Emkhakheni wezinhlelo zokukhanya ezinembile kakhulu—kusukela kumishini ye-lithography kuya kuma-interferometer e-laser—ukunemba kokuqondanisa kunquma ukusebenza kwesistimu. Ukukhethwa kwezinto ezingaphansi komhlaba zamapulatifomu okuqondanisa okukhanya akusikho nje ukukhetha ukutholakala kodwa isinqumo sobunjiniyela esibalulekile esithinta ukunemba kokulinganisa, ukuzinza kokushisa, kanye nokuthembeka kwesikhathi eside. Lokhu kuhlaziywa kuhlola imininingwane emihlanu ebalulekile eyenza izinhlaka zokukhanya zeglasi ezinembile zibe yisinqumo esikhethwayo sezinhlelo zokuqondanisa okukhanya, ezisekelwa idatha yobuningi kanye nemikhuba emihle yemboni.
Isingeniso: Indima Ebalulekile Yezinto Ezingaphansi Kwe-Substrate Ekuqondisweni Kokukhanya
Izinhlelo zokuqondanisa ukukhanya zidinga izinto ezigcina ukuzinza okumangalisayo ngenkathi zihlinzeka ngezakhiwo zokubona eziphakeme. Kungakhathaliseki ukuthi zivumelanisa izingxenye ze-photonic ezindaweni zokukhiqiza ezenzakalelayo noma zigcina izindawo zokubhekisela ze-interferometric kuma-laboratories e-metrology, izinto ze-substrate kumele zibonise ukuziphatha okufanayo ngaphansi kwemithwalo yokushisa ehlukahlukene, ukucindezeleka komshini, kanye nezimo zemvelo.
Inselele Eyisisekelo:
Cabanga ngesimo esijwayelekile sokuqondanisa i-optical: ukuvumelanisa imicu ye-optical ohlelweni lokuhlanganisa i-photonics kudinga ukunemba kokubeka ngaphakathi kuka-±50 nm. Nge-thermal coefficient of expansion (CTE) engu-7.2 × 10⁻⁶ /K (ejwayelekile ye-aluminium), ukuguquguquka kwezinga lokushisa okungu-1°C kuphela ku-substrate engu-100 mm kubangela izinguquko zobukhulu obungu-720 nm—okungaphezu kwezikhathi ezingu-14 zokubekezelelana kokuqondanisa okudingekayo. Lokhu kubalwa okulula kugcizelela ukuthi kungani ukukhethwa kwezinto akuyona into ecatshangelwa kamuva kodwa kuyipharamitha yokuklama eyisisekelo.
Incazelo 1: Ukudluliselwa Kokukhanya kanye Nokusebenza Kwe-Spectral

Ukudluliselwa kwe-Optical kuthinta ngqo isilinganiso sesignali-kuya-kumsindo (i-SNR) sezinhlelo zokuvumelanisa. Ezinqubweni zokuvumelanisa ezisebenzayo, amamitha wamandla e-optical noma ama-photodetector alinganisa ukudluliselwa ohlelweni ukuze athuthukise ukuma kwengxenye. Ukudluliselwa okuphezulu kwe-substrate kwandisa ukunemba kokulinganisa futhi kunciphisa isikhathi sokuvumelanisa.
Umthelela Wobuningi:
Kumasistimu okuqondanisa okukhanya asebenzisa ukuqondanisa okudlula (lapho imisebe yokuqondanisa idlula khona ku-substrate), ukwanda ngakunye kokudlulisela okungu-1% kunganciphisa isikhathi somjikelezo wokuqondanisa ngo-3-5%. Ezindaweni zokukhiqiza ezenzakalelayo lapho ukudlula kulinganiswa ngezingxenye ngomzuzu, lokhu kuholela ekuzuzeni okukhulu kokukhiqiza.
Ukuqhathaniswa kwezinto ezibonakalayo:

Ubudlelwano phakathi kosayizi we-substrate kanye nobuthafa obungafinyeleleka bulandela umthetho wesikwele: ngekhwalithi efanayo yokucubungula, iphutha lobuthafa lilinganiswa cishe nesikwele sobubanzi. Ukuphinda kabili usayizi we-substrate kusuka ku-100 mm kuya ku-200 mm kungandisa ukwehluka kobuthafa ngesilinganiso esingu-4.
Icala Lomhlaba Wangempela:
Umkhiqizi wemishini ye-lithography ekuqaleni wasebenzisa ama-substrate engilazi e-borosilicate ane-λ/4 flatness ezigabeni zokuvumelanisa imaski. Lapho beshintshela ku-193 nm immersion lithography enezidingo zokuvumelanisa ezingaphansi kuka-30 nm, bathuthukela kuma-substrate e-silica ahlanganisiwe ane-λ/20 flatness. Umphumela: ukunemba kokuvumelanisa kuthuthukisiwe kusuka ku-±80 nm kuya ku-±25 nm, futhi amazinga okukhubazeka ehla ngo-67%.
Ukuzinza Ngokuhamba Kwesikhathi:
Ukuthamba komphezulu akumelwe kutholakale ekuqaleni kuphela kodwa kugcinwe isikhathi eside. Ama-substrate engilazi abonisa ukuzinza okuhle kakhulu kwesikhathi eside ngokushintshashintsha kokuthamba ngokuvamile kungaphansi kuka-λ/100 ngonyaka ngaphansi kwezimo ezijwayelekile zelebhu. Ngokuphambene nalokho, ama-substrate ensimbi angabonisa ukuphumula kokucindezeleka kanye nokukhukhuleka, okubangela ukuwohloka kokuthamba phakathi nezinyanga.

