Emhlabeni onembile wokukhiqiza ama-semiconductor, ukuhlolwa okungabhubhisi kwama-wafers kuyisixhumanisi esibalulekile sokuqinisekisa ikhwalithi yama-chips. Isisekelo se-granite esibonakala singabalulekile empeleni "iqhawe elingaqashiwe" elinquma ukunemba kokutholwa. Kuyithinta kanjani emhlabeni imiphumela yokuhlolwa? Lesi sihloko sizokwenza ukuhlaziya okujulile kusuka kubukhulu obufana nezakhiwo zezinto ezibonakalayo kanye nomklamo wesakhiwo. .
1. Isisekelo Esizinzile: Izinzuzo zemvelo zegwadle zakha isisekelo esiqinile sokunemba
1. Ukusebenza okuhle kakhulu kwe-seismic
Ngesikhathi sokusebenza kwemishini yokuhlola eyisilutshwana engacekeli phansi, ukujikeleza kwemoto kanye nokunyakaza kwezakhi zemishini konke kuzokhiqiza ukudlidliza. Uma lokhu kudlidliza kungacindezelwa ngempumelelo, kuzophazamisa kakhulu ukunemba kokuhlola. Ingaphakathi le-granite lihlanganiswe eduze namakristalu amaminerali afana ne-quartz ne-feldspar. Isakhiwo sayo esiyingqayizivele siyinikeza amandla okumunca ukudlidliza kwemvelo, okukwazi ukumunca ngaphezu kwama-90% wamandla okudlidliza wemishini. Idatha yokulinganisa yangempela yomkhiqizi othile we-semiconductor ibonisa ukuthi ngemva kokusebenzisa isisekelo se-granite, i-amplitude yokudlidliza yemishini yokuthola yehlisiwe ukusuka ku-12μm ukuya ku-2μm, kugwema ngempumelelo ukuchezuka kwesignali yokuthola okubangelwa ukudlidliza. .
2. I-coefficient ephansi kakhulu yokunwetshwa kwe-thermal
Phakathi nenqubo yokuthola, izici ezifana nokushisisa kwemishini kanye noshintsho ekushiseni kwemvelo konke kuzothinta ukuzinza kwesisekelo somshini. Izinto ezivamile zanda kakhulu uma kushisa, kodwa i-coefficient yokwanda okushisayo kwegwadle ingu-1/5 kuphela wensimbi. Ngisho noma izinga lokushisa le-ambient liguquguquka ngo-10℃, ukuguqulwa kwalo kungase kunganakwa. Lokhu kwenza isisekelo se-granite sinikeze inkundla yereferensi ezinzile yempahla yokuhlola, iqinisekisa ukuthi indawo ehlobene phakathi kwe-probe yokuhlola ne-wafer ihlala inembile ngaso sonke isikhathi futhi igwema amaphutha okuhlola abangelwa ukuwohloka kokushisa. .
Okwesibili, ukuklama okunembayo: Ukwenza kahle kwesakhiwo kuthuthukisa ukuthembeka kokutholwa
Ukucubungula okuphezulu nokunemba isiqinisekiso
Isisekelo se-granite sekhwalithi ephezulu sicutshungulwa ubuchwepheshe obuthuthukisiwe be-CNC bokuxhumanisa ama-eksisi amahlanu, nobucaba obungu-±0.5μm/m, okunikeza ireferensi yokufaka eyi-ultra-flat yemishini yokuhlola. Ekuhlolweni kwe-wafer, ukuma kanye nezinga le-probe yokuhlola kubalulekile emiphumeleni yokuhlola. Isisekelo se-granite esinembe kakhulu singaqinisekisa ukuma okunembayo kwe-probe, kwenze idatha yokuhlola inembe kakhulu futhi ithembeke. .
2. Ukuzijwayeza kwesakhiwo ngendlela oyifisayo
Izisekelo zomshini we-granite zingenziwa ngokwezifiso zemishini yokuhlola eyisicwecwana ehlukile engacekeli phansi kanye nezidingo zenqubo. Isibonelo, ukuze kuhlangatshezwane nezidingo zemishini yokuhlola optical ukuze kukhanye ukukhanya, indawo engaphezulu yesisekelo somshini ingaphathwa ngokukhethekile; Ukuze kuhlangatshezwane nezidingo zokufakwa kwemishini yokuhlola ye-ultrasonic, isisekelo singenziwa ngaphambili ngezimbobo zokufaka ezinembile namathreyi ekhebula, okuvumela ukufakwa ngokushesha nokunembile kwemishini nokunciphisa ukuphambuka kokutholwa okubangelwa amaphutha okufaka. .
Iii. Ukuzinza kwesikhathi eside: Yehlisa ukulahleka okunembayo okubangelwa ukunakekelwa kwemishini
I-Granite inobunzima obuphezulu kanye nokumelana nokugqoka okuqinile, nobulukhuni be-Mohs obungu-6 kuya ku-7, okuphindwe kathathu ukumelana nokugqoka kwensimbi evamile. Ngesikhathi sokuhlolwa kwesikhathi eside, ingaphezulu lesisekelo somshini alijwayele ukugqokwa futhi lingahlala lisesimweni esihle sokunemba. Ngokuphambene, izisekelo ezenziwe ngezinye izinto zingase zibangele izinguquko kusithenjwa sokufakwa kwesisetshenziswa ngenxa yokuguga, lokho kuthinte ukunemba kokutholwa futhi kudinga ukulinganiswa nokugcinwa okuvamile. Impilo ende yesevisi nokuzinza okuphezulu kwesisekelo se-granite kunciphisa ngempumelelo imvamisa yokugcinwa kwemishini futhi kwehlise ingcuphe yokulahlekelwa ukunemba okungenzeka phakathi nenqubo yokulungisa. .
Kusukela ekumelaneni nokushaqeka, ukumelana nokushisa kuya ekwakhiweni okunembile, zonke izici zesisekelo se-granite zivikela ukunemba kokuhlolwa okungalimazi kwama-wafers. Esikhathini samanje sokukhiqiza i-semiconductor ephishekela ukunemba okuphelele, ukukhetha isisekelo se-granite sekhwalithi ephezulu kufana nokwengeza isendlalelo esiqinile somshwalense ekunembeni nasekuthembekeni kwemiphumela yokuhlolwa. .
