Munyika chaiyo yekugadzira semiconductor, kuyedzwa kwemawafers asingaparadze chinhu chakakosha chekuona kuti machipisi akanaka sei. Hwaro hwegranite hunoratidzika kunge husina basa ndiro "gamba risingazivikanwe" rinosarudza kururama kwekuona. Zvinokanganisa sei mhedzisiro yebvunzo? Chinyorwa chino chichaita ongororo yakadzama kubva pahukuru hwakadai sehunhu hwezvinhu uye dhizaini yezvivakwa.
1. Nheyo Yakagadzikana: Mabhenefiti echisikigo egranite anoisa hwaro hwakasimba hwekuita zvinhu nemazvo
1. Kushanda kwakanaka kwazvo kwekudengenyeka kwenyika
Munguva yekushanda kwemidziyo yekuedza isingaparadze yewafer, kutenderera kwemota nekufamba kwezvikamu zvemakanika zvese zvinogadzira kudedera. Kana kudedera uku kukasadziviswa zvakanaka, kuchakanganisa zvakanyanya kururama kwekuyedza. Mukati megranite makabatana zvakanyanya nemakristaro emaminerari akadai sequartz nefeldspar. Chimiro chayo chakasiyana chinoita kuti ive nekugona kwechisikigo kwekukwevera kudedera, inokwanisa kutora anopfuura 90% yesimba rekukwevera remidziyo. Data chaiyo yekuyera yemumwe mugadziri we semiconductor inoratidza kuti mushure mekushandisa granite base, vibration amplitude yemidziyo yekuona yakaderedzwa kubva pa12μm kusvika pa2μm, zvichidzivirira kutsauka kwechiratidzo chekuona kunokonzerwa nekukwedera.
2. Kuwanda kwemafuta kwakaderera zvakanyanya
Munguva yekuona, zvinhu zvakaita sekudziya kwemidziyo uye kuchinja kwekupisa kwezvakatipoteredza zvese zvinokanganisa kugadzikana kwebase remuchina. Zvinhu zvakajairika zvinowedzera zvakanyanya kana zvapiswa, asi coefficient yekuwedzera kwekushisa kwegranite i1/5 chete yesimbi. Kunyangwe tembiricha yemhepo ikachinja-chinja ne10℃, kushanduka kwayo kunogona kuregeredzwa. Izvi zvinogonesa base regranite kupa puratifomu yakagadzikana yekutarisa michina yekuongorora, ichivimbisa kuti nzvimbo iri pakati peprobe yekuongorora newafer inoramba yakarurama nguva dzese uye ichidzivirira zvikanganiso zvekuongorora zvinokonzerwa nekushanduka kwekushisa.
Chechipiri, dhizaini chaiyo: Kugadziriswa kwechivakwa kunowedzera kuvimbika kwekuona
Kugadziriswa kwakanyatsonaka uye vimbiso ye flatness
Hwaro hwegranite hwemhando yepamusoro hunogadziriswa netekinoroji yepamusoro yeCNC yekubatanidza mativi mashanu, ine hurefu hwe±0.5μm/m, zvichipa mukana wekuisa michina yekuongorora. Mukuongorora kwewafer, kumira uye kuenzana kweprobe yekuongorora kwakakosha kumhedzisiro yekuongorora. Hwaro hwegranite hwakanyatsojeka hunogona kuve nechokwadi chekuti probe iri panzvimbo chaiyo, zvichiita kuti data rekuongorora rive rakarurama uye rakavimbika.
2. Kugadziriswa kwechimiro chakagadzirwa
Mabhesi emuchina wegranite anogona kugadziriswa kuti ashandiswe mumidziyo yakasiyana-siyana yekuedza isingaparadze uye zvinodiwa pakuita. Semuenzaniso, kuti zvienderane nezvinodiwa zvemichina yekuongorora yemaziso kuti ionekwe nechiedza, pamusoro pebhesi remuchina unogona kugadziriswa zvakanyanya; Kuti zvienderane nezvinodiwa zvekuisa michina yekuongorora ye ultrasonic, bhesi rinogona kugadzirwa nemaburi chaiwo ekuisa uye matireyi etambo, zvichiita kuti kuiswa kwemuchina nekukurumidza uye kwakarurama kuderedzwa uye kuderedza kutsauka kunokonzerwa nekukanganisa kwekuisa.
III. Kugadzikana kwenguva refu: Kuderedza kurasikirwa kwakarurama kunokonzerwa nekugadzirisa michina
Granite ine kuomarara kwakanyanya uye yakasimba, ine kuomarara kweMohs kwe6 kusvika ku7, inova katatu simba rekudzivirira kupera kupfuura simbi yakajairika. Munguva yekuongorora kwenguva refu, pamusoro pechigadziko chemuchina hachiwanzo pera uye chinogona kugara chakanyatsojeka. Kusiyana neizvi, mabhesi akagadzirwa nezvimwe zvinhu anogona kukonzera shanduko mukuiswa kwemidziyo nekuda kwekusakara, nokudaro zvichikanganisa kunyatsoonekwa kwayo uye zvinoda kuongororwa nguva nenguva. Nguva refu yebasa uye kugadzikana kwakanyanya kwechigadziko chegranite zvinoderedza nguva yekuchengetedzwa kwemidziyo uye kuderedza njodzi yekurasikirwa nekururama kunogona kuitika panguva yekugadzirisa.
Kubva pakusagadzikana, kusadzivirirwa pakupisa kusvika pakugadzirwa kwakarurama, chinhu chega chega chiri pachigadziko chegranite chiri kuchengetedza kururama kwekuyedzwa kwewafers kusingaparadze. Munguva ino yekugadzira semiconductor inotsvaga kunyatsojeka, kusarudza chigadziko chegranite chemhando yepamusoro kwakafanana nekuwedzera jira rakasimba reinishuwarenzi kune kururama uye kuvimbika kwemhedzisiro yebvunzo.
