Marka laga hadlayo nidaamyada indhaha ee saxsan - laga bilaabo qalabka lithography ilaa qalabka laysarka - saxnaanta isku-xidhka ayaa go'aamisa waxqabadka nidaamka. Xulashada walxaha substrate-ka ee loogu talagalay goobaha isku-xidhka indhaha ma aha oo kaliya doorasho helitaan laakiin waa go'aan injineernimo oo muhiim ah oo saameeya saxnaanta cabbirka, xasilloonida kulaylka, iyo isku halaynta muddada-dheer. Falanqayntani waxay baareysaa shan qeexitaan oo muhiim ah oo ka dhigaya substrate-ka galaaska ee saxda ah doorashada la doorbidayo ee nidaamyada isku-xidhka indhaha, oo ay taageerayaan xogta tirada iyo dhaqamada ugu wanaagsan ee warshadaha.
Hordhac: Doorka Muhiimka ah ee Agabka Substrate-ka ee Iswaafajinta Indhaha
Nidaamyada isku-dubaridka indhaha waxay u baahan yihiin agab ilaaliya xasilloonida cabbirka ee aan caadiga ahayn iyagoo bixinaya sifooyin aragti oo heer sare ah. Hadday tahay in qaybaha photonic-ga lagu hagaajiyo jawiyada wax-soo-saarka ee otomaatiga ah ama in la ilaaliyo dusha sare ee tixraaca interferometric ee shaybaarrada metrology-ga, walxaha substrate-ka ah waa inay muujiyaan dhaqan joogto ah iyadoo la raacayo culeysyo kuleyl oo kala duwan, cadaadis farsamo, iyo xaalado deegaan.
Caqabadda Aasaasiga ah:
Ka fiirso xaalad caadi ah oo isku-habaynta indhaha ah: isku-hagaajinta fiilooyinka indhaha ee nidaamka isku-dubaridka photonics waxay u baahan tahay saxnaanta meelaynta gudaha ±50 nm. Iyada oo leh isku-xidhka kulaylka ee ballaarinta (CTE) ee 7.2 × 10⁻⁶ /K (sida caadiga ah ee aluminiumka), isbeddelka heerkulka oo ah 1°C oo keliya oo ku yaal substrate 100 mm ah wuxuu sababaa isbeddello cabbir ah oo ah 720 nm - in ka badan 14 jeer dulqaadka isku-habaynta ee loo baahan yahay. Xisaabintan fudud waxay hoosta ka xariiqaysaa sababta xulashada agabku aysan ahayn fikir dambe laakiin ay tahay halbeegga naqshadaynta aasaasiga ah.
Tilmaamaha 1aad: Gudbinta Indhaha iyo Waxqabadka Muuqaalka
Halbeegga: Gudbinta >92% inta u dhaxaysa dhererka hirarka ee la cayimay (badanaa 400-2500 nm) oo leh qallafsanaan dusha sare ah Ra ≤ 0.5 nm.
Sababta ay Muhiim ugu tahay Nidaamyada Isku-dubaridka:
Gudbinta indhaha si toos ah ayay u saamaysaa saamiga calaamadda-ilaa-qaylada (SNR) ee nidaamyada isku-xidhka. Hawlaha isku-xidhka firfircoon, mitirada awoodda indhaha ama sawir-qaadayaasha ayaa cabbira gudbinta iyada oo loo marayo nidaamka si loo wanaajiyo booska qaybaha. Gudbinta substrate-ka oo sareysa waxay kordhisaa saxnaanta cabbirka waxayna yareysaa waqtiga isku-xidhka.
Saamaynta Tirada:
Nidaamyada isku-xidhka indhaha ee adeegsanaya isku-xidhka gudbinta-dhexdeeda (halkaas oo ay fallaadhaha isku-xidhka ay dhex maraan substrate-ka), koror kasta oo 1% ah oo ku yimaada gudbinta waxay yareyn kartaa waqtiga wareegga isku-xidhka 3-5%. Deegaannada wax-soo-saarka ee otomaatiga ah halkaas oo wax-soo-saarka lagu cabbiro qaybo daqiiqaddii, tani waxay u tarjumeysaa faa'iidooyin wax-soo-saar oo muhiim ah.
