Kusintha kwakukulu pakudula bwino kwa wafer! Kodi mungasunge bwanji malo a ±5um pa maziko a granite?

Mu nkhondo yomaliza ya "nanoprecision" popanga zinthu za semiconductor, ngakhale cholakwika chochepa kwambiri pazida zodulira wafer chingapangitse chip kukhala zinyalala. Maziko a granite ndi ngwazi yosayamikiridwa yomwe imalamulira kulondola kwa ±5um mobwerezabwereza, ndikulembanso malamulo opangira molondola ndi zodabwitsa zake zitatu zachilengedwe.

"Nangula wokhazikika" motsutsana ndi kusintha kwa kutentha: Kuchuluka kwa kutentha kwa granite kumakhala kotsika kufika pa 5-7 × 10⁻⁶/℃, komwe ndi gawo limodzi mwa magawo atatu okha a zinthu zachitsulo. Pansi pa kutentha komwe kumachitika chifukwa cha kugwira ntchito mwachangu kwa zida zodulira wafer, zinthu wamba zimasokonekera chifukwa cha kufalikira kwa kutentha ndi kupindika, zomwe zimapangitsa kuti mutu wodulira usunthike. Komabe, maziko a granite amatha kukhalabe "osasunthika", kuchotsa kusintha kwa malo komwe kumachitika chifukwa cha kusintha kwa kutentha ndikukhazikitsa maziko olimba kuti akhale olondola.

"Chishango chopanda phokoso" cha kuyamwa kwa kugwedezeka: Kugwedezeka kosalekeza kwa zida zamakina ndi kugwedezeka kosalekeza kwa zida mu workshop kungawonedwe ngati "zakupha" kukhala zolondola. Kapangidwe kapadera ka granite kamafanana ndi choyamwa chachilengedwe chachilengedwe, chomwe chimatha kusintha mwachangu kugwedezeka kwakunja ndi kugwedezeka kwamakina komwe kumachitika chifukwa cha kugwiritsa ntchito zida kukhala mphamvu yotentha kuti ziwonongeke. Ngakhale maziko ena akadali "ogwedezeka" chifukwa cha kugwedezeka, maziko a granite apanga nsanja yokhazikika ya mutu wodula womwe umakhalabe wosasuntha, zomwe zimapangitsa kuti kulondola kwa ±5um kutheke.

"Eternal Fortress" yosagonjetsedwa ndi dzimbiri: Ma workshop a semiconductors amadzaza ndi zinthu zowononga monga njira zoyeretsera ndi zotsukira za asidi ndi alkali. M'malo otere, maziko achitsulo amayamba dzimbiri pang'onopang'ono. Granite, yokhala ndi kukhazikika kwa mankhwala, sichitapo kanthu ndi zinthu izi. Kaya igwiritsidwe ntchito kwa zaka zingati, imatha kusunga mawonekedwe ake ndikuwonetsetsa kuti imadulidwa bwino nthawi zonse.

Kuyambira pa luso la zinthu mpaka kukonza zinthu molondola kwambiri, maziko a granite awonetsa ndi mphamvu zake kuti si zipangizo zonse zomwe zingakumane ndi mavuto aakulu opanga zinthu za semiconductor. Chifukwa cha ubwino wachilengedwe wosasinthikawu, maziko a granite akhala chinsinsi cha zida zodulira wafer kuti zikwaniritse kulondola kobwerezabwereza kwa ±5um, ndipo zapangitsa makampani opanga zinthu za semiconductor kuti apitirizebe kulondola kwambiri!
