Yiziphi Izinkinga Ezivamile Zokusika I-Wafer Futhi Zingasiza Kanjani Ama-Laser Chillers?

Ama-wafer ayizinto eziyisisekelo ekukhiqizweni kwe-semiconductor, asebenza njengezinto ezisetshenziswayo zamasekethe ahlanganisiwe namanye amadivayisi e-microelectronic. Ngokuvamile enziwa nge-silicon e-monocrystalline, ama-wafer abushelelezi, ayisicaba, futhi ngokuvamile afinyelela ku-0.5 mm ubukhulu, anobubanzi obujwayelekile obungu-200 mm (8 inches) noma u-300 mm (12 inches). Inqubo yokukhiqiza iyinkimbinkimbi kakhulu, ehilela ukuhlanzwa kwe-silicon, ukunqunywa kwe-ingot, ukupholisha i-wafer, i-photolithography, ukuqopha, ukufakwa kwe-ion, i-electroplating, ukuhlolwa kwe-wafer, futhi ekugcineni, ukuhlukaniswa kwe-wafer. Ngenxa yezakhiwo zawo ezibonakalayo, ama-wafer adinga ukulawulwa okuqinile kokuhlanzeka, ukuthamba, kanye namazinga okukhubazeka, njengoba lokhu kuthinta ngqo ukusebenza kwe-chip.

Izinselele Ezivamile Zokusika I-Wafer

Ubuchwepheshe bokusika nge-laser busetshenziswa kabanzi ekucubungulweni kwe-wafer ngenxa yokunemba kwayo okuphezulu kanye nezinzuzo zokungathintani. Kodwa-ke, kungavela izinkinga eziningana zekhwalithi ngesikhathi sokusika:

Ama-Burrs kanye ne-Chipping: Lawa maphutha avame ukubangelwa ukungapholi kahle noma amathuluzi okusika agugile. Ukuthuthukisa uhlelo lokupholisa ngokuthuthukisa amandla okupholisa nokwandisa ukugeleza kwamanzi kungasiza ekunciphiseni ukufudumala okungalingani nokunciphisa umonakalo onqenqemeni.

Ukunemba Kokusika Okuncishisiwe: Kubangelwa ukubekeka kabi komshini, amatafula okusebenza angazinzile, noma amapharamitha okusika angalungile. Ukunemba kungabuyiselwa ngokuthuthukisa ukulinganiswa komshini kanye nokwenza ngcono izilungiselelo zamapharamitha.

Izindawo Ezisikiwe Ezingalingani: Ukuguguleka kwe-blade, izilungiselelo ezingafanele, noma ukungahambisani kahle kwe-spindle kungaholela ekungalungini komphezulu. Ukulungiswa njalo kanye nokulungiswa kabusha komshini kubalulekile ukuqinisekisa ukusika okubushelelezi.

Indima Yama-Laser Chillers Ekuhlukaniseni Ama-Wafer

Ama-laser chiller adlala indima ebalulekile ekugcineni ukusebenza kanye nokuqina kwezinhlelo ze-laser kanye ne-optical ezisetshenziswa ekuhlukaniseni i-wafer. Ngokunikeza ukulawula okunembile kokushisa, avimbela ukukhukhuleka kwe-laser wavelength okubangelwa ukushintshashintsha kokushisa, okubalulekile ekugcineni ukunemba kokusika. Ukupholisa okuphumelelayo kunciphisa nokucindezeleka kokushisa ngesikhathi sokusika, kunciphisa ingozi yokuphambuka kwe-lattice, ukuqhekeka, noma imifantu emincane engafaka ikhwalithi ye-wafer engcupheni.

Ngaphezu kwalokho, ama-laser chiller asebenzisa uhlelo lokupholisa amanzi oluvaliwe oluhlukanisa isekethe yokupholisa ekungcoleni kwangaphandle. Ngezinhlelo zokuqapha ezihlanganisiwe kanye nezinhlelo ze-alamu, zithuthukisa kakhulu ukuthembeka kwesikhathi eside kwemishini yokusika i-wafer.

Njengoba ikhwalithi yokusika nge-wafer ithinta ngqo ukukhiqizwa kwe-chip, ukufaka i-laser chiller ethembekile kusiza ukunciphisa amaphutha avamile nokugcina ukusebenza okulinganayo. Ukukhetha i-chiller efanele ngokusekelwe kumthwalo wokushisa wesistimu ye-laser kanye nendawo yokusebenza, kanye nokugcinwa njalo, kuyisihluthulelo sokuqinisekisa ukusebenza okuzinzile nokusebenza kahle.
