Kusukela ku-Semiconductor Fabs kuya ku-CMM: Kungani Izisekelo ze-Granite Ziba Ezibalulekile Ekukhiqizeni Okuphezulu Kobuchwepheshe

Uma uvule umshini wokulinganisa oqondile, ithuluzi lokubopha ucingo, noma uhlelo lokuhlola i-wafer emashumini ambalwa eminyaka edlule, cishe uzothola isisekelo sensimbi ecijile noma sensimbi ehlanganisiwe. Vula uhlobo olufanayo lwemishini namuhla, futhi kungenzeka ukuthi isisekelo sesakhiwo siyi-granite. Lokho kushintsha kwakungeyona into yokuhlobisa — kwalandela ngqo kulokho imishini yesimanje yokunemba ekudingayo kusukela esisekelweni sayo.

Izinkinga Zezisekelo Zensimbi Ezibhekene Nazo

Insimbi ephothiwe kanye nensimbi kuqinile, kodwa akuzona ezingenandaba nendawo ezikuyo. Izisekelo zensimbi ziyanda futhi zinciphe ngokulinganiswa ngokushisa, zigcina ukucindezeleka kwangaphakathi okusele okuvela ekuphothiweni noma ekushiseni okungakhululeka kancane eminyakeni edlule (kubangele ukugoba kancane kancane), futhi kudlulise ukudlidliza kahle kakhulu — akukho nokukodwa okuhle uma imishini ehleli phezu kwaleso sisekelo izama ukubamba ukuma kwezinga le-micron noma le-nanometer.

I-granite, ngokuphambene, izinzile ngokwesilinganiso uma isimbiwe, inomthamo ophansi wokwanda kokushisa, ayinayo ingcindezi yangaphakathi yokukhipha ukuze ikhululeke ngokuhamba kwesikhathi, futhi inezakhiwo zemvelo zokudlidliza ngenxa yesakhiwo sayo sekristalu. Emishinini lapho ukuzulazula kwesimo kuhumushela ngqo ephutheni lokulinganisa noma umphumela onephutha, lezo zakhiwo zibaluleke kakhulu kunamandla aluhlaza.

Lapho Izisekelo Zegranite Zivamile Manje

Uhlu lwezigaba zemishini ezisetshenziswayoizisekelo ze-graniteikhule kakhulu:

• Inqubo ye-semiconductor kanye nemishini yokuhlola, lapho ukubeka isiteji ezingeni le-nanometer kuyinto ejwayelekile
• Imishini yokulinganisa edidiyelwe (ama-CMM) kanye nezinhlelo zokulinganisa ze-optical/video, lapho ukuthamba kwesisekelo kunciphisa khona ngqo ukunemba kokulinganisa okufinyelelekayo
• Imishini yokubhoboza i-PCB kanye nemishini yokwakha, edinga ukubekwa njalo phakathi kwezinkulungwane zemijikelezo ephindaphindwayo
• Izinhlelo ze-laser ze-Femtosecond kanye ne-picosecond, lapho ukuzinza kwendlela ye-beam kuncike ekutheni isisekelo asishintshi ngaphansi komthwalo wokushisa
• Izigaba ze-Linear motor kanye namatafula e-XY asetshenziswa emigqeni yokuhlanganisa nokuhlola ezenzakalelayo
• Izinhlelo zokuhlola ze-CT neze-X-ray zezimboni, lapho ukulungiswa kwezithombe kuncike ekuzinzeni kwemishini ngesikhathi semijikelezo yokuskena
• Imishini yokuhlola izingxenye zebhethri kanye namandla amasha, uhlelo lokusebenza olukhula ngokushesha njengoba ukukhiqizwa kwe-EV kanye nebhethri kukhuphuka

Amathuluzi Okulinganisa I-Granite Njengesigaba Esihlukile

Ngale kwezisekelo zesakhiwo, i-granite iphinde ilawule amathuluzi okulinganisa ngokunemba — amapuleti obuso, ama-straightedges, izikwele, ama-V-blocks, kanye nama-parallels — asetshenziselwa ukulinganisa nokuqinisekisa eminye imishini. Ipuleti lobuso le-granite elisetshenziswa njengereferensi ye-metrology ngokuvamile lidinga ukubekezelelana okuqinile kokusicaba kunesisekelo se-granite esisetshenziswa ngokwesakhiwo, njengoba ipuleti ngokwalo liba yindinganiso yokunemba okuhlolwa ngayo ezinye izingxenye.

Lokhu Kusho Ukuthi Kubathengi Bemishini

Ezinkampanini ezichaza imishini emisha yokunemba noma ezishintsha izinhlelo ezisekelwe ensimbini ezindala, umphumela osebenzayo ukuthi isisekelo se-granite asiseyona intuthuko ephezulu - ezigabeni eziningi zezicelo, sesisondele ekulindelweni okuyisisekelo. Umehluko osele phakathi kwabaphakeli awukho mayelana nokukhetha izinto ezibonakalayo kodwa umayelana nobukhulu bokukhiqiza (ingabe umhlinzeki angakwazi yini ukufaka imishini yezingxenye ezinkulu zengxenye eyodwa ngaphandle kwamalunga angafuneki), kanye nokulawulwa kwekhwalithi (ingabe izimangalo zokuthamba nokuzinza zingasekelwa idatha yokulinganisa elandelekayo). Abakhiqizi abasebenzisa imigqa yokucubungula i-granite enamathani aphezulu kanye nemishini yokugaya enefomethi enkulu - abakwaziyo ukuphatha izingxenye eyodwa ebangeni lamathani angamashumi namamitha amaningana ubude - ngokuvamile basesimweni esingcono sokuhlinzeka ngohlobo lwezisekelo ze-granite ezinkulu, ezingenamalungu ezidingwa yimishini ye-semiconductor ephezulu kanye neyokuhlola edinga kakhulu.
