Chip manufacturing yog lub npe hu ua lub crown jewel ntawm niaj hnub kev lag luam thiab kuj yog ib tug high-end kev lag luam uas Tuam Tshoj yog tsom rau.
Txawm hais tias daim ntawv thov kev lag luam ntawm cov ntaub ntawv polyurethane feem ntau yog siv rau hauv kev lag luam xws li rwb thaiv tsev, rooj tog zaum thiab khoom siv, tsheb, khau thiab khaub ncaws, kuj tseem muaj cov duab ntxoov ntxoo ntawm cov ntaub ntawv polyurethane hauv chip manufacturing - xws li CMP polishing pads.
CMP yog tsim los ntawm chemical polishing thiab mechanical polishing, tab sis tib lub sij hawm nws overcomes lub shortcomings ntawm tsoos mechanical polishing thiab tshuaj polishing.
Cov khoom siv CMP suav nrog peb qhov tseem ceeb: polishing, tu, thiab kis tau tus mob. Thaum lub sijhawm ua haujlwm, lub taub hau polishing nias rau saum npoo ntawm lub wafer kom polished los ntawm kev ntxhib polishing ncoo, thiab ua tiav lub ntiaj teb kev npaj nrog kev pab ntawm polishing kua corrosion, particle kev sib txhuam, polishing pad txhuam, thiab lwm yam.
Cov cuab yeej siv thiab cov khoom siv siv hauv CMP thev naus laus zis suav nrog: tshuab polishing, polishing slurry, polishing ncoo, tom qab-CMP cov cuab yeej tu, polishing endpoint nrhiav thiab cov txheej txheem tswj cov cuab yeej, pov tseg kev kho thiab cov cuab yeej kuaj, thiab lwm yam.
Polishing tshuab, polishing slurry thiab polishing ncoo yog peb lub ntsiab tseem ceeb ntawm cov txheej txheem CMP. Lawv qhov kev ua tau zoo thiab kev sib koom ua ke txiav txim siab theem ntawm qhov smoothness uas CMP tuaj yeem ua tiav. Hauv cov txheej txheem polishing, ob yam khoom tseem ceeb tshaj plaws yog polishing kua thiab polishing ncoo.
CMP polishing pads yuav tsum muaj qhov zoo corrosion kuj, hydrophilicity thiab txhua yam khoom. Feem ntau yog tsim los ntawm nruj cellular polyurethane ua npuas ncauj nrog ib tug qauv ntawm nqaim, high-nam piv grooves. Polyurethane muaj elasticity zoo thiab hnav tsis kam, thiab tuaj yeem tswj tau qhov kev ua haujlwm ruaj khov nyob rau hauv qhov kev txiav txim ntawm cov abrasives tas li. Nyob rau tib lub sijhawm, thaum lub sijhawm polishing txheej txheem, cov micropores (cov khoom siv tshuab thiab cov khoom ntxeem tau dej) ntawm cov tawv nqaij npuas polyurethane polishing pad tuaj yeem muag thiab roughen saum npoo ntawm polishing ncoo, thiab tuaj yeem khaws cov khoom abrasive nyob rau hauv cov ntaub ntawv. polishing kua.
Cov micropores no tseem tuaj yeem sau cov ntaub ntawv tshem tawm, thauj cov kua dej polishing, thiab xyuas kom muaj tshuaj lom neeg corrosion, uas yog qhov zoo rau kev txhim kho polishing uniformity thiab polishing efficiency.