Isbarbardhigga Agabka:
| Alaab | Gudbinta Muuqda (400-700 nm) | Gudbinta Ku Dhaw-IR (700-2500 nm) | Awoodda Qalafsanaanta Dusha Sare |
|---|---|---|---|
| N-BK7 | >95% | >95% | Ra ≤ 0.5 nm |
| Silica la isku daray | >95% | >95% | Ra ≤ 0.3 nm |
| Borofloat®33 | ~92% | ~90% | Ra ≤ 1.0 nm |
| AF 32® eco | ~93% | >93% | Ra < 1.0 nm RMS |
| Zeduror® | Lama arki karo (muuqaal ahaan ma muuqato) | Lama Helin | Ra ≤ 0.5 nm |
Tayada Dusha Sare iyo Kala-baxa:
Qallafsanaanta dusha sare waxay si toos ah ula xiriirtaa khasaaraha kala firdhisan. Sida laga soo xigtay aragtida kala firdhinta Rayleigh, khasaaraha kala firdhisan waxay la mid tahay awoodda lixaad ee qallafsanaanta dusha sare marka loo eego hirarka. Si loo helo iftiin isku-xidhan oo laysarka HeNe ah oo 632.8 nm ah, yaraynta qallafsanaanta dusha sare laga bilaabo Ra = 1.0 nm ilaa Ra = 0.5 nm waxay yareyn kartaa xoogga iftiinka kala firdhisan 64%, taasoo si weyn u hagaajinaysa saxnaanta isku-xidhka.
Codsiga Dhabta ah:
Nidaamyada isku-dubaridka photonics-ka heerka wafer-ka, isticmaalka substrates-ka silica ee la isku daray oo leh dhammaystirka dusha sare ee Ra ≤ 0.3 nm waxay suurtogal ka dhigaysaa saxnaanta isku-dubaridka inay ka fiican tahay 20 nm, taasoo lagama maarmaan u ah aaladaha silicon photonic ee leh dhexroorka goobta qaabka ka hooseeya 10 μm.
Tilmaamaha 2: Fidsanaanta Dusha sare iyo Xasiloonida Cabbirka
Halbeegga: Fidsanaan dusha sare ah ≤ λ/20 at 632.8 nm (qiyaastii 32 nm PV) oo leh isku midnimo dhumucdeed ±0.01 mm ama ka wanaagsan.
Sababta ay Muhiim ugu tahay Nidaamyada Isku-dubaridka:
Fidsanaanta dusha sare waa qeexidda ugu muhiimsan ee substrate-ka isku-xidhka, gaar ahaan nidaamyada indhaha ee milicsanaya iyo codsiyada interferometric. Kala leexashada fidsanaanta waxay keentaa khaladaad ku yimaada mowjadaha kuwaas oo si toos ah u saameeya saxnaanta isku-xidhka iyo saxnaanta cabbirka.
Shuruudaha Fiisigiska ee Fidsanaan:
Qalabka laysarka ee dhexgalaha ah oo leh laysarka HeNe ee 632.8 nm, fidsanaanta dusha sare ee λ/4 (158 nm) waxay soo bandhigaysaa qalad mowjad ah oo ah nus mowjad (laba jeer oo ka leexashada dusha sare) marka ay dhacdo caadi ah. Tani waxay sababi kartaa khaladaad cabbir oo ka badan 100 nm—aan la aqbali karin codsiyada saxda ah ee mitirka.
Kala soocidda Codsiga:
| Tilmaamaha Fidsanaan | Fasalka Codsiga | Kiisaska Isticmaalka Caadiga ah |
|---|---|---|
| ≥1λ | Heerka ganacsiga | Iftiimin guud, iswaafajin aan muhiim ahayn |
| λ/4 | Heerka shaqada | Laysarro awood yar oo dhexdhexaad ah, nidaamyada sawir-qaadista |
| ≤λ/10 | darajada saxda ah | Laysarka awoodda sare leh, nidaamyada mitirka |
| ≤λ/20 | Aad u saxsan | Interferometry, lithography, isu imaatinka photonics |
Caqabadaha Wax Soo Saarka:
Gaaritaanka fidsanaanta λ/20 ee substrate-ka waaweyn (200 mm+) waxay soo bandhigaysaa caqabado wax soo saar oo muhiim ah. Xiriirka ka dhexeeya cabbirka substrate-ka iyo fidsanaanta la gaari karo wuxuu raacayaa sharci laba jibbaaran: tayada farsamaynta isku mid ah, qaladka fidsanaanta wuxuu ku qiyaasan yahay labajibbaaranaha dhexroorka. Cabbirka substrate-ka oo labanlaabma laga bilaabo 100 mm ilaa 200 mm wuxuu kordhin karaa kala duwanaanshaha fidsanaanta qodob 4 ah.
