Nge-thermal coefficient of expansion (CTE) ye-7.2 × 10⁻⁶ /K (eqhelekileyo ye-aluminium), ukutshintshatshintsha kobushushu be-1°C kuphela kwi-substrate ye-100 mm kubangela utshintsho olukhulu lwe-720 nm—ngaphezulu kwe-14 amaxesha okunyamezelana kokulungelelanisa okufunekayo. Olu balo lulula lugxininisa isizathu sokuba ukukhetha izinto kungekuko ukucinga kwangaphambili kodwa yiparameter yoyilo olusisiseko.

Ingcaciso 1: Ukuhanjiswa kwe-Optical kunye nokusebenza kwe-Spectral

Kwi-laser interferometer ene-632.8 nm HeNe laser, ukuthamba komphezulu we-λ/4 (158 nm) kungenisa impazamo ye-wavefront ye-half-wave (ukuphambuka kabini komphezulu) kwisiganeko esiqhelekileyo. Oku kunokubangela iimpazamo zokulinganisa ezidlula i-100 nm—akwamkelekanga kwizicelo ze-precision metrology.
Uhlu ngokwesicelo:

Imingeni yoKwenziwa kweMveliso:

Ukufikelela kwi-λ/20 flatness kuzo zonke ii-substrates ezinkulu (200 mm+) kuzisa imingeni ebalulekileyo yokuvelisa. Ubudlelwane phakathi kobukhulu be-substrate kunye ne-flatness enokufezekiswa bulandela umthetho wesikwere: kumgangatho ofanayo wokucubungula, impazamo ye-flatness ilingana nesikwere sobubanzi. Ukuphinda kabini ubungakanani be-substrate ukusuka kwi-100 mm ukuya kwi-200 mm kunokunyusa umahluko we-flatness nge-4 factor.
Ityala leHlabathi lokwenyani:
Umenzi wezixhobo ze-lithography ekuqaleni wasebenzisa ii-substrates zeglasi ze-borosilicate ezine-λ/4 flatness kwizigaba zokulungelelanisa imaski. Xa betshintshela kwi-193 nm immersion lithography eneemfuno zokulungelelanisa ezingaphantsi kwe-30 nm, baphucula ukuya kwi-fused silica substrates ezine-λ/20 flatness. Isiphumo: ukuchaneka kokulungelelanisa kuphucukile ukusuka kwi-±80 nm ukuya kwi-±25 nm, kwaye amazinga eziphene ehla nge-67%.
Uzinzo ngokuhamba kwexesha:
Ukuthamba komphezulu akufuneki kufezekiswe kuphela ekuqaleni kodwa kugcinwe ubomi bonke becandelo. Ii-substrates zeglasi zibonisa uzinzo oluhle kakhulu lwexesha elide kunye nokuguquguquka kokuthamba okuqhelekileyo kungaphantsi kwe-λ/100 ngonyaka phantsi kweemeko zelebhu eziqhelekileyo. Ngokwahlukileyo koko, ii-substrates zesinyithi zinokubonisa ukuphumla koxinzelelo kunye nokuqhekeka, okubangela ukonakala kokuthamba ngokuhamba kweenyanga.

Ingcaciso 3: I-Coefficient of Thermal Expansion (CTE) kunye noZinzo loBushushu

Ipharamitha: I-CTE isusela kwi-close-zero (±0.05 × 10⁻⁶/K) kwizicelo ezichanekileyo kakhulu ukuya kwi-3.2 × 10⁻⁶/K kwizicelo ezifanisa i-silicon.
Kutheni Kubalulekile Kwiinkqubo Zokulungelelanisa:
Ukwandiswa kobushushu kumela umthombo omkhulu wokungazinzi kobukhulu kwiinkqubo zokulungelelanisa ukukhanya. Izinto ezingaphantsi komhlaba kufuneka zibonise utshintsho oluncinci lobukhulu phantsi kotshintsho lobushushu olufunyenweyo ngexesha lokusebenza, ukujikeleza kwendalo, okanye iinkqubo zokuvelisa.
Umngeni Wokwanda Kobushushu:
Kwi-substrate yokulungelelanisa eyi-200 mm:
I-CTE (×10⁻⁶/K) Utshintsho lweDimensional nge °C nganye Utshintsho kwimilinganiselo nge-5°C Utshintsho

