Zigawo za granite zakhala zikugwiritsidwa ntchito kwambiri popanga zinthu za semiconductor chifukwa cha makhalidwe awo abwino kwambiri monga kutsirizika bwino kwa pamwamba, kuuma kwambiri, komanso kugwedezeka bwino kwa vibration. Zigawo za granite ndizofunikira kwambiri pazida zopangira zinthu za semiconductor, kuphatikizapo makina a lithography, makina opukuta, ndi machitidwe a metrology chifukwa zimapereka malo olondola komanso kukhazikika panthawi yopanga. Ngakhale zabwino zonse zogwiritsa ntchito zigawo za granite, zilinso ndi zolakwika. M'nkhaniyi, tikambirana za zolakwika za zigawo za granite pazinthu zopangira zinthu za semiconductor.
Choyamba, zigawo za granite zimakhala ndi kuchuluka kwa kutentha komwe kumawonjezeka. Izi zikutanthauza kuti zimakula kwambiri chifukwa cha kutentha kwambiri, zomwe zingayambitse mavuto panthawi yopanga. Njira yopangira ma semiconductor imafuna kulondola kwakukulu komanso kulondola kwa magawo komwe kungasokoneze chifukwa cha kutentha kwambiri. Mwachitsanzo, kusintha kwa silicon wafer chifukwa cha kutentha kwambiri kungayambitse mavuto olumikizana panthawi ya lithography, zomwe zingasokoneze mtundu wa chipangizo cha semiconductor.
Chachiwiri, zigawo za granite zili ndi zolakwika za porosity zomwe zingayambitse kutuluka kwa vacuum mu njira yopangira semiconductor. Kupezeka kwa mpweya kapena mpweya wina uliwonse mu dongosolo kungayambitse kuipitsidwa pamwamba pa wafer, zomwe zimapangitsa kuti pakhale zolakwika zomwe zingakhudze magwiridwe antchito a chipangizo cha semiconductor. Mipweya yopanda kanthu monga argon ndi helium imatha kulowa mu zigawo za granite zokhala ndi porosity ndikupanga thovu la mpweya lomwe lingasokoneze kukhulupirika kwa njira yotulutsira vacuum.
Chachitatu, zigawo za granite zimakhala ndi ma fractures ang'onoang'ono omwe angasokoneze kulondola kwa njira yopangira. Granite ndi chinthu chophwanyika chomwe chingapangitse ma fractures ang'onoang'ono pakapita nthawi, makamaka ngati chikukumana ndi zovuta nthawi zonse. Kupezeka kwa ma fractures ang'onoang'ono kungayambitse kusakhazikika kwa mawonekedwe, zomwe zimayambitsa mavuto akuluakulu panthawi yopanga, monga lithography alignment kapena wafer polishing.
Chachinayi, zigawo za granite zimakhala ndi kusinthasintha kochepa. Njira yopangira zinthu za semiconductor imafuna zida zosinthika zomwe zingathandize kusintha kwa njira zosiyanasiyana. Komabe, zigawo za granite zimakhala zolimba ndipo sizingasinthe kusintha kwa njira zosiyanasiyana. Chifukwa chake, kusintha kulikonse pakupanga kumafuna kuchotsa kapena kusintha zigawo za granite, zomwe zimapangitsa kuti ntchito isamayende bwino komanso kukhudza kupanga bwino.
Chachisanu, zigawo za granite zimafunika kusamalidwa mwapadera komanso kunyamulidwa mwapadera chifukwa cha kulemera kwawo komanso kufooka kwawo. Granite ndi chinthu cholemera komanso cholemera chomwe chimafuna zida zapadera zogwirira ntchito monga ma crane ndi zonyamulira. Kuphatikiza apo, zigawo za granite zimafunika kulongedza mosamala ndi kunyamulidwa kuti zisawonongeke panthawi yotumiza, zomwe zimapangitsa kuti pakhale ndalama zowonjezera komanso nthawi yowonjezera.
Pomaliza, zigawo za granite zili ndi zovuta zina zomwe zingakhudze ubwino ndi kupanga kwa zinthu zopangira semiconductor. Zofooka izi zitha kuchepetsedwa mwa kusamalira mosamala ndi kusamalira zigawo za granite, kuphatikizapo kuyang'ana nthawi ndi nthawi kuti mudziwe ngati pali zofooka zazing'ono komanso zofooka za porosity, kuyeretsa bwino kuti mupewe kuipitsidwa, komanso kusamalira mosamala panthawi yoyendera. Ngakhale kuti pali zofooka, zigawo za granite zimakhalabe gawo lofunika kwambiri pakupanga semiconductor chifukwa cha kukongola kwake pamwamba, kuuma kwake, komanso kugwedezeka bwino.