Kiiska Dhabta ah:
Soo saaraha qalabka lithography ayaa markii hore isticmaalay walxo galaas ah oo borosilicate ah oo leh fidsanaan λ/4 marxaladaha isku-dubaridka maaskarada. Markii loo gudbayay lithography-ga 193 nm ee ku-darka oo leh shuruudaha isku-dubaridka oo ka hooseeya 30 nm, waxay u cusboonaysiiyeen substrate-ka silica ee isku dhafan oo leh fidsanaan λ/20. Natiijada: saxnaanta isku-dubaridka ayaa ka soo hagaagtay ±80 nm ilaa ±25 nm, heerarka cilladahana waxay hoos u dhaceen 67%.
Xasilloonida Waqti Ka Dib:
Fidsanaanta dusha sare waa in aan la gaarin oo keliya marka hore laakiin la ilaaliyaa inta uu le'eg yahay qaybta. Substrates-ka galaaska waxay muujiyaan xasillooni muddo dheer ah oo aad u fiican iyadoo kala duwanaanshaha fidsanaanta uu caadi ahaan ka yar yahay λ/100 sannadkii xaaladaha caadiga ah ee shaybaarka. Taas bedelkeeda, substrates-ka birta ah waxay muujin karaan nasasho walaac iyo gurguur, taasoo keenta burbur fidsanaan bilo gudahood.
Faahfaahinta 3: Isku-darka Ballaarinta Kulaylka (CTE) iyo Xasilloonida Kulaylka
Halbeegga: CTE wuxuu u dhexeeyaa eber u dhow (±0.05 × 10⁻⁶/K) codsiyada aadka u saxsan ilaa 3.2 × 10⁻⁶/K codsiyada isku-dhafka ah ee silikoon.
Sababta ay Muhiim ugu tahay Nidaamyada Isku-dubaridka:
Ballaarinta kulaylka waxay ka dhigan tahay isha ugu weyn ee xasillooni darrada cabbirka ee nidaamyada isku-xidhka indhaha. Alaabada hoose waa inay muujiyaan isbeddel cabbir yar marka loo eego kala duwanaanshaha heerkulka ee la kulmo inta lagu jiro hawlgalka, wareegga deegaanka, ama hababka wax soo saarka.
Caqabadda Ballaarinta Kulaylka:
Substrate-ka isku-xidhka 200 mm:
| CTE (×10⁻⁶/K) | Isbeddelka Cabbirka halkii °C | Isbeddelka Cabbirka Kala Duwanaanshaha 5°C kasta |
|---|---|---|
| 23 (Aluminium) | 4.6 μm | 23 μm |
| 7.2 (Birta) | 1.44 μm | 7.2 μm |
| 3.2 (AF 32® eco) | 0.64 μm | 3.2 μm |
| 0.05 (ULE®) | 0.01 μm | 0.05 μm |
| 0.007 (Zerodur®) | 0.0014 μm | 0.007 μm |
Fasallada Agabka ee CTE:
Muraayadaha Ballaarinta Aad u Hooseeya (ULE®, Zedurod®):
- CTE: 0 ± 0.05 × 10⁻⁶/K (ULE) ama 0 ± 0.007 × 10⁻⁶/K (Zerodur)
- Codsiyada: Interferometry sax ah oo aad u sarreeya, teleskoobyada hawada sare, muraayadaha tixraaca lithography
- Ganacsi: Kharash sare, gudbinta indhaha oo xaddidan oo ku jirta muuqaalka muuqda
- Tusaale: Muraayadda Hubble Space Telescope substrate waxay isticmaashaa galaaska ULE oo leh CTE < 0.01 × 10⁻⁶/K
Muraayadaha Silikoon-ku-habboon (AF 32® eco):
- CTE: 3.2 × 10⁻⁶/K (si dhow ayuu ugu habboon yahay siliconka 3.4 × 10⁻⁶/K)
- Codsiyada: Baakadaha MEMS, isdhexgalka silicon photonics, tijaabada semiconductor
- Faa'iido: Waxay yareysaa cadaadiska kulaylka ee isku-xidhka isku-xidhka
- Waxqabadka: Waxay awood u siineysaa isku dheelitir la'aanta CTE ee ka hooseysa 5% iyadoo la adeegsanayo substrate-ka silicon.
