Kusintha kolondola pakudula kwawafer! Momwe mungasungire malo a ± 5um pamaziko a granite?

Pankhondo yomaliza ya "nanoprecision" pakupanga semiconductor, ngakhale cholakwika pang'ono pazida zodulira zophatikizika zimatha kusintha chip kukhala zinyalala. Maziko a granite ndi ngwazi yosadziwika bwino yomwe imawongolera kulondola kwa ± 5um kubwereza, ndikulembanso malamulo opangira molondola ndi zodabwitsa zake zitatu zachilengedwe.

"Nangula wokhazikika" motsutsana ndi kusinthika kwamafuta: Coefficient of thermal expansion of granite ndi yotsika ngati 5-7 × 10⁻⁶/℃, yomwe ndi gawo limodzi mwa magawo atatu a zida zachitsulo. Pansi pa kutentha komwe kumapangidwa ndi ntchito yothamanga kwambiri ya zida zodulira zophatikizika, zida wamba zimapunduka chifukwa chakukula kwamafuta ndi kutsika, zomwe zimapangitsa kuti mutu wodulira usinthe. Komabe, maziko a granite amatha kukhala "osasunthika", ndikuchotsa kupotoza komwe kumadza chifukwa cha kusinthika kwamafuta ndikuyika maziko olimba olondola.

"Chishango chopanda phokoso" cha kuyamwa kwa vibration: Kubangula kosalekeza kwa zida zamakina komanso kugwedezeka kosalekeza kwa zida zomwe zili mumsonkhanowu zitha kuwonedwa ngati "akupha akupha" molondola. Mapangidwe apadera a kristalo a granite ali ngati chotsitsa chachilengedwe, chomwe chimatha kutembenuza mwachangu kugwedezeka kwakunja ndi kugwedezeka kwamakina komwe kumapangidwa ndi zida zogwirira ntchito kukhala mphamvu yotentha kuti iwonongeke. Ngakhale maziko ena akadali "akugwedezeka" chifukwa cha kugwedezeka, maziko a granite apanga nsanja yokhazikika ya mutu wodula yomwe imakhala yosasunthika, kupanga ± 5um kulondola.

Zosagwirizana ndi dzimbiri "Linga Lamuyaya" : Zokambirana za semiconductor zimadzaza ndi zinthu zowononga monga etching solutions and acid and alkali cleaners. M'malo oterowo, maziko achitsulo amatha dzimbiri pang'onopang'ono ndikupunduka. Granite, yokhala ndi kukhazikika kwake kwachilengedwe, sichimakhudzidwa ndi zinthu izi. Ziribe kanthu zaka zingati zomwe zimagwiritsidwa ntchito, zimatha kusunga umphumphu wamapangidwe ndikuonetsetsa kuti kudula kolondola kwambiri.

Kuchokera ku talente yakuthupi kupita ku kukonza kolondola kwambiri, maziko a granite awonetsa ndi mphamvu zake kuti sizinthu zonse zomwe zimatha kuthana ndi zovuta zopanga semiconductor. Ndi chifukwa cha zabwino zomwe sizingalowe m'malo mwachilengedwe kuti maziko a granite akhala chinsinsi cha zida zodulira zopindika kuti akwaniritse kubwereza kolondola kwa ± 5um, ndipo zachititsanso kuti makampani opanga zida zopangira zida zamagetsi azisunthira mosalekeza kulondola kwambiri!