  • Izicelo: Ulungelelwaniso oluqhelekileyo lwe-optical, iimfuno zokuchaneka okuphakathi
  • Inzuzo: Uthumelo olugqwesileyo lwe-optical, ixabiso eliphantsi
  • Umda: Ifuna ulawulo lobushushu olusebenzayo kwizicelo ezichanekileyo
Ukumelana noTshabalalo oluTshisayo:
Ngaphaya kobukhulu be-CTE, ukumelana nobushushu kubalulekile ekujikelezeni kobushushu ngokukhawuleza. Iiglasi ze-silica kunye ne-borosilicate ezixutyiweyo (kuquka i-Borofloat®33) zinokumelana nobushushu okugqwesileyo, zinyamezela umahluko wobushushu odlula i-100°C ngaphandle kokuqhekeka. Olu phawu lubalulekile kwiinkqubo zokulungelelanisa ezixhomekeke kutshintsho olukhawulezileyo lokusingqongileyo okanye ukufudumeza kwendawo okuvela kwiilaser ezinamandla aphezulu.
Isicelo seHlabathi lokwenyani:
Inkqubo yokulungelelanisa i-photonics yokudibanisa i-optical fiber isebenza kwindawo yokuvelisa iiyure ezingama-24/7 kunye notshintsho lobushushu olufikelela kwi-±5°C. Ukusebenzisa ii-substrates ze-aluminium (CTE = 23 × 10⁻⁶/K) kubangele utshintsho lobuchule bokudibanisa lwe-±15% ngenxa yotshintsho lobukhulu. Ukutshintshela kwi-AF 32® eco substrates (CTE = 3.2 × 10⁻⁶/K) kunciphisa utshintsho lobuchule bokudibanisa ukuya ngaphantsi kwe-±2%, nto leyo ephucula kakhulu isivuno semveliso.
Izinto ekufuneka uziqwalasele xa usebenzisa i-Gradient yobushushu:
Nokuba izinto ze-CTE ziphantsi, ii-gradients zobushushu kwi-substrate zinokubangela ukuphazamiseka kwendawo. Ukuze kube nokunyamezelana kwe-λ/20 flatness kwi-substrate engama-200 mm, ii-gradients zobushushu kufuneka zigcinwe ngaphantsi kwe-0.05°C/mm kwizixhobo ezine-CTE ≈ 3 × 10⁻⁶/K. Oku kufuna ukukhethwa kwezinto kunye noyilo olufanelekileyo lolawulo lobushushu.

Izinto zeglasi zibonelela ngobunzima obuthile obufana nobesinyithi kunye neenzuzo ezongezelelweyo: iipropati ezingezizo zemagnethi kunye nokungabikho kokulahleka kombane we-eddy.

Ukungqubana Kwangaphakathi Nokuxinana:
Ukungqubana kwangaphakathi (Q⁻¹) kumisela amandla ezinto zokukhupha amandla okungcangcazela. Iglasi idla ngokubonisa i-Q⁻¹ ≈ 10⁻⁴ ukuya kwi-10⁻⁵, nto leyo ebonelela ngokudambisa okungcono kwe-high-frequency kunezixhobo zekristale ezifana ne-aluminium (Q⁻¹ ≈ 10⁻³) kodwa ngaphantsi kunee-polymers. Olu phawu lokudambisa oluphakathi lunceda ekucinezeleni ukungcangcazela kwe-high-frequency ngaphandle kokuphazamisa ukuqina kwe-low-frequency.

Nangona kunjalo, uxinzelelo olubangelwa kukucubungula lunokubangela umboniso okwethutyana ochaphazela iinkqubo zokulungelelanisa ukukhanya okuphola. Kwizicelo zokulungelelanisa ngokuchanekileyo ezibandakanya imisebe ephola, uxinzelelo olushiyekileyo kufuneka lugcinwe lungaphantsi kwe-5 nm/cm (lulinganiswe kwi-632.8 nm).
Ukulungiswa kokunciphisa uxinzelelo:
Ukucoca ngokufanelekileyo kususa uxinzelelo lwangaphakathi:
  • Ubushushu obuqhelekileyo bokutsalela amanzi: 0.8 × Tg (ubushushu bokutshintsha kweglasi)
  • Ubude bokutsalwa kwe-Annealing: iiyure ezi-4-8 ubukhulu obuyi-25 mm (izikali ezinobukhulu obuphindwe kabini)
  • Izinga lokuphola: 1-5°C/iyure ukuya kwinqanaba lokuxinana
Ityala leHlabathi lokwenyani:
Inkqubo yokulungelelanisa ukuhlolwa kwe-semiconductor ifumene ukungalungelelani rhoqo nge-amplitude ye-0.5 μm kwi-150 Hz. Uphando lutyhile ukuba izibambi ze-aluminium substrate zazingcangcazela ngenxa yokusebenza kwezixhobo. Ukutshintsha i-aluminium ngeglasi ye-borofloat®33 (efana ne-CTE kwi-silicon kodwa ukuqina okuphezulu) kunciphise i-amplitude yokungcangcazela nge-70% kwaye kwasusa iimpazamo ze-amplitude rhoqo.