Muraayadda Indhaha ee Caadiga ah (N-BK7, Borofloat®33):
- CTE: 7.1-8.2 × 10⁻⁶/K
- Codsiyada: Isku-dubaridka guud ee indhaha, shuruudaha saxda ah ee dhexdhexaadka ah
- Faa'iidada: Gudbinta indhaha oo aad u fiican, kharash yar
- Xaddidaadda: Waxay u baahan tahay xakamaynta heerkulka firfircoon ee codsiyada saxnaanta sare leh
Iska caabinta Shoogga Kulaylka:
Marka laga reebo baaxadda CTE, iska caabbinta shoogga kulaylka ayaa muhiim u ah wareegga heerkulka degdegga ah. Muraayadaha silica iyo borosilicate ee la isku daray (oo ay ku jiraan Borofloat®33) waxay muujiyaan iska caabbin shoogga kulaylka oo aad u fiican, iyagoo u adkeysan kara kala duwanaanshaha heerkulka oo ka badan 100°C iyada oo aan jabin. Hantidani waxay lagama maarmaan u tahay nidaamyada isku-dubaridka ee ku xiran isbeddellada degdegga ah ee deegaanka ama kuleylinta maxalliga ah ee ka timaadda laysarka awoodda sare leh.
Codsiga Dhabta ah:
Nidaamka isku-xidhka photonics ee isku-xidhka fiber-ka indhaha wuxuu ka shaqeeyaa jawi wax-soo-saar 24/7 ah oo leh kala duwanaansho heerkul ah ilaa ±5°C. Isticmaalka substrate-ka aluminiumka ah (CTE = 23 × 10⁻⁶/K) wuxuu keenay kala duwanaansho hufnaanta isku-xidhka oo ah ±15% sababtoo ah isbeddellada cabbirka. U beddelashada substrate-ka AF 32® eco (CTE = 3.2 × 10⁻⁶/K) waxay yareysay kala duwanaanshaha hufnaanta isku-xidhka oo ka yar ±2%, taasoo si weyn u wanaajisay wax-soo-saarka badeecada.
Tixgelinta Heerkulka:
Xitaa iyadoo walxaha CTE ay hooseeyaan, heerarka heerkulka ee ku wareegsan substrate-ka waxay sababi karaan qallooc maxalli ah. Si loogu dulqaado fidsanaanta λ/20 ee substrate-ka 200 mm, heerarka heerkulka waa in lagu hayaa meel ka hooseysa 0.05°C/mm walxaha leh CTE ≈ 3 × 10⁻⁶/K. Tani waxay u baahan tahay labadaba xulashada agabka iyo naqshadeynta maaraynta kulaylka saxda ah.
Tilmaamaha 4: Sifooyinka Farsamada iyo Daminta Gariirka
Halbeegga: Modulus-ka Young 67-91 GPa, is-qabsiga gudaha Q⁻¹ > 10⁻⁴, iyo maqnaanshaha isku-xidhka cadaadiska gudaha.
Sababta ay Muhiim ugu tahay Nidaamyada Isku-dubaridka:
Xasiloonida farsamada waxay ka kooban tahay adkeysiga cabbirka ee culayska saaran, sifooyinka yareynta gariirka, iyo iska caabbinta birefringence-ka uu keeno cadaadiska - dhammaantoodna waa muhiim si loo ilaaliyo saxnaanta isku-xidhka jawiga firfircoon.
