Zigawo za granite zakhala zikugwiritsidwa ntchito kwambiri popanga semiconductor chifukwa cha mawonekedwe awo abwino kwambiri monga kumaliza kwapamwamba, kuuma kwakukulu, komanso kugwetsa kwamphamvu kwambiri.Zida za granite ndizofunikira pazida zopangira semiconductor, kuphatikiza makina a lithography, makina opukutira, ndi makina a metrology popeza amapereka malo olondola komanso okhazikika panthawi yopanga.Ngakhale zabwino zonse zogwiritsira ntchito zida za granite, amakhalanso ndi zolakwika.M'nkhaniyi, tikambirana zolakwika za zida za granite pakupanga zinthu za semiconductor.
Choyamba, zigawo za granite zimakhala ndi mphamvu yowonjezera yowonjezera kutentha.Zimatanthawuza kuti amakula kwambiri pansi pa kupsinjika kwa kutentha, zomwe zingayambitse mavuto panthawi yopanga.Njira yopangira semiconductor imafuna kulondola kwambiri komanso kulondola kwapang'onopang'ono komwe kungasokonezedwe chifukwa cha kupsinjika kwamafuta.Mwachitsanzo, kusinthika kwa silicon wafer chifukwa chakukula kwa matenthedwe kumatha kuyambitsa zovuta zamalumikizidwe panthawi ya lithography, zomwe zitha kusokoneza mtundu wa chipangizo cha semiconductor.
Chachiwiri, zida za granite zimakhala ndi zolakwika za porosity zomwe zingayambitse kutayikira kwa vacuum popanga semiconductor.Kukhalapo kwa mpweya kapena mpweya wina uliwonse m'dongosololi ukhoza kuyambitsa kuipitsidwa pamwamba pa chophikacho, zomwe zimapangitsa kuti pakhale zolakwika zomwe zingasokoneze magwiridwe antchito a chipangizo cha semiconductor.Mipweya ya inert monga argon ndi helium imatha kulowa m'zigawo za porous granite ndikupanga thovu la gasi lomwe lingasokoneze kukhulupirika kwa vacuum.
Chachitatu, zigawo za granite zimakhala ndi ma microfractures omwe angasokoneze kulondola kwa kupanga.Granite ndi chinthu chophwanyika chomwe chimatha kupanga ma microfractures pakapita nthawi, makamaka akakumana ndi kupsinjika kosalekeza.Kukhalapo kwa ma microfractures kumatha kubweretsa kusakhazikika, zomwe zimapangitsa kuti pakhale zovuta kwambiri panthawi yopanga, monga kuyika kwa lithography kapena kupukuta kwawafa.
Chachinayi, zigawo za granite zimakhala ndi kusinthasintha kochepa.Njira yopangira semiconductor imafuna zida zosinthika zomwe zitha kutengera kusintha kwamachitidwe osiyanasiyana.Komabe, zigawo za granite ndizolimba ndipo sizingagwirizane ndi kusintha kosiyanasiyana.Choncho, kusintha kulikonse pakupanga kumafuna kuchotsedwa kapena kusinthidwa kwa zigawo za granite, zomwe zimapangitsa kuti pakhale nthawi yopuma komanso kusokoneza zokolola.
Chachisanu, zigawo za granite zimafuna kuchitidwa mwapadera ndi zoyendetsa chifukwa cha kulemera kwake ndi kufooka.Granite ndi chinthu cholimba komanso cholemera chomwe chimafunikira zida zapadera zogwirira ntchito monga ma crane ndi zonyamula.Kuphatikiza apo, zida za granite zimafunikira kulongedza mosamala ndikuyendetsa kuti zisawonongeke panthawi yotumiza, zomwe zimapangitsa kuti pakhale ndalama zowonjezera komanso nthawi.
Pomaliza, zida za granite zili ndi zovuta zina zomwe zingakhudze mtundu wa zinthu zopangira semiconductor ndi zokolola.Zowonongekazi zitha kuchepetsedwa posamalira ndikusamalira mosamala zida za granite, kuphatikiza kuyang'ana pafupipafupi ma microfractures ndi kuwonongeka kwa porosity, kuyeretsa bwino kuti zisaipitsidwe, komanso kusamalitsa mosamala panthawi yamayendedwe.Ngakhale zili zolakwika, zida za granite zimakhalabe gawo lofunikira kwambiri popanga semiconductor chifukwa cha kutha kwake kwapamwamba, kuuma kwakukulu, komanso kugwedera kwabwino kwambiri.
