Kubalulekile ngoba i-chip yesimanje idlula kumakhulu ezinyathelo zenqubo, futhi ukuthuthukiswa okuncane engxenyeni yama-chips asebenzayo ngewafa ngayinye ihumusha ngokuqondile ukonga izindleko ezinkulu kanye nokunikezwa okwengeziwe.
I-Deep Dive
Isivuno ingxenyana yama-chips (efa) ku-wafer esebenza kahle. Izindwangu zilahlekelwa isivuno ngenxa yezinhlayiya ezingahleliwe, izinkinga zenqubo ehlelekile kanye nokukhukhuleka kancane kumishini. Ngenxa yokuthi i-wafer ingachitha amasonto endwangu, ukubamba izinsuku zenkinga sekwephuzile kungonakalisa inkatho eminingi. I-AI isiza ezindaweni ezintathu ezibalulekile. Okokuqala ukutholwa kokukhubazeka nokuhlukaniswa ngezigaba. Amathuluzi okuhlola ama-Optical kanye ne-electron-beam athola okudidayo kuma-wafer, futhi amamodeli okuhlukanisa okungalungile alebula ngohlobo. Ngokuhlukana, ukuhlolwa kukagesi kukhiqiza amamephu wewafer abonisa ukuthi yikuphi ukufa okuhlulekile. Iphethini yendawo iyinkomba: indandatho yonqenqema iphakamisa inkinga onqenqemeni lwewafer phakathi nenqubo efana nokubhala, kuyilapho ukuklwebha kuphakamisa ukubamba umonakalo. Idathasethi yomphakathi ye-WM-811K, ethathwe kumamephu we-wafer wangempela, isetshenziswa kabanzi ocwaningweni lokuhlukanisa lawa maphethini. Okwesibili i-virtual metrology. Ukukala yonke iwafa esinyathelweni ngasinye kuhamba kancane futhi kuyabiza, ngakho-ke isampula ye-fabs. I-Virtual metrology ibikezela imiphumela yokulinganisa evela kumathuluzi edatha yezinzwa asevele erekhodiwe, njengokucindezela, izinga lokushisa, ukugeleza kwegesi namandla e-RF, inikeze isilinganiso sayo yonke iwafa. Okwesithathu ukulawula inqubo. Ukutholwa kwamaphutha kanye nezinhlelo zokuhlukanisa ithuluzi lokubuka inzwa lilandelela ukuziphatha okungajwayelekile, nezilawuli ezigijimayo zilungisa amasethingi eresiphi phakathi kwenkatho ukuze zibambe imiphumela kukho okuqondiwe. Ukufunda ngomshini kungathuthuka kokubili ngokwenza ubudlelwano obungaqondile obugejiyo ukulawula inqubo yezibalo. Kunemibono eminingana eyiphutha evamile. Izindwangu azinawo amasethi edatha amakhulu anelebuli yalo lonke uhlobo lwesici: ukukhubazeka okungajwayelekile kungase kuvele izikhathi ezimbalwa kuphela, amakilasi awalingani kakhulu, futhi amalebula ancike konjiniyela abangochwepheshe. Amamodeli abuye aphelelwe yisikhathi lapho amathuluzi elungiswa noma kushintsha amaresiphi. Futhi isibikezelo sisodwa akwanele; onjiniyela badinga imbangela ebonakalayo ngaphambi kokuba baguqule inqubo. Lesi sihloko siphathelene nokukhiqiza, hhayi ukuklama kwesakhiwo se-chip.

Ikusasa le-AI ku-Semiconductor Fab Yield Optimization
Njengoba izici ze-chip zincipha futhi imiklamo ithuthela ezakhiweni ze-3D nokupakishwa okuthuthukile, inani lezinyathelo zenqubo kanye nedatha ngayinye ekhiqizwayo iyaqhubeka nokukhula, okwandisa isidingo sokuhlaziya okuzenzakalelayo. Izikhombisi-ndlela okungenzeka zibandakanya amamodeli ahlanganisa idatha kuzo zonke izinyathelo zokulandelela ukulahlekelwa kwesivuno emuva emthonjeni wayo, nezindlela ezingcono zokufunda ezibonelweni ezimbalwa ezinelebula. Ukutholwa kuzohlala kuqaphile: izindwangu zishintsha izinqubo kuphela ngobufakazi obuqinile, futhi ukulungiswa okuzenzakalelayo okungalungile kungalahla amawafa abizayo. Onjiniyela abangabantu kulindeleke ukuthi bahlale belawula izinqumo zembangela.
Ukuqaliswa Komhlaba Wangempela
Inethiwekhi ye-convolutional neural ihlukanisa amamephu we-wafer kusukela ekuhlolweni kukagesi ukuya emaphethini afana ne-edge-ring, isikhungo, ukuklwebha noma okungahleliwe, onjiniyela abakhomba isinyathelo senqubo okungenzeka sibe nephutha.
Imodeli ye-virtual metrology ibikezela ukushuba kwefilimu yawo wonke amawafa avela kumathuluzi wokulandela umkhondo wenzwa, ngakho-ke ingubo ikala ngokomzimba kuphela isampula ngenkathi isabamba ama-drift.
Ukuhlelwa kokukhubazeka okuzenzakalelayo kuhlunga izinkulungwane zezithombe zesibonakhulu se-electron zokuskena zokukhubazeka zibe izigaba ezinjengezinhlayiya, amabhuloho nokuwa kwephethini, ukusika isikhathi sokubuyekeza mathupha.
Isilawuli sokugijima silungisa isikhathi se-etch sendawo elandelayo ngokusekelwe emiphumeleni elinganisiwe nebikezelwe evela endaweni yangaphambilini, sinxephezela ukukhukhuleka kancane kancane kwegumbi.
