Nyob rau hauv high -}}} end tsim kev lag luam xws lisemiconductors, aerospace, thiab khoom siv kho mob, Nto roughnessthiabParticle Particleyog qhov tseem ceeb rau cov khoom lag luam tsis txaus ntseeg. European thiab American cov neeg siv khoom feem ntau yuav tsum tau muaj kab noj hniav sab hauv thiab cov kua dej seev cev kom ua tiav qhov chaw ntawmRa tsawg dua los yog sib npaug rau 0.2-0.4 μm, thaum ua kom paub meejtsis muaj particle sheddingCov. Qhov no yuav tsum tau ua rau muaj kev ci ntsa iab thiab ncaj qha cuam tshuam rau kev ua haujlwm thiab kev ntseeg tau ntawm cov khoom siv.
Piv txwv li, nyob rau hauv kev lag luam semiconduct, residual micro - Cov nplais hauv cov kab noj hniav thiab cov kua dej ncig ua si, muaj peev xwm ua rau muaj peev xwm ua tauWafer tsis xws luagthiab kev poob nyiaj txiag tseem ceeb. Yog li ntawd, Cheebtsam yuav tsum yauv musUltra - precure polishing, Kev tu kom nruj, thiabCov Ntsuas Xyuas Cov Ntawv Qhia TawmTxhawm rau kom ntseeg tau cov particle - tsis muaj qhov chaw dawb.
Hauv kev sib piv, qee qhov kev ua haujlwm hauv tsev tseem cia siab rau "Ci ntsa iab yog qhov txaus siab txaus" kev sib deev, saib xyuas dhau losQuantitative Sab Deg Roughness TswjthiabKev tshuaj ntsuam xyuas kev pheej hmooCov. Qhov kev sib pauv no yog qhov kev txhawj xeeb tseem ceeb rau cov neeg siv khoom hauv cov neeg muag khoom hauv cov neeg muag khoom.
Npis Xus Precisionmuaj kev paub ntau hauv daim teb no. Peb tuaj yeem tswj tauCov kev xav tau saum npoo kom ua tau raws li cov neeg siv nruj thaum lub caij ultras - precision polishing, thiab siv kev tu thiab tshuaj xyuas cov txheej txheem los xyuas kom muaj cov khoom siv ncav cuagCov Qauv Huv Huv HuvCov. Qhov no tsis yog tuaj yeem lav kev ua haujlwm ruaj khov tab sis kuj muab cov neeg siv nyiaj koom kev ntseeg siab rau high- kev pheej hmoo cov ntawv thov hla, aerospace, thiab kev lag luam kho mob.
