Nyob rau hauv qhov chaw ntawm wafer hloov chaw yog cov khoom siv granite siv?

Granite cov ntaub ntawv tau dav siv hauv kev lag luam semiconductor vim lawv cov yam ntxwv zoo, xws li kev ruaj ntseg siab, tsis tshua muaj thermal expansion, thiab siab tiv thaiv corrosion.Cov khoom no ua rau granite yog ib qho khoom siv zoo tshaj plaws rau kev tsim cov khoom siv high-precision hauv kev hloov pauv wafer.

Hauv cov txheej txheem tsim khoom semiconductor, wafer hloov chaw ua lub luag haujlwm tseem ceeb hauv kev thauj cov wafers hla ntau theem ntawm kev tsim khoom.Precision thiab raug yog qhov tseem ceeb ntawm cov txheej txheem no, txawm tias qhov sib txawv me ntsis tuaj yeem ua rau tag nrho cov txheej txheem.Yog li ntawd, cov khoom siv hauv kev hloov pauv wafer yuav tsum tau ua los ntawm cov ntaub ntawv zoo, thiab granite ua tau raws li cov qauv no.

Qee qhov chaw ntawm kev hloov pauv wafer uas yog tsim los ntawm cov ntaub ntawv granite suav nrog:

1. Nqus Chuck Rooj

Lub tshuab nqus tsev chuck lub rooj yog siv los tuav lub wafer thaum lub sijhawm ua haujlwm, thiab nws yuav tsum muaj qhov chaw ruaj khov kom ntseeg tau tias lub wafer tsis puas.Granite yog ib qho khoom siv zoo tshaj plaws rau kev ua cov rooj no vim nws muaj lub tiaj tus, tsis muaj qhov ntxeem tau uas muab kev ruaj ntseg thiab precision.Tsis tas li ntawd, granite muaj cov coefficient tsawg ntawm thermal expansion, ua rau nws tiv taus qhov kub thiab txias hloov uas tuaj yeem ua rau muaj qhov hloov pauv ntawm qhov wafer.

2. Cua-Bearing Theem

Cov txheej txheem huab cua yog siv los thauj cov wafer los ntawm ntau theem ntawm kev tsim khoom.Lub theem yog engineered los muab ib tug frictionless txav, uas yuav tsum tau high precision thiab stability.Granite yog siv rau hauv daim ntawv thov no vim nws yog lub pob zeb tawv thiab tawv, thiab nws tiv taus deformation thiab hnav dhau sijhawm.

3. Cov lus qhia kev taw qhia

Cov kab ntawv qhia kev taw qhia yog siv los coj cov txheej txheem huab cua, thiab lawv yuav tsum tau muab tso rau kom raug kom txo tau qhov yuam kev.Granite yog siv los tsim cov lus qhia no vim nws muaj kev ruaj ntseg zoo heev thiab lub zog.Cov khoom siv kuj yog corrosion-resistant, uas ua kom lub neej ntev ntawm cov lus qhia.

4. Cov khoom siv hauv xov tooj cua

Cov cuab yeej siv hluav taws xob siv los ntsuas qhov ntev thiab cov khoom ntawm wafer thaum lub sijhawm tsim khoom.Granite yog ib qho khoom siv zoo tshaj plaws rau kev tsim cov cuab yeej no vim tias nws muaj qhov nruj nruj, tsis tshua muaj kev nthuav dav, thiab kev deformation tsawg heev hauv kev thauj khoom.Ntxiv mus, granite lub thermal stability xyuas kom meej tias cov khoom siv metrology tseem ruaj khov thiab raug raws sijhawm.

Hauv kev xaus, kev lag luam semiconductor tso siab rau qhov tseeb thiab qhov tseeb, thiab cov ntaub ntawv granite tau ua pov thawj tias muaj kev ntseeg siab thiab ruaj khov hauv kev tsim khoom.Nrog rau ntau yam tseem ceeb nyob rau hauv lub wafer hloov system yuav tsum muaj kev ruaj ntseg, precision, thiab tsawg thermal expansion, engineers tau tig mus rau granite cov ntaub ntawv kom tau raws li cov kev cai tseem ceeb.