Modulus-ka Laablaaban iyo Adkaanta:
Modulus-ka dabacsan ee sare wuxuu u tarjumaa iska caabin weyn oo loo qabo leexashada marka culaysku saaran yahay. Si aad u hesho qaab-dhismeed dherer L ah oo si fudud loo taageeray, dhumucda t, iyo modulus-ka dabacsan E, leexashada marka culaysku saaran yahay oo leh L³/(Et³). Xiriirkan labajibbaaran ee la leh dhumucda iyo xiriirka tooska ah ee dhererka ayaa hoosta ka xariiqaya sababta adkaanta ay muhiim ugu tahay substrate-ka waaweyn.
| Alaab | Modulus-ka Young (GPa) | Adkayn Gaar ah (E/ρ, 10⁶ m) |
|---|---|---|
| Silica la isku daray | 72 | 32.6 |
| N-BK7 | 82 | 34.0 |
| AF 32® eco | 74.8 | 30.8 |
| Aluminium 6061 | 69 | 25.5 |
| Bir (440C) | 200 | 25.1 |
U fiirsasho: In kasta oo birtu ay leedahay adkaanta ugu sarreysa, haddana adkaanta gaarka ah (saamiga adkaanta iyo miisaanka) waxay la mid tahay aluminium. Agabka galaaska wuxuu bixiyaa adkaansho gaar ah oo la barbar dhigi karo biraha oo leh faa'iidooyin dheeraad ah: sifooyinka aan birlab ahayn iyo maqnaanshaha khasaaraha hadda jira.
Khilaafka Gudaha iyo Qoyaanka:
Is-xoqidda gudaha (Q⁻¹) waxay go'aamisaa awoodda walaxdu u leedahay inay kala firdhiso tamarta gariirka. Muraayadda ayaa caadi ahaan soo bandhigta Q⁻¹ ≈ 10⁻⁴ ilaa 10⁻⁵, taasoo bixisa qoyaan soo noqnoqosho sare oo ka wanaagsan walxaha kristalinta sida aluminium (Q⁻¹ ≈ 10⁻³) laakiin ka yar polymers-ka. Astaantan qoyaanka dhexdhexaadka ah waxay gacan ka geysataa xakamaynta gariirka soo noqnoqoshada sare iyada oo aan wax u dhimin adkaanta soo noqnoqoshada hoose.
Istaraatiijiyadda Go'doominta Gariirka:
Meelaha isku-xidhka indhaha, walxaha substrate-ka waa inay la shaqeeyaan nidaamyada go'doominta:
- Go'doomin Soo noqnoqosho Yar: Waxaa bixiya go'doomiyayaal neef-mareen ah oo leh soo noqnoqosho soo noqnoqosho ah 1-3 Hz
- Damping-Mid-Frequency: Waxaa xakameeyay isku-dhafka gudaha ee substrate-ka iyo naqshadaynta qaab-dhismeedka
- Shaandhaynta Soo noqnoqoshada Sare: Waxaa lagu gaaraa rarista tirada badan iyo is-waafajinta iska caabbinta
Xiriirka Walwalka:
Muraayaddu waa walax aan qaab lahayn sidaas darteedna waa inaysan muujin bir-bireed gudaha ah. Si kastaba ha ahaatee, cadaadiska uu keeno farsamayntu wuxuu sababi karaa bir-bireed ku meel gaar ah oo saameeya nidaamyada isku-dubaridka iftiinka ee kala fog. Si loo isticmaalo isku-dubaridka saxda ah ee ku lug leh alwaaxyada kala fog, cadaadiska haraaga ah waa in lagu hayaa meel ka hooseysa 5 nm/cm (oo lagu cabbiro 632.8 nm).
Habaynta Yaraynta Walbahaarka:
Nadiifinta saxda ah waxay meesha ka saartaa walbahaarka gudaha:
- Heerkulka caadiga ah ee qaboojinta: 0.8 × Tg (heerkulka kala-guurka galaaska)
- Muddada qaboojinta: 4-8 saacadood oo dhumucdiisu tahay 25 mm (miisaan leh dhumuc labajibbaaran)
- Heerka qaboojinta: 1-5°C/saacaddii iyada oo loo marayo barta cadaadiska
Kiiska Dhabta ah:
Nidaamka kormeerka isku-xidhka semiconductor-ka ayaa la kulmay is-waafajin xilliyeed oo leh 0.5 μm oo ah 150 Hz. Baaritaanku wuxuu muujiyay in hayayaasha aluminium-ka ay gariirayeen sababtoo ah shaqada qalabka. Beddelka aluminium-ka galaas borofloat®33 ah (oo la mid ah CTE iyo silicon laakiin adkaansho gaar ah oo sarreeya) wuxuu yareeyay baaxadda gariirka 70% wuxuuna meesha ka saaray khaladaadka is-waafajinta xilliyeed.
