Kwidabi lokugqibela "lokuchaneka kwe-nanoprecision" kwimveliso ye-semiconductor, nokuba yimpazamo encinci kwizixhobo zokusika i-wafer inokuguqula itshiphu ibe yinkunkuma. Isiseko segranite liqhawe elingadunyiswanga elilawula ukuchaneka kokubeka indawo okuphindaphindwayo kwe-±5um, libhala ngokutsha imithetho yokuvelisa ngokuchanekileyo ngemimangaliso yalo emithathu yendalo.
"I-anchor yokuzinzisa" ngokuchasene nokuguquguquka kobushushu: I-coefficient yokwandiswa kobushushu begranite iphantsi njenge-5-7 × 10⁻⁶/℃, eyi-1/3 kuphela yezixhobo zesinyithi. Phantsi kwempembelelo yobushushu eveliswa kukusebenza ngesantya esiphezulu kwezixhobo zokusika i-wafer, izixhobo eziqhelekileyo ziya kuguquka ngenxa yokwanda kobushushu kunye nokucutheka, okubangela ukuba intloko yokusika itshintshe. Nangona kunjalo, isiseko segranite sinokuhlala "singanyakazi", ngokusisiseko sisuse ukuphambuka kwendawo okubangelwa kukuguquguquka kobushushu kwaye sibeke isiseko esiqinileyo sokuchaneka.
"Isikhuselo esithuleyo" sokufunxa ukungcangcazela: Ukugquma okuqhubekayo kwezixhobo zoomatshini kunye nokungcangcazela okuqhubekayo kwezixhobo kwindawo yokusebenzela kunokubonwa "njengezibulali ezibulalayo" ngokuchanekileyo. Ulwakhiwo olukhethekileyo lwekristale yegranite lufana nesixhobo sokufunxa ukungcangcazela kwendalo, esikwaziyo ukuguqula ngokukhawuleza ukungcangcazela kwangaphandle kunye nokungcangcazela koomatshini okuveliswa kukusebenza kwezixhobo zibe ngamandla obushushu ukuze kutshatyalaliswe. Ngelixa ezinye iziseko "zisashukuma" ngenxa yokungcangcazela, isiseko segranite senze iqonga elizinzileyo lentloko yokusika elihlala lingashukumi, okwenza ukuchaneka kwe-±5um kube nokwenzeka.
"Inqaba Engunaphakade" Engamelani Nokugqwala: Iiworkshop ze-semiconductor zizaliswe zizinto ezigqwala ezifana nezisombululo zokugqwala kunye nezicoci ze-asidi kunye ne-alkali. Kwimeko enjalo, iziseko zesinyithi ziya kugqwala kwaye ziguquguquke kancinci kancinci. I-granite, ngenxa yokuzinza kwayo ngokweekhemikhali, ayisabelani nalezi zinto zeekhemikhali konke konke. Nokuba isetyenziswa iminyaka emingaphi, inokugcina ukuqina kwesakhiwo kwaye iqinisekise ukunqunyulwa okuchanekileyo rhoqo.
Ukususela kwitalente yezinto ezibonakalayo ukuya ekucutshungulweni okuchanekileyo kakhulu, isiseko segranite sibonakalise ngamandla aso ukuba ayizizo zonke izinto ezinokuhlangabezana nemingeni enzima yokwenziwa kwee-semiconductor. Kungenxa yezi nzuzo zendalo ezingenakutshintshwa ukuba iziseko zegranite zibe ngundoqo kwizixhobo zokusika ii-wafer ukuze kufezekiswe ukuchaneka kokubekwa okuphindaphindiweyo kwe-±5um, kwaye ziqhubele phambili ishishini le-semiconductor ukuba liqhubeke lisiya ngokuchanekileyo okuphezulu!
