Ubwino wosankha maziko a granite patebulo loyesera la semiconductor wafer.

​
Mu makampani opanga ma semiconductor, kuwunika ma wafer ndi njira yofunika kwambiri yotsimikizira kuti chip ndi yabwino komanso ikugwira ntchito bwino, ndipo kulondola ndi kukhazikika kwa tebulo lowunikira kumachita gawo lofunika kwambiri pakupeza zotsatira. Maziko a granite okhala ndi mawonekedwe ake apadera, amakhala chisankho chabwino kwambiri patebulo lowunikira ma wafer a semiconductor, izi kuchokera ku kusanthula kwamitundu yambiri kwa inu.

Choyamba, gawo la chitsimikizo cholondola
1. Kusalala ndi kulunjika kwakukulu: Maziko a granite amakonzedwa pogwiritsa ntchito ukadaulo wapamwamba wopangira, ndipo kusalala kumatha kufika ± 0.001mm/m kapena kulondola kwambiri, ndipo kulunjikako kumakhala kwabwino kwambiri. Mu ndondomeko yowunikira wafer, malo olondola kwambiri amapereka chithandizo chokhazikika cha wafer ndikuwonetsetsa kuti chofufuzira cha zida zowunikira ndi malo olumikizirana pamwamba pa wafer zikugwirizana molondola.
2. Kuchuluka kwa kutentha kochepa kwambiri: kupanga ma semiconductor kumakhudzidwa ndi kusintha kwa kutentha, ndipo kuchuluka kwa kutentha kwa granite kumakhala kochepa kwambiri, nthawi zambiri pafupifupi 5×10⁻⁶/℃. Pamene nsanja yozindikira ikugwira ntchito, ngakhale kutentha kwa malo ozungulira kusinthasintha, kukula kwa maziko a granite sikusintha kwenikweni. Mwachitsanzo, mu malo ochitira masewera olimbitsa thupi otentha kwambiri m'chilimwe, kutentha kwa nsanja yodziwira maziko achitsulo wamba kungayambitse malo ofanana a wafer ndi zida zodziwira kusuntha, zomwe zimakhudza kulondola kwa kuzindikira; Nsanja yodziwira maziko a granite imatha kusunga kukhazikika, kuonetsetsa kulondola kwa malo ofanana a wafer ndi zida zodziwira panthawi yozindikira, ndikupereka malo okhazikika odziwira molondola kwambiri.
Chachiwiri, gawo lokhazikika
1. Kapangidwe kokhazikika ndi kukana kugwedezeka: Granite pambuyo pa zaka mamiliyoni ambiri za njira za geological, kapangidwe ka mkati kamakhala kokhuthala komanso kofanana. Mu malo ovuta a fakitale ya semiconductor, kugwedezeka komwe kumachitika chifukwa cha kugwiritsa ntchito zida zozungulira ndi antchito oyendayenda kumachepetsedwa bwino ndi maziko a granite.
2. Kulondola kwa kugwiritsa ntchito kwa nthawi yayitali: poyerekeza ndi zipangizo zina, granite ili ndi kuuma kwakukulu, kukana kuvala kwambiri, ndipo kuuma kwa Mohs kumatha kufika 6-7. Malo oyambira a granite savalidwa mosavuta panthawi yodzaza, kutsitsa ndi kuyang'anira nthawi zambiri. Malinga ndi momwe ziwerengero za deta zimagwiritsidwira ntchito, kugwiritsa ntchito tebulo loyesera maziko a granite, kugwira ntchito kosalekeza pambuyo pa maola 5000, kulondola kwa kusalala ndi kulunjika kumatha kusungidwabe pamlingo woposa 98% wa kulondola koyambirira, kuchepetsa zida chifukwa cha kuvala kwa maziko komwe kumachitika chifukwa cha nthawi yowunikira nthawi zonse ndi nthawi yokonza, kuchepetsa ndalama zogwirira ntchito zamabizinesi, kuti zitsimikizire kukhazikika kwa ntchito yoyesa kwa nthawi yayitali.

Chachitatu, gawo loyera komanso loletsa kusokonezedwa
1. Kupanga fumbi lochepa: malo opangira ma semiconductor ayenera kukhala oyera kwambiri, ndipo granite yokha ndi yokhazikika komanso yosavuta kupanga tinthu ta fumbi. Pakagwiritsidwa ntchito nsanja yoyesera, fumbi lopangidwa ndi maziko limapewa kuipitsa wafer, ndipo chiopsezo cha short circuit ndi open circuit chifukwa cha tinthu ta fumbi chimachepa. M'dera loyang'anira wafer la malo ogwirira ntchito opanda fumbi, kuchuluka kwa fumbi kuzungulira tebulo loyang'anira maziko a granite nthawi zonse kumawongoleredwa mpaka pamlingo wotsika kwambiri, kukwaniritsa zofunikira zaukhondo wa makampani opanga ma semiconductor.
2. Palibe kusokoneza kwa maginito: zida zozindikira zimakhala zokhudzidwa ndi malo amagetsi, ndipo granite ndi chinthu chosakhala ndi maginito, chomwe sichingasokoneze chizindikiro chamagetsi cha zida zozindikira. Pogwiritsa ntchito njira zozindikira kuwala kwa ma elekitironi ndi ukadaulo wina woyesera womwe umafuna malo okwera kwambiri amagetsi, maziko a granite amatsimikizira kutumiza kokhazikika kwa chizindikiro chamagetsi cha zida zozindikira ndikutsimikizira kulondola kwa zotsatira za mayeso. Mwachitsanzo, pamene wafer imayesedwa kuti igwire bwino ntchito yamagetsi, maziko a granite osakhala ndi maginito amapewa kusokoneza zizindikiro zamagetsi ndi magetsi, kotero kuti deta yozindikira ikuwonetsadi mawonekedwe amagetsi a wafer.