Ukumelana Nokushaqeka Okushisayo:
Ngale kobukhulu be-CTE, ukumelana nokushaqeka kokushisa kubalulekile ekushintsheni kokushisa okusheshayo. Izingilazi ze-silica ne-borosilicate ezihlanganisiwe (kufaka phakathi i-Borofloat®33) zibonisa ukumelana okuhle kakhulu nokushaqeka kokushisa, zibekezelela umehluko wokushisa odlula i-100°C ngaphandle kokuphuka. Lesi sici sibalulekile ezinhlelweni zokuqondanisa ezingaphansi kokushintsha okusheshayo kwemvelo noma ukushisa kwendawo okuvela kuma-laser anamandla amakhulu.
Isicelo Somhlaba Wangempela:
Uhlelo lokuqondanisa i-photonics lokuhlanganisa i-optical fiber lusebenza endaweni yokukhiqiza engu-24/7 enokushintshashintsha kwezinga lokushisa kufika ku-±5°C. Ukusebenzisa i-aluminium substrates (CTE = 23 × 10⁻⁶/K) kuholele ekushintsheni kokusebenza kahle kokuhlanganisa okungu-±15% ngenxa yezinguquko zobukhulu. Ukushintshela ku-AF 32® eco substrates (CTE = 3.2 × 10⁻⁶/K) kunciphise ukushintshashintsha kokusebenza kahle kokuhlanganisa kwaba ngaphansi kuka-±2%, okuthuthukisa kakhulu isivuno somkhiqizo.
Izinto Okucatshangwayo Nge-Gradient Yezinga Lokushisa:
Ngisho noma izinto ze-CTE eziphansi, ama-gradients okushisa kulo lonke i-substrate angabangela ukuphambuka kwendawo. Ukuze kube nokubekezelelana kwe-λ/20 flatness kulo lonke i-substrate engu-200 mm, ama-gradients okushisa kumele agcinwe ngaphansi kuka-0.05°C/mm ezintweni ezine-CTE ≈ 3 × 10⁻⁶/K. Lokhu kudinga kokubili ukukhethwa kwezinto kanye nomklamo wokuphathwa kokushisa ofanele.

Izinqubo Zokuqeda Ubuso
Ukugaya Nokupholisha:
Ukuqhubekela phambili kusukela ekugayeni okungaqinile kuya ekupholisheni kokugcina kunquma ikhwalithi yomphezulu kanye nokuba yisicaba:
- Ukugaya Okungafanele: Kususa izinto eziningi, kufinyelela ukubekezelelana kobukhulu ± 0.05 mm
- Ukugaya Okuncane: Kunciphisa ukujiya kobuso kube yi-Ra ≈ 0.1-0.5 μm
- Ukupholisha: Kufinyelela ukuqeda kokugcina kobuso be-Ra ≤ 0.5 nm
Ukupholisha Iphimbo vs. Ukupholisha Okulawulwa Yikhompyutha:
Ukupholisha kwephimbo lendabuko kungafinyelela ukuthamba okungu-λ/20 kuma-substrate amancane kuya kwaphakathi (kufika ku-150 mm). Kuma-substrate amakhulu noma lapho kudingeka khona ukugeleza okuphezulu, ukupholisha okulawulwa yikhompyutha (CCP) noma ukuqedela kwe-magnetorheological (MRF) kwenza:
- Ukuthamba okuhlala njalo kuzo zonke izisekelo ezingama-300-500 mm
- Isikhathi senqubo sincishisiwe ngo-40-60%
- Amandla okulungisa amaphutha emvamisa ephakathi nendawo
Ukucubungula Nokushisa:
Njengoba kushiwo ngaphambili, ukuncishiswa okufanele kubalulekile ekunciphiseni ukucindezeleka:
- Izinga lokushisa lokufaka: 0.8 × Tg (izinga lokushisa lokushintsha kwengilazi)
- Isikhathi sokucwilisa: amahora angu-4-8 (izikali ezinobukhulu obuyisikwele)
- Izinga lokupholisa: 1-5°C/ihora ngokusebenzisa indawo yokucindezeleka
Kumaglasi aphansi e-CTE njenge-ULE ne-Zerodur, ukujikeleza okwengeziwe kokushisa kungadingeka ukuze kufinyelelwe ukuzinza kobukhulu. "Inqubo yokuguga" ye-Zerodur ihilela ukujikeleza izinto phakathi kuka-0°C no-100°C amasonto amaningi ukuze kuqiniswe isigaba sekristalu.
