Zigawo za granite zimagwiritsidwa ntchito kwambiri mu zida za semiconductor chifukwa cha kukhazikika kwawo kwakukulu komanso kulimba. Zimayang'anira kusunga kulondola ndi kulondola kwa njira zopangira semiconductor. Komabe, kugwira ntchito bwino ndi kudalirika kwa zigawo za granite kumadalira miyezo ndi zofunikira zomwe zimatsatiridwa popanga, kupanga, ndi kukhazikitsa.
Izi ndi zina mwa miyezo ndi zofunikira zomwe ziyenera kutsatiridwa mukamagwiritsa ntchito zigawo za granite mu zida za semiconductor:
1. Kuchuluka kwa Zinthu: Kuchuluka kwa zinthu za granite zomwe zimagwiritsidwa ntchito popanga zinthu za granite kuyenera kukhala pafupifupi 2.65g/cm3. Uku ndi kuchuluka kwa zinthu zachilengedwe za granite, ndipo kumatsimikizira kuti zinthu za granite zimakhala zogwirizana komanso zodalirika.
2. Kusalala: Kusalala ndi chimodzi mwa zinthu zofunika kwambiri pa zigawo za granite zomwe zimagwiritsidwa ntchito mu zida za semiconductor. Kusalala kwa pamwamba pa granite kuyenera kukhala pansi pa 0.001 mm/m2. Izi zimatsimikizira kuti pamwamba pa gawoli ndi lathyathyathya komanso losalala, zomwe ndizofunikira kwambiri popanga zinthu za semiconductor.
3. Kumaliza Pamwamba: Kumaliza pamwamba pa zigawo za granite kuyenera kukhala kwapamwamba kwambiri, ndi kukhwima pansi pa 0.4µm. Izi zimatsimikizira kuti pamwamba pa gawo la granite pali kupsinjika kochepa, komwe ndikofunikira kwambiri kuti zida za semiconductor zigwire ntchito bwino.
4. Kuchuluka kwa Kutentha: Zipangizo za semiconductor zimagwira ntchito pa kutentha kosiyanasiyana, ndipo zigawo za granite ziyenera kukhala zokhoza kupirira kusinthasintha kwa kutentha popanda kusintha. Kuchuluka kwa kutentha kwa granite komwe kumagwiritsidwa ntchito mu zida za semiconductor kuyenera kukhala pansi pa 2 x 10^-6 /°C.
5. Kulekerera kwa Miyeso: Kulekerera kwa miyeso n'kofunika kwambiri kuti zigawo za granite zigwire ntchito bwino. Kulekerera kwa miyeso kwa zigawo za granite kuyenera kukhala mkati mwa ± 0.1mm pa miyeso yonse yofunika.
6. Kulimba ndi Kukana Kuvala: Kulimba ndi kukana kuvala ndizofunikira kwambiri pazinthu za granite zomwe zimagwiritsidwa ntchito mu zida za semiconductor. Granite ili ndi kuuma kwa Mohs Scale 6-7, zomwe zimapangitsa kuti ikhale chinthu choyenera kugwiritsidwa ntchito pazida za semiconductor.
7. Kugwira Ntchito kwa Chitsulo Choteteza: Zigawo za granite zomwe zimagwiritsidwa ntchito mu zida za semiconductor ziyenera kukhala ndi ntchito yabwino kwambiri yoteteza kuti zisawonongeke ndi zigawo zamagetsi zomwe zimakhala zovuta kuziteteza. Kukana kwa magetsi kuyenera kukhala pamwamba pa 10^9 Ω/cm.
8. Kukana Mankhwala: Zigawo za granite ziyenera kukhala zosagwirizana ndi mankhwala wamba omwe amagwiritsidwa ntchito popanga zinthu za semiconductor, monga ma acid ndi alkali.
Pomaliza, miyezo ndi zofunikira za zigawo za granite zomwe zimagwiritsidwa ntchito mu zida za semiconductor ndizofunikira kwambiri kuti zitsimikizire kuti zigawo zonse ziwiri ndi zida zomwe zimagwiritsidwa ntchito zimakhala ndi moyo wautali komanso wodalirika. Malangizo omwe ali pamwambapa ayenera kutsatiridwa mosamala popanga, kupanga, ndi kukhazikitsa kuti zitsimikizire kuti zigawozo ndi zapamwamba kwambiri. Potsatira miyezo ndi zofunikirazi, opanga zida za semiconductor amatha kuwonetsetsa kuti magwiridwe antchito a zida zawo akupitilizabe kukhala abwino, zomwe zimapangitsa kuti pakhale zokolola zambiri komanso phindu.
