Kwimizi-mveliso efana nee-semiconductors kunye ne-electronics echanekileyo, eneemfuno ezingqongqo kakhulu kwimeko yemveliso, ukucoceka kwendawo yokusebenzela engenaluthuli kuchaphazela ngokuthe ngqo izinga lemveliso. Ingxaki yongcoliseko ebangelwa kukugqwala kweziseko zesinyithi zemveli iba yingxaki enzima kumashishini. Nangona kunjalo, isisombululo se-granite se-ZHHIMG siphumelele ngempumelelo isiqinisekiso esigunyazisiweyo ngokusebenza kwaso okugqwesileyo, nto leyo ezisa impumelelo entsha kushishino.
Nangona iziseko zesinyithi eziphosiweyo zisetyenziswa kakhulu kwicandelo lemizi-mveliso, ukumelana kwazo nokugqwala okubi kubonakala ngokupheleleyo kwindawo yokusebenzela engenathuli. Isinyithi esiphosiweyo senziwe kakhulu yintsimbi kunye nekhabhoni, kwaye sithambekele kakhulu kwiimpendulo ze-oxidation kunye neoksijini kunye nokufuma emoyeni, okwenza umhlwa. Kwindawo yokusebenzela engenathuli, nokuba umhlwa omncinci ophumayo unokuvelisa iifayili zesinyithi. Nje ukuba ezi nxalenye zingene kwizixhobo ezichanekileyo okanye zinamathele kumphezulu weemveliso, zinokubangela iziphumo ezibi ezifana neesekethe ezimfutshane kwiitships ze-semiconductor kunye nongcoliseko lwezinto ezibonakalayo ezichanekileyo, nto leyo enyusa kakhulu izinga leziphene zeemveliso. Ngokwezibalo zoshishino, iingxaki zeziphene zemveliso ezibangelwa kukungcoliswa komhlwa kweziseko zesinyithi eziphosiweyo zibangela i-15% ukuya kwi-20% yokusilela kwemveliso kwiindawo zokusebenzela ezingenathuli.
Isisombululo segranite se-ZHHIMG sijongane ngokusisiseko nemingcipheko yongcoliseko lweziseko zesinyithi. Igranite yenziwe kakhulu ziiminerali ezifana ne-quartz kunye ne-feldspar. Ineempawu zeekhemikhali ezizinzileyo kakhulu, enoluhlu lokunyamezela i-pH oluyi-1 ukuya kwi-14. Ayisebenzi kangako kwii-reagents zekhemikhali eziqhelekileyo ze-acidic okanye ze-alkaline kwaye ayifakwanga i-oxidation kunye ne-oxygen okanye ukufuma emoyeni. Ke ngoko, akukho ngxaki yokugqwala. Okwangoku, isakhiwo sayo esixineneyo (i-porosity < 0.1%) senza umphezulu wayo ube mthe tyaba kwaye uthambe, kwaye akulula ukufunxa uthuli kunye nezinto ezingcolisayo. Nokuba isetyenziswa ixesha elide kwindawo yokusebenzela engenaluthuli eneemfuno eziphezulu zococeko, isenokugcina imeko yayo icocekile, iphephe ngempumelelo iziphumo ezimbi kwimveliso ezibangelwa kungcoliseko olusisiseko.
Okubaluleke ngakumbi kukuba isisombululo segranite se-ZHHIMG siphumelele isiqinisekiso sendalo se-ISO 14644-1 Class 5 cleanroom. Esi siqinisekiso sineemfuno ezisemgangathweni ezingqongqo zokuxinana kwamasuntswana axhonyiweyo emoyeni. Ngexesha leenyanga ezintathu ezilandelelanayo zovavanyo oluqatha, isiseko segranite se-ZHHIMG sihlala sigcina izinga lokukhululwa kwamasuntswana aphantsi kakhulu, siqinisekisa ukuba asizukubangela ungcoliseko kwindawo yokusebenzela engenathuli. Ukongeza, iqonga legranite likwanomlinganiselo ophantsi kakhulu wokwanda kobushushu kunye nokumelana okuhle kokungcangcazela. Ngelixa kuqinisekiswa ukucoceka kwendawo yokusebenzela engenathuli, inokubonelela ngenkxaso ezinzileyo yezixhobo ezichanekileyo, iphucula ukuchaneka kokusebenza kunye nokuthembeka kwezixhobo.
Emva kokuba ishishini elidumileyo lokuvelisa i-semiconductor lithathe isisombululo se-granite se-ZHHIMG ukuze sithathe indawo yesiseko sesinyithi esityhidiweyo, izinga leziphene zeemveliso zalo ezibangelwe lungcoliseko lehle kakhulu ukusuka kwi-8% ukuya kwi-1.5%, ukusebenza kakuhle kwemveliso kwanda ngama-25%, kwaye iindleko zonyaka ezisindisiweyo ngenxa yokulahlwa kwemveliso zidlule kwi-10 yezigidi zeeyuan. Le mpumelelo imangalisayo iqinisekisa ngokupheleleyo ixabiso elibalaseleyo lesisombululo se-granite se-ZHHIMG ekusombululeni imiba yongcoliseko kwiindawo zokusebenzela ezingenathuli.
Ngokuphuculwa okuqhubekayo kokuchaneka kwemveliso kunye neemfuno zomgangatho kumashishini ahlukeneyo, ukubaluleka kweendawo zokusebenzela ezingenathuli kuya kusanda. Izisombululo zegranite ze-ZHHIMG, ezineempawu zazo ezikhusela umhlwa, ezicocekileyo nezizinzileyo, kunye nenkxaso yesatifikethi enegunya, zibonelela ngeendlela ezisisiseko ezithembekileyo kumashishini, zinceda ishishini ukuba lihambe liye ekuveliseni ngokuchanekileyo okuphezulu kunye nomgangatho ophezulu.
