Ezweni elincane kakhulu lokukhiqizwa kwe-semiconductor, ukunemba kungumthetho ophakeme. Njengoba ubuchwepheshe benqubo ye-chip buqhubekela phambili enkathini yama-nanometer amabili, ngisho nokuphambuka okuncane kakhulu kokulinganisa kungaholela ekususweni kwamaqoqo onke ama-wafer, okubangela ukulahlekelwa okukhulu kwezomnotho. Ngokuphikisana nalokhu, "ama-gauge" asebenza njengezinkomba ze-metrological adlala indima ebalulekile. Ngenkathi ama-gauge ensimbi yendabuko esetshenziswa kabanzi, kancane kancane embula ukulinganiselwa kwawo lapho ebhekene nezidingo eziqinile kakhulu zemboni ye-semiconductor zokuhlanzeka, ukumelana nokugqwala, kanye nokuqina. Ama-gauge e-ceramic, anezakhiwo zawo zomzimba nezamakhemikhali ezihlukile, aba "abaqaphi abangabonakali" ababalulekile ku-metrology ye-semiconductor, enikeza ikhambi eliguqukayo lokunciphisa amaphutha okulinganisa.
Ngale Kwensimbi: Izinzuzo Ezibonakalayo Zama-Ceramic Gauges
Indawo yokukhiqiza ye-semiconductor ibeka izidingo ezicishe zibe nzima ezintweni zokulinganisa. Amabhulokhi ensimbi yendabuko, yize enobulukhuni obanele, athambekele ekugqwaleni lapho evezwa ezindaweni zokusebenzela isikhathi eside futhi avame ukuheha izinhlayiya zamagnetic—ingozi ebulalayo enkambisweni yokwenziwa kwe-wafer ebucayi kakhulu. Ngokuphambene nalokho, ama-ceramic gauge anembile—ikakhulukazi lawo enziwe nge-zirconia ehlanzekile kakhulu ne-alumina—abonisa izinzuzo ezinkulu.
Okokuqala, izinto zobumba zinesici semvelo "sokugqwala okungenawo umhlwa". Emakamelweni okuhlanza noma emalabhorethri okuhlola izinto ze-semiconductor, ukushintshashintsha komswakama akunakugwenywa. Amageji ensimbi adinga ukugcotshwa njalo ukuze kuvinjelwe ukugqwala, futhi ukuba khona kwefilimu kawoyela kushintsha ngqo ubukhulu begeji, okuletha amaphutha okulinganisa. Amageji e-ceramic aqeda ngokuphelele le ngozi, agcina izimo zobuso ezizinzile ngaphandle kwesidingo sokuvikelwa kawoyela. Okwesibili, amageji e-ceramic awasebenzi kuma-magnetic. Ekuhlolweni okubandakanya izingxenye ze-elekthronikhi ezibucayi, ukukhanga kwama-magnetic kungabamba imfucumfucu yensimbi emincane, engagcini nje ngokuklwebha ubuso bokulinganisa begeji kodwa futhi engcolisa ubuso be-wafer. Amageji e-ceramic avimbela ngokuphelele ukuphazamiseka ekukhangeni kwama-magnetic, eqinisekisa ubumsulwa bokuziphatha kokuthintana.
Okubaluleke kakhulu, kukhona ukumelana nokuguguleka. Izifundo zibonisa ukuthi ukumelana nokuguguleka kwezindawo zokusebenza ze-ceramic kungaphezu kokuphindwe kayishumi kunokwensimbi. Ngesikhathi sokuhlolwa kwemvamisa ephezulu nokuqinisekiswa usuku nosuku, ama-gauge e-ceramic abonisa ukuzulazula okuncane kakhulu, okusho ukwanda okukhulu kwemijikelezo yokulinganisa. Emigqeni yokukhiqiza ye-semiconductor ephishekela ukusebenza kahle okuphezulu, lokhu akusho nje kuphela ukuthembeka okuphezulu kokulinganisa kodwa futhi nezindleko zokusebenzisa zesikhathi eside eziphansi.