Awoodda Rarka iyo Kala-leexashada:
Meelaha isku-xidhka ee taageeraya muraayadaha indhaha ee culus, waa in la xisaabiyaa leexashada culayska saaran. Substrate silica ah oo dhexroorkiisu yahay 300 mm, oo dhumucdiisu tahay 25 mm, ayaa ka leexisa wax ka yar 0.2 μm marka la eego culayska 10 kg ee dhexe lagu dabaqo - oo aan loo baahnayn inta badan codsiyada isku-xidhka indhaha ee u baahan saxnaanta meelaynta ee heerka 10-100 nm.
Tilmaamaha 5: Xasiloonida Kiimikada iyo Iska caabinta Deegaanka
Halbeegga: Iska caabbinta Haydarooliga Fasalka 1aad (sida ISO 719 u qabo), iska caabbinta aashitada Fasalka A3, iyo iska caabbinta cimilada oo ka badan 10 sano iyada oo aan la burburin.
Sababta ay Muhiim ugu tahay Nidaamyada Isku-dubaridka:
Xasiloonida kiimikada waxay hubisaa xasilloonida cabbirka muddada dheer iyo waxqabadka indhaha ee deegaanno kala duwan - laga bilaabo qolalka nadiifka ah ee leh wakiilada nadiifinta ee gardarrada ah ilaa goobaha warshadaha oo leh soo-gaadhista dareerayaasha, qoyaanka, iyo wareegga heerkulka.
Kala-soocidda Iska caabbinta Kiimikada:
Walxaha galaaska waxaa lagu kala saaraa iska caabbinta deegaanno kiimikooyin kala duwan:
| Nooca Iska caabinta | Habka Tijaabada | Kala-soocidda | Xadka |
|---|---|---|---|
| Hawo-mareenka | ISO 719 | Fasalka 1aad | <10 μg Na₂O u dhiganta garaamkii |
| Asiidh | ISO 1776 | Fasalka A1-A4 | Miisaanka oo luma ka dib soo-gaadhista aashitada |
| Alkali | ISO 695 | Fasalka 1-2 | Miisaanka oo yaraada ka dib soo-gaadhista alkali |
| Cimilada | Soo-gaadhista dibadda | Aad u fiican | Ma jiro hoos u dhac la qiyaasi karo 10 sano kadib |
Iswaafajinta Nadiifinta:
Nidaamyada isku-hagaajinta indhaha waxay u baahan yihiin nadiifin joogto ah si loo ilaaliyo waxqabadka. Walxaha nadiifinta ee caadiga ah waxaa ka mid ah:
- Khamriga isopropyl (IPA)
- Asetone
- Biyaha la dhalaaliyay
- Xalalka nadiifinta indhaha ee gaarka ah
Muraayadaha silica iyo borosilicate ee isku dhafan waxay muujiyaan iska caabin aad u fiican dhammaan walxaha nadiifinta ee caadiga ah. Si kastaba ha ahaatee, qaar ka mid ah muraayadaha indhaha (gaar ahaan muraayadaha dhagaxa leh ee leh sunta rasaasta badan) waxaa weerari kara dareereyaal gaar ah, taasoo xaddidaysa fursadaha nadiifinta.
Qoyaanka iyo nuugista biyaha:
Nuugista biyaha ee dusha sare ee galaaska waxay saameyn kartaa waxqabadka indhaha iyo xasilloonida cabbirka labadaba. Qoyaanka 50% ee qaraabada ah, silica isku dhafan waxay nuugtaa wax ka yar 1 lakab oo ka mid ah molecules-ka biyaha, taasoo keenta isbeddel cabbir oo aan la saadaalin karin iyo luminta gudbinta indhaha. Si kastaba ha ahaatee, wasakhowga dusha sare oo ay weheliso qoyaanku wuxuu horseedi karaa sameynta dhibco biyo ah, taasoo hoos u dhigaysa tayada dusha sare.
Iswaafajinta Gaaska iyo Faakiyuumka:
Nidaamyada isku-dubaridka ee ka shaqeeya faakuumka (sida nidaamyada indhaha ee ku salaysan booska ama tijaabinta qolka faakuumka), qiiqa ka baxa waa walaac muhiim ah. Galaasku wuxuu muujinayaa heerarka qiiqa ka baxa oo aad u hooseeya:
- Silica la isku daray: < 10⁻¹⁰ Torr·L/s·cm²
- Borosilicate: < 10⁻⁹ Torr·L/s·cm²
- Aluminium: 10⁻⁸ – 10⁻⁷ Torr·L/s·cm²
Tani waxay ka dhigaysaa substrates galaas ah doorashada la door bidayo ee nidaamyada isku-habaynta ee ku habboon faakuumka.
