Kuchinja kwekugadzirisa michina ye lithography hakuwanzoonekwa sekukundikana kamwe chete. Kunoonekwa zvishoma nezvishoma - kukanganisa kwe overlay kunopinda kunze kwe spec pane mamwe ma shifts, kana kuti kudzokorora kwakanaka mangwanani uye kunokatyamadza masikati. Mugadziri wemidziyo ye semiconductor paakauya kwatiri ne pattern iyoyo chaiyo pa gantry-based exposure system, pfungwa yavo yaive yekutarisa optics ne stage motors kutanga. Pfungwa ine musoro - idzi dzinowanzo fungidzirwa. Muchiitiko ichi, hwaro hwe structural base pasi pe gantry hwakazove hwakabatsira zvikuru kupfuura zvaitarisirwa nemunhu wese.
Dambudziko reKurongeka
Midziyo iyi yaishandisa furemu yesimbi yakasungirirwa kuti ifambise musoro we optical pamusoro pe envelopu yebasa. Papepa, furemu yakasangana nekushivirira kwayo kusingachinji. Zvisinei, mukugadzira, mugadziri aiona kukanganisa kwe overlay kwaienderana zvishoma nezvishoma nenguva yezuva uye kushanduka kwekushisa-pasi pechitoro - maitiro airatidza kuwedzera kwekupisa kwete kukanganisa kwemakanika kana kuti control-system. Kuwanda kwekuwedzera kwekupisa kwesimbi, pamwe chete nekugadzirwa kwe welded kwefuremu, zvaireva kuti gantry span pachayo yaifamba nekashoma asi chaiyo sezvo tembiricha ye ambient ichichinja kuburikidza nezuva rekugadzirwa rakajairika. Pa system apo sub-micron alignment ndiyo inodiwa yekutanga, microns shoma dzekufamba kwechimiro chisina kuverengerwa zvakakwana kusundira overlay error kunze kwe spec nguva nenguva - inova ndiyo mhando chaiyo yedambudziko rinogara kwenguva pfupi, rakaoma kuongororwa rinodya mavhiki enguva yeinjiniya munhu asati abvunza furemu.
Chikonzero nei Granite Yaiva Mhinduro Yekuvaka
Kutsiva gantry yesimbi yakasungirirwa negranite yakafanana hakusi kuchinjana kwakafanana - kunochinja fungidziro yedhizaini. Kuwanda kwekuwedzera kwekupisa kweGranite uye damping coefficient yakakwira zvaireva kuti chimiro chaizopindura zvishoma nezvishoma uye zvisina kusimba kune kushanduka kwemamiriro akafanana. Zvakafananawo: granite haina kushushikana kwemukati kwakasara sezvinoita furemu yesimbi yakasungirirwa, saka hairambe ichikwira zvishoma nezvishoma mumakore ekupisa sezvinoita chivakwa chesimbi chakagadzirwa.
Dambudziko reinjiniya rakanga risiri rekusarudza zvinhu asi rekuita - danda rebhiriji rakafukidza bhaudhi remuchina raifanira kugadzirwa sechimiro chakareba, chine chidimbu chimwe chete kudzivirira kuisa majoini aizounzazve kusagadzikana kwegranite kwaifanira kugadziriswa. Iro idambudziko rekugadzira zvinhu; havasi vese vagadziri vegranite vanogona kugadzirisa danda rehurefu hwakadaro nehuremu hwakadaro kusvika pahurefu hwakakodzera uye hwakaenzana mune imwe chete. Kugona kwenzvimbo yedu kugadzira chidimbu chimwe chete.zvikamu zvegranitekureba kwemamita makumi maviri kwakaita kuti zvive nyore kuibatanidza pane kuda kuti ive yakakamurwa, yakabatana.
Ruzivo rweKushandiswa
Beam remuchina rakapedzwa ne "optical mounting interfaces" yemutengi yakasungirirwa zvakananga mu granite, ichibata kugadzikana uye kushivirira kwakaringana zvichienderana nebhajeti re "exposure system alignment". Kupedzisa pamusoro kwakatevera cheni imwechete yekuyera yakashandiswa mu granite reference tooling yedu - yakaenzaniswa nemidziyo inoteverwa neNational Metrology Institute Standards - saka kuongororwa kwemutengi kwaive nemagwaro anoenderana, pane kuda kuongorora zvakare kugadzikana usati waisa.
Kurema kwaive chinhu chechipiri chakakodzera kutaurwa zvechokwadi: granite yakakora kupfuura chikamu chesimbi chakaenzana, uye mota dzemutengi dzedanho uye chimiro chekutsigira zvinodiwa kuti zvigamuchirwe nemusiyano iwoyo. Uku kutengeserana chaiko kwemagadzirirwo egranite gantry, kwete chinhu chekusaziva - mabhenefiti ekupisa uye damping anouya nemutengo mukuru unofanirwa kugadziriswa pane kuregeredzwa.
Mhedzisiro
Mushure mekuiswa, mutengi akataura kuti kukanganisa kwe overlay kwakanga kusisina kuteverwa nenguva yezuva kana tembiricha yekunze sezvayakanga yakaita kare - hukama hwairatidza kudonha kwekupisa mukuongorora kwekutanga hwakanyangarika zvakanyanya. Kudzokororwa kwemashifts kwakava kwakafanana, izvo zvaikosha zvakanyanya pakushanda kupfuura chero nhamba imwe chete ye peak-acurate, sezvo goho rekugadzira rinoenderana nekuenderana kwese pane kuyerwa kwakanakisa.
Zvinotaurwa Nenyaya Iyi Zvakanyanya
Zvinhu zvekuvaka zviri nyore kufuratira mukugadzirisa matambudziko e alignment nekuti hazviwanzo fungidziro yekutanga - optics, control loops, uye stage mechanics zvinotanga kupomerwa mhosva, uye dzimwe nguva nemazvo. Asi kana drift ikabatana netembiricha pane load kana motion pattern, furemu pachayo inofanirwa kutariswa isati yashandiswa nguva yakawanda kugadzirisa masisitimu asina kumbobvira anetsa. Granite gantry uye bridge structures hazvisi zvepasi rose, uye hazvisi mhinduro chaiyo yemhando yega yega yemidziyo - asi kune mashandisirwo apo thermal stability inosarudza zvakananga goho, zvakakodzera kuongororwa pakutanga mukuita kwekuongorora kupfuura zvazvinowanzoita.