Ukuzinza Kokushisa: I-Anchor Emelene Nokushintshashintsha Kwezinga Lokushisa Elizungezile
Ku-metrology ye-semiconductor, izinga lokushisa lingenye yezinguquko ezinkulu ezithinta ukunemba kokulinganisa. Ngisho nokushintshashintsha okuncane kokushisa okuzungezile kungabangela ukwanda kokushisa kanye nokufinyela kwezinto zensimbi, okudala amaphutha okulinganisa angenakubalwa. Izinto ze-ceramic, ikakhulukazi i-aluminium ceramics ehlanzekile kakhulu, zine-coefficient ephansi kakhulu yokwanda kokushisa.
Lokhu kuzinza kokushisa okuphezulu kuvumela ama-ceramic gauge ukuthi alondoloze ukuhambisana okuphezulu kobukhulu bokubhekisela ngisho nalapho amazinga okushisa ashintsha—isibonelo, ngesikhathi sokushintsha kokushintsha noma ngenxa yokushintsha kokushisa kwendawo ekukhiqizweni. Lapho ama-steel gauge edlula ekuguqukeni kwezinga le-micron ngenxa yokufudumala kwesandla noma ukushintsha kokushisa kwegumbi, ama-ceramic gauge ahlala eqinile. Lesi sici sibaluleke kakhulu ezinqubweni zokuhlola ze-semiconductor ezidinga ukuqinisekiswa kwensimbi yesikhathi eside, ukulinganiswa kokuqhathanisa, kanye nokubekwa kwe-fixture. Kuqinisekisa ukuthi ireferensi yokulinganisa ihlala ingaguquguquki kungakhathaliseki ukuthi ilebhu ye-metrology elawulwa ukushisa noma phansi kwesitolo ngokushintshashintsha okukhulu, ngaleyo ndlela kunqanyulwe ukudluliselwa kwamaphutha abangelwa ukushintshashintsha kokushisa emthonjeni.
Ukuhlanzeka Nokumelana Nokugqwala: Ukuzivumelanisa Nezimo Zenqubo Ephakeme
Ukukhiqizwa kwe-semiconductor kuhilela ukusetshenziswa kakhulu kwamagesi amakhemikhali kanye nezinqubo ze-plasma, okuletha izinselele ezinkulu ekuzinzeni kwamakhemikhali kwama-gauge. Ezinqubweni ezifana nokusika kanye nokufakwa kwefilimu encane, ama-gauge ajwayelekile ensimbi noma epulasitiki aguguleka kalula ngamagesi agqwalisayo, okudala ukungcola kwezinhlayiya. Izinto zobumba ezihlanzekile kakhulu (njenge-alumina noma i-silicon nitride ehlanzekile ngaphezu kuka-99.6%) zibonisa ukumelana nokugqwala kwamakhemikhali, okukwazi ukumelana namagesi asekelwe ku-halogen kanye nezindawo ezine-acidic/alkaline.
Ngaphezu kwalokho, imboni ye-semiconductor isebenzisa ukulawula okukhulu ukungcola kwezinhlayiya. Amageyiji e-ceramic, anezindawo eziqondile - ezigayiwe kuya ebulukhunini obuphezulu kanye nokushelela, awathambekeli kakhulu ekuchithekeni kwezinhlayiya. Ngesikhathi sokudluliselwa nokuhlolwa kwe-wafer, ukusebenzisa izinto zobumba, izinkomishi zokumunca, noma ukuthola izikhonkwane kuvimbela ngempumelelo ukukhiqizwa kothuli ekungqubuzaneni kwensimbi. Lesi sici "esinobungani negumbi lokuhlanza" senza amageyiji e-ceramic hhayi nje ithuluzi lokulinganisa kodwa futhi abe ngumqaphi ogcina amazinga emvelo egumbi lokuhlanza. Ikakhulukazi emishinini eyinhloko efana nemishini ye-lithography kanye nezifakeli ze-ion, ukusetshenziswa kwezingxenye ze-ceramic kuqinisekisa ukuthi igumbi lenqubo lihlala lingenakho ukungcola kwe-ion yensimbi, ngaleyo ndlela kuvikeleke ukukhiqizwa kwe-chip.