Iska caabbinta Shucaaca:
Codsiyada ku lug leh shucaaca ionizing (nidaamyada hawada sare, xarumaha nukliyeerka, qalabka raajada), mugdiga ay keento shucaacu wuxuu wiiqin karaa gudbinta indhaha. Muraayadaha adag ee shucaaca ayaa la heli karaa, laakiin xitaa silica isku dhafan ee caadiga ah waxay muujisaa iska caabin aad u fiican:
- Silica la isku daray: Ma jirto khasaare gudbin oo la qiyaasi karo ilaa wadarta qiyaasta 10 krad
- N-BK7: Lumista gudbinta <1% 400 nm ka dib 1 krad
Xasilloonida Muddada Dheer:
Saamaynta isku-darka ah ee arrimaha kiimikada iyo deegaanka ayaa go'aamisa xasilloonida muddada dheer. Si sax ah loogu hagaajiyo walxaha isku-dhafka ah:
- Silica la isku daray: Xasiloonida cabbirka < 1 nm sannadkii xaaladaha shaybaarka caadiga ah
- Zeduror®: Xasillooni cabbireed < 0.1 nm sannadkii (sababtoo ah xasilinta wejiga kristalinta)
- Aluminium: Wareeg cabbir ah 10-100 nm sannadkii sababtoo ah nasashada walwalka iyo wareegga kuleylka
Codsiga Dhabta ah:
Shirkad dawooyin ah ayaa ku shaqeysa nidaamyada iswaafajinta indhaha si loogu sameeyo kormeer otomaatig ah oo ku yaal jawi nadiif ah oo maalinle ah oo nadiifin ku salaysan IPA ah. Markii hore waxay isticmaaleen qaybaha muraayadaha balaastikada ah, waxay la kulmeen burbur dusha sare oo u baahan beddel lixdii biloodba mar. U beddelashada walxaha galaaska ah ee borofloat®33 waxay kordhisay cimriga qaybaha ilaa in ka badan 5 sano, taasoo hoos u dhigaysa kharashyada dayactirka 80% iyo baabi'inta waqtiga aan la qorsheyn ee ka dhasha burburka indhaha.

Geedi socodka Dhammaystirka Dusha Sare
Shiidida iyo Nadiifinta:
Horumarka laga bilaabo shiididda qallafsan ilaa qurxinta kama dambaysta ah waxay go'aamisaa tayada dusha sare iyo fidsanaanta:
- Shiidida Adag: Waxay ka saartaa walxaha badan, waxayna gaartaa dulqaad dhumuc leh ±0.05 mm
- Shiidid Fiican: Waxay yareysaa qallafsanaanta dusha sare ilaa Ra ≈ 0.1-0.5 μm
- Nadiifinta: Waxay gaartaa dhammaystirka dusha sare ee ugu dambeeya Ra ≤ 0.5 nm
Nadiifinta Pitch-ka iyo Nadiifinta Kumbuyuutarka ee Kontoroolka ah:
Nadiifinta codka ee dhaqameed waxay gaari kartaa fidsanaan λ/20 ah oo ku taal substrate-yada yaryar ilaa kuwa dhexdhexaadka ah (ilaa 150 mm). Substrate-yada waaweyn ama marka loo baahdo wax-soo-saar sare, nadiifinta kombiyuutarrada lagu xakameeyo (CCP) ama dhammaystirka magnetorheological (MRF) waxay awood u siineysaa:
- Fidsanaan joogto ah oo ku wareegsan substrate-ka 300-500 mm
- Waqtiga hawsha oo la dhimay 40-60%
- Awoodda lagu saxayo khaladaadka soo noqnoqda ee bartamaha-meelaha
Habaynta iyo Xidhitaanka Kulaylka:
Sida hore loo soo sheegay, daaweynta saxda ah ee neef-qabatintu waa muhiim si loo yareeyo walbahaarka:
- Heerkulka Qaboojinta: 0.8 × Tg (heerkulka kala-guurka galaaska)
- Waqtiga qoyan: 4-8 saacadood (miisaan leh dhumuc labajibbaaran)
- Heerka qaboojinta: 1-5°C/saacaddii iyada oo loo marayo barta cadaadiska
Muraayadaha CTE-ga hooseeya sida ULE iyo Zeduror, waxaa laga yaabaa in loo baahdo wareeg dheeraad ah oo kuleyl ah si loo gaaro xasillooni cabbir leh. "Hawsha gabowga" ee Zeduror waxay ku lug leedahay wareegga walxaha inta u dhaxaysa 0°C iyo 100°C muddo toddobaadyo ah si loo xasiliyo marxaladda kristalinta.
