Bedi la granite ndi chimodzi mwa zinthu zomwe zimagwiritsidwa ntchito kwambiri popanga zida za semiconductor zolondola kwambiri. Ndi mwala womwe umapangidwa ndi magma yomwe imapangika pang'onopang'ono komanso yolimba mkati mwa nthaka. Chinthu chachikulu cha granite ndichakuti ndi chinthu cholimba, chokhuthala, komanso cholimba, zomwe zimapangitsa kuti chigwiritsidwe ntchito bwino popanga maziko ndi mabedi a makina.
Zigawo zazikulu za bedi la granite ndi feldspar, quartz, ndi mica. Feldspar ndi gulu la mchere wopangira miyala womwe umapezeka kwambiri mu granite. Ndi mchere wochuluka kwambiri mu granite, ndipo kupezeka kwake mumwala kumapangitsa kuti ukhale wosalala. Quartz ndi mchere wina womwe umapezeka kwambiri mu granite. Ndi mchere wolimba komanso wofooka womwe umatha kupirira kutentha kwambiri, zomwe zimapangitsa kuti ugwiritsidwe ntchito bwino kwambiri. Koma Mica, kumbali ina, ndi mchere wofewa womwe umapanga zidutswa zoonda komanso zosinthasintha. Kupezeka kwake mu granite kumathandiza kuti pakhale bata komanso kupewa ming'alu.
Kugwiritsa ntchito bedi la granite mu zipangizo za semiconductor kuli ndi ubwino wambiri. Choyamba, kumapereka malo okhazikika komanso athyathyathya kuti wafer ya semiconductor ikhalepo. Izi, zimathandiza kuti pakhale njira zodziwikiratu zopangira chifukwa kusintha pang'ono kapena kusintha kulikonse pamwamba pa bedi kungayambitse zolakwika kapena zolakwika mu chipangizo cha semiconductor. Kulimba kwa bedi la granite kumatanthauzanso kuti silingathe kuwonongeka kapena kusokonekera pakapita nthawi, zomwe zimapangitsa kuti zida zizikhala zolimba nthawi zonse.
Ubwino wina wogwiritsa ntchito bedi la granite mu zida za semiconductor ndikuti lili ndi coefficient yotsika ya kutentha. Izi zikutanthauza kuti limatha kupirira kusintha kwa kutentha popanda kukhudza magwiridwe antchito a chipangizo cha semiconductor. Motero, opanga ma semiconductor amatha kuchita zinthu zomwe zimafuna kutentha kwambiri popanda kuda nkhawa ndi kukula kwa kutentha kapena kuchepa. Kuphatikiza apo, zimaletsa kukula kwa kutentha, komwe kungawononge magwiridwe antchito a zida.
Mapeto
Pomaliza, kugwiritsa ntchito bedi la granite mu zida za semiconductor kwasintha makampani, zomwe zapangitsa kuti pakhale zida zogwira mtima komanso zolondola. Zigawo zazikulu za bedi la granite, kuphatikizapo feldspar, quartz, ndi mica, zimaonetsetsa kuti bedi ndi lolimba, lokhazikika, komanso lili ndi kutentha kochepa. Izi zimapangitsa kuti likhale labwino kwambiri popanga makina omwe amafunikira kulondola kwambiri, monga omwe amagwiritsidwa ntchito popanga zida za semiconductor. Kugwiritsa ntchito bedi la granite kudzapitirira kukhala gawo lofunikira kwa zaka zambiri zikubwerazi, pamene opanga akuyesetsa kupanga zida zapamwamba kwambiri za semiconductor.
