A fannoni kamar kera guntu da auna daidaito, halayen kayan aiki kai tsaye suna tantance daidaiton kayan aiki. Granite, tare da halaye guda biyar na asali, ya bambanta da kayan aiki kamar ƙarfe, robobi na injiniya da yumbu, kuma ya zama "abokin tarayya na zinare" na kayan aiki masu inganci.
1. Daidaiton zafi: "Gyaran jiki" zuwa canjin yanayin zafi
Ga kowace canjin zafin jiki na 1℃, bakin karfe yana faɗaɗa da 17μm/m, ƙarfen aluminum yana faɗaɗa da 23μm/m, yayin da granite yana faɗaɗa da 4-8μm/m. A masana'antun semiconductor, yawan zafin da ake samu ta hanyar amfani da injunan photolithography ko bambancin zafin jiki tsakanin farawa da tsayawa na na'urorin sanyaya iska yana da kusan tasiri kaɗan akan girman granite. Sabanin haka, nakasar ƙarfe da robobi saboda faɗaɗa zafi da matsewa na iya haifar da rashin daidaiton abubuwan da aka gyara cikin sauƙi.
2. Juriyar Girgiza: "Mai lalata" kuzarin girgiza
Granite yana da yawan danshi mai yawa (2.6-3.1g/cm³), tauri na 6-7 akan sikelin Mohs, da kuma rabon damping sau 5-10 na bakin karfe. A cikin kayan aunawa daidai, yana iya rage kashi 90% na kuzarin girgiza cikin daƙiƙa 0.5, yayin da kayan ƙarfe ke buƙatar daƙiƙa 3 zuwa 5. Girgizar da aka samu ta hanyar aikin kayan aiki da motsin ma'aikata a cikin bitar yana da wuya a girgiza kwanciyar hankalin kayan aikin da granite ke tallafawa.
3. Daidaiton sinadarai: "Mai taurin kai" a cikin muhallin acidic da alkaline
Idan aka jiƙa granite a cikin wani maganin acid mai ƙarfi (pH=2) ko maganin alkali mai ƙarfi (pH=12) na tsawon awanni 1000, adadin tsatsa a saman ƙasa da 0.01μm. Bakin ƙarfe yana da saurin tsatsa ta hanyar acid da alkalis, ƙarfen aluminum yana tsoron abubuwan alkaline, kuma robobi na injiniya za su kumbura lokacin da aka fallasa su ga sinadarai masu narkewa. Tsarin granite mai yawa (porosity < 0.1%) kuma zai iya hana gurɓatar barbashi, wanda hakan ya sa ya zama "kayan da aka zaɓa" don tsaftace ɗakunan semiconductor.
4. Sarrafawa da Kuɗi: "Mai Girman Daidaito" tsakanin Daidaito da Aikin Kuɗi
Ana iya niƙa dutse mai siffar ≤0.5μm/m da kuma taurin saman Ra na ≤0.05μm, amma sarrafa shi yana ɗaukar lokaci mai tsawo. Bakin ƙarfe yana da sauƙin sarrafawa amma yana iya lalacewa, yayin da yumbu ke da daidaito mai yawa amma yana da tsada. A cikin yanayin da ke bin daidaiton nanoscale, cikakken aikin farashin granite ya fi na sauran kayan aiki.
5. Tsarkakakken Wutar Lantarki: "Mai Tsaftace" Na'urorin Lantarki
A matsayinsa na abu mara ƙarfe, granite ba shi da maganadisu kuma ba ya daɗaɗawa, kuma ba zai tsoma baki ga na'urori masu auna sigina da abubuwan lantarki ba. Ƙarfin wutar lantarki da maganadisu na ƙarfe, wutar lantarki mai ƙarfi ta robobi na injiniya, da asarar dielectric na yumbu duk suna zama "masu rauni" idan aka yi la'akari da kayan aiki masu inganci kamar na'urorin photolithography da na'urorin maganadisu na nukiliya. Duk da haka, granite ya dace sosai da muhallin da ke da saurin amsawa ga lantarki.
Daga juriyar zafi mai yawa zuwa juriyar girgiza, daga hana tsatsa zuwa tsangwama ta hanyar lantarki, dutse ya tabbatar da cewa a fannin kera kayayyaki daidai, shine "sarki" da ba za a iya maye gurbinsa ba.