Umswakama kunye nokufunxwa kwamanzi:
Ukufunxwa kwamanzi kwiindawo zeglasi kunokuchaphazela ukusebenza kokukhanya kunye nokuzinza kokukhanya. Kumswakama oqhelekileyo we-50%, i-silica edibeneyo ifunxwa ngaphantsi kwe-1 monolayer yeemolekyuli zamanzi, nto leyo ebangela utshintsho oluncinci kumlinganiselo kunye nokulahleka kokudluliselwa kokukhanya. Nangona kunjalo, ungcoliseko lomphezulu kunye nokufuma kunokukhokelela ekwakhekeni kwamabala amanzi, oko kuthomalalise umgangatho womphezulu.
Ukuhambelana kwegesi kunye neVacuum:
Kwiinkqubo zokulungelelanisa ezisebenza kwi-vacuum (ezifana neenkqubo ze-optical ezisekelwe kwindawo okanye uvavanyo lwegumbi le-vacuum), ukukhupha igesi ngaphandle kwegesi yingxaki ebalulekileyo. Iglasi inezinga eliphantsi kakhulu lokukhupha igesi ngaphandle kwegesi:

  • I-Borosilicate: < 10⁻⁹ I-Torr·L/s·cm²
  • I-Aluminiyam: 10⁻⁸ – 10⁻⁷ I-Torr·L/s·cm²
Oku kwenza ii-substrates zeglasi zibe lolona khetho lukhethwayo kwiinkqubo zokulungelelanisa ezihambelana ne-vacuum.
Ukumelana nemisebe:
Kwizicelo ezibandakanya i-ionizing radiation (iinkqubo zesithuba, izixhobo zenyukliya, izixhobo ze-X-ray), ubumnyama obubangelwa yi-radiation bunokonakalisa uthumelo lwe-optical. Iiglasi eziqinileyo ze-radiation ziyafumaneka, kodwa ne-fused silica eqhelekileyo inokumelana okuhle kakhulu:

  • I-N-BK7: Ukulahleka kokudluliselwa kwe-transmission <1% kwi-400 nm emva kwe-1 krad
Uzinzo Lwexesha Elide:
Isiphumo esiqokelelweyo sezinto zeekhemikhali kunye nokusingqongileyo simisela uzinzo lwexesha elide. Kwizinto ezilungelelaniswe ngokuchanekileyo:
  • I-silica exutyiweyo: Uzinzo lobukhulu < 1 nm ngonyaka phantsi kweemeko zelebhu eziqhelekileyo

  • I-Aluminiyam: Ukushukuma kobukhulu be-10-100 nm ngonyaka ngenxa yokuphumla koxinzelelo kunye nokujikeleza kobushushu
Isicelo seHlabathi lokwenyani:
Inkampani yamayeza isebenzisa iinkqubo zokulungelelanisa i-optical ukuze ihlolwe ngokuzenzekelayo kwindawo yokucoca kunye nokucoca kwemihla ngemihla okusekelwe kwi-IPA. Ekuqaleni basebenzisa izixhobo zeplastiki ze-optical, bafumana ukonakala komphezulu okufuna ukutshintshwa rhoqo kwiinyanga ezi-6. Ukutshintshela kwi-borofloat®33 glass substrates kwandisa ubomi bezixhobo ukuya kwiminyaka engaphezu kwemi-5, kunciphisa iindleko zokulungisa nge-80% kwaye kususa ixesha lokungasebenzi elingalindelekanga ngenxa yokonakala kwe-optical.