Hubinta Tayada iyo METrolojiga

Tixgelinta Isdhexgalka: Ku darista Substrate-ka Muraayadaha Nidaamyada Isku-dubaridka
Si guul leh u hirgelinta walxaha muraayadda saxda ah waxay u baahan tahay fiiro gaar ah oo ku saabsan rakibidda, maaraynta kulaylka, iyo xakamaynta deegaanka.
Ku rakibidda iyo rakibidda
Mabaadi'da Ku-xidhka Kinematic-ka:
Si loo helo isku-hagaajin sax ah, substrate-yada waa in lagu rakibaa si kinematic ah iyadoo la adeegsanayo taageero saddex-dhibcood ah si looga fogaado in la keeno cadaadis. Qaabeynta rakibidda waxay ku xiran tahay codsiga:
- Ku rakiban malab: Substrate-yada waaweyn, kuwa fudud ee u baahan adkaansho sare

Khalkhalka uu keeno walbahaarka:
Xitaa iyadoo la adeegsanayo qalabka isku xidhka kinematic-ka, xoogagga isku xidhka ayaa keeni kara qallooc dusha sare ah. Si loogu dulqaado λ/20 fidsanaan ah substrate silica ah oo 200 mm ah, awoodda ugu badan ee isku xidhka waa inaysan dhaafin 10 N oo ku baahsan meelaha taabashada > 100 mm² si looga hortago qallooca oo ka badan qeexitaanka fidsanaan.
Maareynta Kulaylka
Xakamaynta Heerkulka Firfircoon:
Si loo helo isku-habeyn aad u sax ah, xakamaynta heerkulka firfircoon ayaa badanaa lagama maarmaan ah:
- Saxnaanta xakamaynta: ±0.01°C shuruudaha fidsanaan λ/20
- Midaysanaan: < 0.01°C/mm oo ka sarraysa dusha sare ee substrate-ka
- Xasilloonida: Heerkulka oo hoos u dhacaya < 0.001°C/saacaddii inta lagu jiro hawlgallada muhiimka ah
Go'doominta Kulaylka Dadban:
Farsamooyinka go'doominta dadban waxay yareeyaan culeyska kulaylka:
- Gaashaannada kulaylka: Gaashaannada shucaaca ee lakabka badan leh oo leh dahaadh yar oo qiiqa ka soo baxa
- Dahaarka: Alaabada dahaarka kulaylka ee waxqabadka sare leh
- Cufka kulaylka: Isbeddellada heerkulka ee weyn ee kaydiya cufka kulaylka
Xakamaynta Deegaanka
Iswaafajinta Qolka Nadiifinta:
Codsiyada semiconductor-ka iyo kuwa saxda ah ee indhaha, substrates-ku waa inay buuxiyaan shuruudaha qolka nadiifka ah:
- Soo saarista walxaha: < 100 walxood/ft³/daqiiqo (Qol nadiif ah oo fasalka 100 ah)
- Gaaska oo sii daaya: < 1 × 10⁻⁹ Torr·L/s·cm² (loogu talagalay isticmaalka faakuumka)
- Nadiifin: Waa inuu u adkeystaa nadiifinta IPA ee soo noqnoqda iyada oo aan la burburin
Falanqaynta Kharashka-Faa'iidada: Substrates-ka Muraayadaha iyo Beddelka
In kasta oo walxaha galaaska ah ay bixiyaan waxqabad heer sare ah, haddana waxay matalaan maalgashi bilow ah oo sarreeya. Fahmidda wadarta kharashka lahaanshaha ayaa lagama maarmaan u ah xulashada agabka xog ogaal ah.
