Qhov Kev Xav Tau Zoo Tshaj Plaws ntawm Semiconductor Lithography: Vim li cas iav Substrate Xaiv Qhov Teeb Meem
Nyob rau hauv lub ntiaj teb no ntawm semiconductor manufacturing, qhov precision yog ntsuas nyob rau hauv atomic qhov ntev, txhua yam yuav tsum ua nrog kiag li kev ntseeg. Ntawm cov ntsiab lus tseem ceeb tshaj plaws yog cov iav substrates siv hauv cov cuab yeej lithography- daim iav, theem, cov khoom siv kho qhov muag uas yuav tsum muaj kev sib raug zoo zoo txawm tias nyob rau hauv cov kev ua haujlwm hnyav tshaj plaws.
Rau nanometer- nplai lithography, kev xaiv iav substrate ncaj qha cuam tshuam cov txiaj ntsig, qhov tseeb, thiab cov khoom siv lifespan. Qhov kev xaiv tsis ncaj ncees tuaj yeem ua rau qhov tsis txaus ntseeg ntawm cov qauv kev hloov pauv, thermal drift yuam kev, thiab cov cuab yeej siv tsis zoo uas cuam tshuam kev tsim khoom. Tias yog vim li cas cov tuam txhab lag luam semiconductor tau nce ntxiv mus rau cov khoom siv iav siab heev uas tuaj yeem ua kom nrawm nrog lub peb hlis ntuj tsis tu ncua ntawm Moore Txoj Cai.
Phau ntawv qhia no tshawb txog cov kev sib txawv ntawm cov fused silica thiab borosilicate iav substrates, thiab muab kev nkag siab txog engineering los pab koj xaiv txoj cai rau koj cov ntawv thov tshwj xeeb lithography.
Nkag siab txog cov khoom siv tseem ceeb
Ob leeg fused silica thiab borosilicate iav muab cov khoom tshwj xeeb uas ua rau lawv tsim nyog rau kev siv semiconductor lithography, tab sis lawv qhov sib txawv tseem ceeb tsim cov yam ntxwv sib txawv uas yuav tsum tau ua tib zoo xav hauv cov khoom tsim.
Fused silica yog ib qho uas tsis yog -crystalline daim ntawv ntawm silicon dioxide (SiO₂) uas ua los ntawm fusing siab - purity silica xuab zeb ntawm qhov kub siab tshaj 1,800℃. Cov txheej txheem tsim khoom no tsim cov khoom siv tshwj xeeb thermal stability, optical uniformity, thiab tshuaj purity. Fused silica feem ntau hu ua "synthetic quartz iav" kom paub qhov txawv ntawm qhov tshwm sim ntawm crystalline quartz.
Borosilicate iav, los ntawm qhov sib txawv, yog cov dej qab zib -cov kua txiv kab ntxwv iav hloov kho nrog boron oxide additives uas txo cov thermal expansion thiab txhim kho cov tshuaj tiv thaiv.

Qib no ntawm kev kho qhov muag purity kom ntseeg tau tias cov kab teeb laser khaws lawv cov yam ntxwv ntawm txoj kev nthuav dav ntev, tseem ceeb heev rau kev tswj xyuas qhov sib koom ua ke xav tau rau cov txheej txheem lithography siab heev.
Borosilicate iav muab cov khoom siv kho qhov muag zoo rau ntau daim ntawv thov, nrog rau kev sib kis ntawm ib puag ncig 92-95% ib centimeter hauv qhov pom spectrum. Txawm li cas los xij, lub xub ntiag ntawm boron thiab lwm yam kev hloov kho qhia me ntsis xim thiab nthuav tawm ntau dua piv rau fused silica, ua rau nws tsis haum rau siab - ultraviolet thiab tob-ultraviolet daim ntaub ntawv uas muaj nyob rau hauv advanced lithography txheej txheem.
Lwm qhov tseem ceeb parameter yog refractive index homogeneity. Fused silica tuaj yeem tsim nrog qhov ntsuas qhov ntsuas qhov sib txawv me me raws li ± 1 × 10⁻⁶ hla cov khoom loj, qhov tseem ceeb rau kev tswj cov khoom tsis sib xws. Borosilicate iav feem ntau nthuav tawm qhov ntsuas qhov ntsuas qhov sib txawv nyob ib puag ncig ± 5 × 10⁻⁵, qhov kev txiav txim ntawm qhov loj dua, uas tuaj yeem qhia txog kev cuam tshuam ntawm lub ntsej muag uas ua rau kev daws teeb meem lithography.
Rau EUV lithography tshuab uas siv cov khoom siv optics ntau dua li cov khoom siv kho qhov muag, qhov zoo ntawm qhov chaw thiab cov kev xav tau purity yog qhov nruj dua. Fused silica substrates tuaj yeem ua polished rau ultra- cov nplais du tiav nrog cov nqi roughness tsawg dua 0.1 nm RMS, kom ntseeg tau tias qhov tawg me me ntawm cov mos EUV photons. Borosilicate iav tuaj yeem ua tiav qhov ua tiav siab zoo ib yam, tab sis nws qhov qis qis ua rau kev tswj cov kev ua tiav no nyuaj dua nyob rau hauv siab - kev vibration ib puag ncig.
Mechanical Properties: Sib npaug zog thiab ruaj khov
Thaum cov khoom siv thermal thiab kho qhov muag yog qhov tseem ceeb, kev ua haujlwm ntawm cov khoom siv kuj tseem ua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom siv lithography, tshwj xeeb tshaj yog rau cov theem loj thiab cov qauv kev txhawb nqa uas yuav tsum muaj kev ruaj ntseg hauv kev ua haujlwm zoo.
