Kwihlabathi lolawulo lwentshukumo oluchanekileyo kakhulu, kukho into eyenza into evakala ngathi ayiqhelekanga: inqanaba lokuchaneka elidada kwifilimu yomoya enobukhulu obuncinci be-microns, lihamba ngaphandle kokungqubana. Le ayisiyonto yesayensi. Yi-granite air bearing—kwaye yitekhnoloji evumelayo emva kwe-semiconductor lithography, ukuhlolwa kwe-wafer, ukuhlolwa kwebhetri ye-EV, kunye nazo zonke ezinye iinkqubo ezifuna indawo yenqanaba le-nanometer.
Yintoni i-Air Bearing?
I-air bearing isebenza ngokunyanzela umoya ocinezelweyo kumphezulu onemingxuma okanye otyalwe yi-orifice, idala umqamelo womoya obhityileyo noqhubekayo phakathi kweendawo ezimbini ebezinokuthi zinxibelelane ngokwasemzimbeni. Umthwalo—iqonga, i-spindle, itafile ehambayo—uyadada kule filimu yomoya, ngesiqhelo phakathi kwe-5 kunye ne-20 microns ubukhulu, kuxhomekeke kuyilo kunye neemfuno zomthwalo.
Ngenxa yokuba akukho kudibana komzimba phakathi kwezinto ezihambayo nezimiyo, akukho kungqubana koomatshini, akukho kuziphatha kokunamathela, kwaye akukho kuguga. Le yimeko eyahlukileyo ngokupheleleyo kwiibhereji yesixhobo esiqhelekileyo, enokuthi—kungakhathaliseki ukuba yenziwe kakuhle kangakanani na—isoloko inezinga elithile lokungqubana, ukungalungelelani komphezulu ngemicroscope, kunye nokuwohloka kancinci kancinci ngexesha lokusebenza kwayo.
Kutheni iGranite yeyona ndlela ikhethekileyo yokukhetha ii-Air Bearings
Iibheringi zomoya zinokwakhiwa ngokwethiyori kwizinto ezahlukeneyo ezithe tyaba neziqinileyo, kodwa igranite iye yaba lukhetho oluqhelekileyo kumphezulu weebheringi ezimiyo kwizicelo ezichanekileyo.
Uzinzo Lokuthe Tye Ngokuhamba Kwexesha. Ngenxa yokuba i-granite inoxinzelelo lwangaphakathi oluphantsi kakhulu xa ithelekiswa nesinyithi esenziwe ngomatshini—isinyithi sigcina uxinzelelo olushiyekileyo kwinkqubo yokubumba nokulungisa, olunokubangela utshintsho oluncinci kancinci ngokuhamba kweenyanga okanye iminyaka—umphezulu we-granite bearing udla ngokubamba iinkcukacha zawo zokuthe tye ixesha elide kakhulu kune-metal equivalent. Kwi-air bearing, apho yonke i-performance envelope ixhomekeke ekugcineni i-gap ehambelanayo nelawulwayo, olu zinzo lubalulekile.
Uzinzo lobushushu. Umsantsa womoya othwala umoya uncinci kakhulu—ngokuvamile ufikelela kwii-microns ezi-5–20. Ukwandiswa kobushushu bereli yesikhokelo kutshintsha lo msantsa, kutshintsha ukusebenza kwebheri kwaye kuzise iimpazamo zokubeka. I-CTE yeGranite iphantse ibe sisiqingatha sentsimbi kunye nesinye kwisithathu se-aluminium. Oku kuqinisekisa ukuba ukuchaneka kokubeka kwinqanaba le-nanometer kuyasebenza kwimijikelo yokusebenza yeeyure ezingama-24.
Ukudambisa kunye nokuDidliza. I-Granite inomthamo wendalo wokudambisa ophindwe kalishumi kunentsimbi. Xa idityaniswe nokudambisa okuxineneyo kwefilimu yomoya, inkqubo idala isiphumo "sokudambisa kabini" esahlula imithwalo ebuthathaka kwiintshukumo zomgangatho kunye nengxolo yemoto. Oku kubalulekile kwizicelo ezifana neekholamu zemitha ye-electron kunye nee-interferometers, apho ukudlidliza kutshabalalisa isisombululo somfanekiso.
AyinaMagnetic, Ayisebenzi Ngombane. Kwiindawo zokuvelisa i-semiconductor kunye ne-elektroniki, ukuphepha amasimi emagnethi kunye nokuqhuba umbane kufutshane neenkqubo ezinobuthathaka kudla ngokuba yimfuneko enzima. I-Granite iyahlangabezana nale mfuneko ngaphandle konyango olongezelelweyo.
Isiphumo "sokuDambisa kabini"
Nantsi into eyenza indibaniselwano yegranite-air bearing isebenze ngendlela ekhethekileyo. Igranite ngokwayo inika ukudambisa okumangalisayo—inciphisa ingxolo yomatshini ukuya kuthi ga kwi-10 xa ithelekiswa nentsimbi ephoswe ngentsimbi. Ifilimu yomoya inika ukudambisa okongezelelweyo okunamandla, ilungisa ukungcangcazela okuphezulu. Xa zidibene, zenza oko iinjineli zikubiza ngokuba yi-"double-damping".