Ukukhiqizwa Nokuqiniswa Okunembile: Ukuphishekela Ubuhle Kusukela Kokubalulekile Kuya Komkhiqizo Oqediwe
Ukuguqula izinzuzo zezinto zobumba zibe ukunemba kwangempela kokulinganisa akuhlukaniseki nezinqubo zokukhiqiza ngokunemba. Ukukhiqizwa kwama-semiconductor-grade ceramic gauges kuyiphrojekthi ehlelekile, edinga ukulawulwa okuqinile kuzo zonke izinyathelo kusukela ekulungisweni kwempuphu kanye nokucindezela kwe-isostatic kuya ekushiseni okushisa okuphezulu. Isibonelo, ukuqinisekisa ukuvumelana kobukhulu, ijika lokushisa lokushiseni kumele lilawulwe ngokunembile; noma yikuphi ukuphambuka kwemizuzu kungaholela ekucindezelekeni kwangaphakathi okungalingani, kamuva kuthinte ukuzinza kobukhulu besikhathi eside.
Esigabeni sokugcina, ukusetshenziswa kwezikhungo zomshini ezine-axis ezi-5 ezihambisana namathuluzi ambozwe ngedayimane kuvumela ukunemba komshini wamageyiji e-ceramic ukuthi kulawulwe ezingeni le-sub-micron. Lokhu mshini womshini onembile kakhulu awubonakali nje kuphela ekubekezeleleni ubukhulu kodwa futhi nasekulawuleni ubulukhuni bomphezulu. Izindawo zokulinganisa ezibushelelezi azigcini nje ngokunciphisa ukuguguleka kodwa futhi ziqinisekisa ukudluliselwa kwamandla okufanayo ngesikhathi sokulinganisa kokuxhumana. Njengamanje, imboni isungule izinhlelo ezijwayelekile eziqinile, njenge-ISO 3650, ezilawula amazinga okunemba (isb., K, 0, 00) wamageyiji e-ceramic, okuqinisekisa ukuthi ahlangabezana nezidingo eziphelele zemishini ye-semiconductor kusukela ekuhlanganisweni kwe-macro kuya ekuhlolweni kwe-micro.
Amathemba Okusetshenziswa: Ukwakha i-Ecosystem Yokulinganisa Okunembile Kakhulu
Njengoba ubuchwepheshe be-semiconductor buthuthuka bubheke kuma-node enqubo athuthukile, isidingo sokunemba kokulinganisa ngeke siphele. Izimo zokusetshenziswa kwama-gauge e-ceramic nazo ziyanda njalo, zishintsha kusukela kuma-gauge blocks endabuko kanye nama-ring gauge kuya ezingxenyeni zesakhiwo eziyinkimbinkimbi, njengezitsha zokusabalalisa igesi, ama-focus rings, kanye nama-electrostatic chucks. Ekuhlolweni kwamakhadi e-probe, ama-substrate e-silicon nitride ceramic, anokushisa okuphezulu kanye nokufakwa kukagesi, abe yizingxenye eziyinhloko ezithwala amashumi ezinkulungwane zama-probe okuhlolwa okuphezulu. Ezigabeni zomshini we-lithography, ama-silicon carbide ceramics, ngenxa yemvelo yawo elula kanye nokuqina okuphezulu, abe yizinto ezibalulekile zokufeza ukunyakaza okunembile kakhulu kwezinga le-nanometer.
Ngamafuphi, ukusetshenziswa kwama-ceramic gauge embonini ye-semiconductor akusikho nje ukufaka esikhundleni sezinto ezibonakalayo kodwa kuyinguquko ekuqondeni. Ngokususa izici zokuphazamiseka njengokugqwala, amandla kazibuthe, ukwanda kokushisa, kanye nokugqwala kwamakhemikhali, ama-ceramic gauge asungula ireferensi yokulinganisa ezinzile nethembekile yokukhiqizwa kwe-semiconductor. Esikhathini esizayo, ngentuthuko kwesayensi yezinto ezibonakalayo kanye nobuchwepheshe bokucubungula, ama-ceramic gauge azoqhubeka nokudlala indima enkulu ezweni elincane, esiza imboni ye-semiconductor ekuphishekeleni kwayo okungapheli kokunemba okuphelele.
