraya" nemazvo. Iyo yakasarudzika yekristaro chimiro chegranite yakafanana neyechisikigo inonwisa, inokwanisa kukurumidza kushandura kudengenyeka kwekunze uye ma mechanical vibrations anogadzirwa nekushandisa kwemidziyo kuita kupisa kwesimba rekuparara. Nepo mamwe mabhesi achiri "kuzununguka" nekuda kwekudengenyeka, iyo granite base yakagadzira yakagadzikana chikuva chemusoro wekucheka unoramba uchifamba, zvichiita ± 5um kunyatsoita.
Corrosion-resistant "Eternal Fortress" : Semiconductor mashopu akazadzwa nezvinhu zvinoparadza senge etching mhinduro uye acid uye alkali cleaners. Munharaunda yakadai, mabhesi esimbi achaita ngura zvishoma nezvishoma uye anokanganisa. Granite, nekugadzikana kwayo kwemakemikari, haiite nemakemikari zvinhu zvachose. Hazvina mhosva kuti imakore mangani iyo inoshandiswa, inogona kuchengetedza kutendeseka kwechimiro uye inoramba ichivimbisa yakakwirira-chaiyo yekucheka.
Kubva pane tarenda rezvinhu kusvika ku-ultra-precision processing, iyo granite base yakaratidza nesimba rayo kuti hazvisi zvese zvigadzirwa zvinogona kusangana nematambudziko akaomarara ekugadzira semiconductor. Izvo chaizvo nekuda kweaya mabhenefiti echisikigo asingadzokerike ayo mabhesi egranite ave kiyi yekucheka wafer midziyo kuti iwane kudzokorora chinzvimbo che ± 5um, uye yakawedzera kufambisa iyo semiconductor indasitiri kuti irambe ichienda kune yakakwira chaiyo!