Oku kuthetha ukuba inqanaba lokuthwala umoya wegranite alichanekanga nje kuphela; lithule. Inqanaba lihamba kakuhle, ngaphandle kokushukuma okuncinci okuchaphazela iibheringi zoomatshini. Lihlala ngokukhawuleza, ngaphandle kokukhala okunokulibazisa ukulinganisa. Kwaye ligcina ukuchaneka kwalo kwiminyaka yokusebenza, ngaphandle kokuguguleka kancinci kancinci okonakalisa ukusebenza kweebheringi zoomatshini.
Apho Iibheringi Zomoya ZeGranite Zisetyenziswa Khona Ngokwenene
Uluhlu lwezicelo lufana nohambo oluya kwiindawo ezichanekileyo kakhulu zokwenza nokuhlola izinto zanamhlanje:
I-Semiconductor Lithography kunye nokuhlolwa kweWafer. Ukuphindaphinda kokubekwa kwe-sub-nanometer kuyafuneka ukuze kuhambelane iimpawu ngokuchanekileyo kwi-wafer. Iibheringi zomoya zegranite zibonelela ngentshukumo engenakuphikiswa, engadibaniyo evumela ukuchaneka okufunekayo kwimveliso yeetshiphusi zesizukulwana esilandelayo.
IiCoordinate Measuring Machines (CMMs). Ukudibanisa izikhokelo zegranite ezichanekileyo kunye nee-air bearings ngumgangatho ogqwesileyo we-CMMs, apho ukungcangcazela kwesigaba kutshabalalisa isisombululo sokulinganisa. Ukungabikho kokungqubana kunye nokutyibilika kwe-stick bearing kwenza ukuba kubekho indawo kwi-nanometer increments.
Iinkqubo zokulinganisa ezisekwe kwi-Optical kunye ne-Laser. Nayiphi na inkqubo yokulinganisa exhomekeke kwi-interferometry okanye kwi-optical imaging ifuna inqanaba lokuhamba elingavezi impazamo yokungcangcazela okanye yokuma. Iibheringi zomoya zegranite zibonelela ngozinzo olufunekayo kwezi zicelo zinzima.
Ukuhlolwa kwebhetri ye-EV. Njengoko imveliso yebhetri yesithuthi sombane isanda, imfuno yeenkqubo zokuhlola ezikhawulezayo nezichanekileyo ikhule kakhulu. Amanqanaba okuthwala umoya wegranite abonelela ngesantya kunye nokuchaneka okufunekayo ekuhloleni ubukhulu beeseli zebhetri, ukulungelelaniswa kwe-electrode, kunye nezinye iiparameter ezibalulekileyo.
Ukubhola kunye nokuHamba nge-PCB. Ukubhola nge-PCB ngesantya esiphezulu kufuna indawo ekhawulezileyo nechanekileyo kunye nexesha elincinci lokuzinza. Iibheringi zomoya zivumela intshukumo ekhawulezayo yokunyathela kunye nokuzinza efunekayo kwimveliso ephezulu.
Yintoni Eyahlula iZHHIMG®
Ayizizo zonke izinto ezithwala umoya zegranite ezilinganayo. Umgangatho wegranite, ukuchaneka kokulepha, kunye nobuchule beengcibi zonke ezigqiba ukuba i-air bearing isebenza ngokweemfuno.
Kwi-ZHHIMG®, i-granite yethu emnyama ye-ZHHIMG® ifikelela kuxinano lwe-≈3100 kg/m³—iphezulu kunee-granite ezininzi ezimnyama zaseYurophu naseMelika—iqinisekisa uzinzo oluphezulu kunye nokumelana nokuguguleka. Iigrinder zethu eziphambili, ezinamava angaphezu kweminyaka engama-30 okusebenzisa isandla, zifikelela kwinqanaba le-nanometer elifunekayo kwizicelo zokuthwala umoya.

Kwaye ukuzibophelela kwethu kumgangatho—okushwankathelwe kumgaqo-nkqubo wethu womgangatho, “Ishishini elichanekileyo alinakuba nzima kakhulu”—kuqinisekisa ukuba yonke into ethwala umoya wegranite ephuma kwiziko lethu ihlangabezana nemigangatho yehlabathi enzima kakhulu.
Nokuba wakha isizukulwana esilandelayo sezixhobo ze-semiconductor lithography, i-CMM echanekileyo kakhulu, okanye inkqubo yokuhlola ibhetri ye-EV, indibaniselwano ye-precision granite kunye netekhnoloji yokuthwala umoya inika isiseko solawulo lwentshukumo yenqanaba le-nanometer. Kwaye kwi-ZHHIMG®, besisoloko siyiqonda loo ndibaniselwano kangangeminyaka emininzi.
