Kusinthasintha kwa zida za lithography nthawi zambiri sikumadziwonetsa ngati kulephera kamodzi kokha. Kumawonekera pang'onopang'ono - cholakwika cha overlay chikupita kunja kwa spec pakusintha kwina, kapena kubwerezabwereza komwe kumakhala bwino m'mawa komanso kokayikitsa masana. Pamene wopanga zida za semiconductor adatifikira ndi mawonekedwe omwewo pamakina owonetsera omwe ali ndi gantry, chibadwa chawo chinali kuyang'ana kaye ma optics ndi ma siteji motors. Chidziwitso choyenera - nthawi zambiri amenewo ndi omwe amakayikiridwa. Pankhaniyi, maziko a kapangidwe kake pansi pa gantry adapezeka kuti ndi ofunikira kwambiri kuposa momwe aliyense amayembekezera.
Vuto la Kugwirizana
Zipangizozo zinagwiritsa ntchito chimango cha gantry chachitsulo cholumikizidwa kuti chinyamule mutu wa kuwala kudutsa mu envelopu yogwirira ntchito. Papepala, chimangocho chinakwaniritsa kulekerera kwake kosasinthasintha. Komabe, popanga, wopanga anali kuwona cholakwika cha overlay chomwe chimagwirizana pang'ono ndi nthawi ya tsiku ndi kusintha kwa kutentha kwa shopu - mawonekedwe omwe ankaloza ku kukula kwa kutentha osati vuto la makina kapena dongosolo lowongolera. Kuchuluka kwa kutentha kwa Steel, kuphatikiza ndi kapangidwe ka thermal ka chimango, kunatanthauza kuti gantry span yokha inali kuyenda pang'ono koma yeniyeni pamene kutentha kwamlengalenga kunasintha tsiku lokhazikika lopangira. Pa dongosolo lomwe sub-micron alignment ndiye chofunikira choyambirira, ma microns ochepa a kayendedwe ka kapangidwe kosawerengedwa ndi okwanira kukankhira cholakwika cha overlay kuchoka pa spec nthawi ndi nthawi - chomwe ndi mtundu wa vuto losakhazikika, lovuta kuzindikira lomwe limadya milungu ingapo ya nthawi yaukadaulo aliyense asanafunse chimangocho.
Chifukwa Chake Granite Inali Yankho Lachilengedwe
Kusintha gantry yachitsulo cholumikizidwa ndi granite sikusinthana kwa kufanana - kumasintha malingaliro a kapangidwe kake. Kuchuluka kwa kutentha kwa granite komanso kuchuluka kwa kutentha kwa granite kumatanthauza kuti kapangidwe kake kangayankhe pang'onopang'ono komanso mochepa kwambiri ku kusinthasintha komweko kwa mlengalenga. Zofunikanso: granite simakhala ndi zotsalira zamkati zomwe chimango chachitsulo cholumikizidwa chimakhala nazo, kotero sichimapitirira kukwera m'magawo kwa zaka zambiri zozungulira kutentha monga momwe kapangidwe kachitsulo kopangidwa kangachitire.
Vuto la uinjiniya silinali kusankha zinthu koma kuchita - mtanda wa mlatho wozungulira womwe unali mkati mwa envelopu yonse yogwirira ntchito ya chipangizocho unkafunika kupangidwa ngati kapangidwe kakatali, ka chidutswa chimodzi kuti tipewe kuyambitsa maulumikizidwe omwe angabwezeretse kusakhazikika kwa granite komwe kumayenera kuthetsedwa. Limenelo ndi funso la mphamvu yopangira makina komanso la zipangizo; si wopanga granite aliyense amene angathe kukonza mtanda wautali ndi kulemera koteroko mpaka kufika pamlingo wofunikira komanso wofanana mu dongosolo limodzi. Kuthekera kwa malo athu opangira makina a chidutswa chimodzizigawo za graniteKutalika kwa mamita 20 kunapangitsa kuti izi zikhale zosavuta kulumikiza m'malo mofuna mgwirizano wogawanika komanso wogwirizana.
Tsatanetsatane wa Kukhazikitsa
Mzere wa gantry unamalizidwa ndi ma interfaces a kasitomala optical mounting omwe anapangidwa mwachindunji mu granite, kusunga kusalala ndi kulekerera kolunjika mogwirizana ndi bajeti yonse ya dongosolo lowonetsera. Kumaliza pamwamba kunatsatira unyolo womwewo woyezera womwe umagwiritsidwa ntchito pa zida zathu zowunikira granite — wolinganizidwa motsutsana ndi zida zomwe zikutsatira miyezo ya bungwe la metrology — kotero kuyang'anira komwe kukubwera kwa kasitomala kunali ndi zikalata zofananira, m'malo mofunika kutsimikiziranso kusalala asanayike.
Kulemera kunali chinthu chachiwiri chomwe chiyenera kuganiziridwa moona mtima: granite ndi yokhuthala kuposa gawo lofanana la chitsulo, ndipo injini za kasitomala ndi kapangidwe kothandizira zimafunika kuti zigwirizane ndi kusiyana kumeneko. Uku ndi kusinthana kwenikweni kwa mapangidwe a granite gantry, osati chinthu choti chisawonekere - ubwino wa kutentha ndi chinyezi umabwera ndi chilango chachikulu chomwe chiyenera kukonzedwa m'malo monyalanyazidwa.
Zotsatira
Pambuyo poyika, kasitomala adanenanso kuti cholakwika cha overlay sichinatsatidwenso ndi nthawi ya tsiku kapena kutentha kwa mlengalenga monga momwe zinalili kale - mgwirizano womwe unkawonetsa kusinthasintha kwa kutentha mu matenda oyamba unatha kwambiri. Kubwerezabwereza pakati pa kusinthana kunakhala kofanana, komwe kunali kofunika kwambiri kuposa nambala iliyonse yolondola kwambiri, popeza phindu la kupanga limadalira kusinthasintha pakati pa kuthamanga konse m'malo moyesa bwino kwambiri.
Zimene Nkhaniyi Ikupereka Mwambiri
Zinthu zoyambira za kapangidwe kake n'zosavuta kuzinyalanyaza pothetsa mavuto chifukwa nthawi zambiri sizimakhala zokayikitsa koyamba - ma optics, ma control loops, ndi ma stage mechanics omwe amayamba kudzudzulidwa, ndipo nthawi zina molondola. Koma pamene kutsetsereka kwa magetsi kukugwirizana ndi kutentha osati momwe katundu kapena kayendedwe kake kamayendera, chimangocho chiyenera kuyang'aniridwa nthawi yochulukirapo isanathe kukonza makina omwe sanali vuto lenileni. Ma granite gantry ndi ma bridge structures si njira yodziwika bwino, ndipo si yankho lolondola pa kalasi iliyonse ya zida - koma pa ntchito zomwe kukhazikika kwa kutentha kumatsimikizira mwachindunji kuchuluka, ziyenera kuyesedwa kale mu njira yodziwira matenda kuposa momwe zimakhalira nthawi zambiri.
