Hauv cov khoom siv semiconductor, qhov twg yuav tsum siv cov khoom siv granite?

n lub ntiaj teb ntawm semiconductor manufacturing, meej thiab raug cov cuab yeej yog ib qho tseem ceeb los tsim cov chips zoo.Muaj ntau qhov chaw ntawm lub chaw tsim khoom semiconductor uas yuav tsum tau siv cov ntaub ntawv nrog cov khoom tshwj xeeb kom ntseeg tau tias kev ua haujlwm siab thiab kev ua haujlwm siab.

Ib qho khoom siv uas tau dhau los ua tus qauv ntawm cov khoom siv semiconductor yog granite.Paub txog nws lub zog thiab ruaj khov, granite yog cov khoom siv zoo heev rau kev tsim thiab fabricating cov khoom siv hauv cov khoom siv semiconductor.Nov yog qee qhov ntawm cov khoom siv semiconductor uas feem ntau siv cov khoom siv granite:

1. Cov paib hauv qab

Lub hauv paus daim hlau ntawm cov khoom siv semiconductor yuav tsum tau tiaj tus thiab ruaj khov kom txo qis kev vibrations thiab variations ntawm kub.Thiab granite yog ib qho ntawm ob peb cov ntaub ntawv uas tuaj yeem ua tau raws li cov cai no.Granite yog cov khoom siv ruaj khov uas tiv taus kev kub ntxhov thiab thermal expansion, kom ntseeg tau tias lub hauv paus phaj tuav nws cov flatness thaum lub sij hawm.

2. Cov theem

Cov theem yog cov khoom tseem ceeb hauv cov khoom siv hluav taws xob semiconductor uas ua tau zoo txav mus rau kev tsim khoom xws li wafer positioning, etching, thiab deposition.Granite theem tau dav siv hauv cov khoom siv semiconductor vim lawv qhov siab nruj, tsis tshua muaj thermal expansion, thiab zoo heev damping zog.Nrog rau theem granite, qhov kev txav mus los yog qhov tseeb dua, thiab cov khoom siv muaj kev pheej hmoo tsawg dua.

3. Cov lus qhia tawm

Linear guides yog cov cuab yeej siv tshuab uas muab cov lus taw qhia tawm raws li ob txoj kab sib txuas.Lawv yuav tsum muaj kev ruaj khov thiab meej, thiab granite yog cov khoom siv zoo tshaj plaws rau lub hom phiaj no.Lub siab tawv thiab damping zog ntawm granite ua rau nws yog ib qho kev xaiv nrov rau linear qhia siv nyob rau hauv cov khoom siv semiconductor, ua kom ruaj khov, thiab precision hauv cov txheej txheem tsim khoom.

4. Chucks

Chucks yog siv los tuav thiab ua haujlwm wafers thaum lub sijhawm tsim khoom ntau yam.Granite chucks yog nrov vim lawv flatness thiab thermal stability.Vim tias granite tsis muaj thermal expansion, chucks ua los ntawm cov khoom no tsis warp los yog hloov qhov ntev thaum raug kub hloov.

5. Cov ntawv tshuaj ntsuam xyuas

Cov ntawv tshuaj ntsuam xyuas yog siv los xyuas qhov zoo ntawm cov khoom tsim hauv cov khoom siv semiconductor.Cov phiajcim no yuav tsum tau tiaj tus thiab ruaj khov, thiab tuaj yeem cuam tshuam lub teeb kom raug.Granite lub siab reflectivity, nto flatness, thiab seem stability ua rau nws yog ib tug nrov kev xaiv rau kev soj ntsuam daim hlau nyob rau hauv semiconductor khoom.

Hauv kev xaus, cov ntsiab lus granite tau dav siv rau qhov tseeb hauv cov khoom siv semiconductor, thiab lawv cov kev siv yog npaj kom nthuav dav vim lawv cov khoom zoo heev.Nrog lawv cov siab tawv, tsis tshua muaj thermal expansion, thiab zoo damping zog, granite ntsiab muab qhov yuav tsum tau stability, raug, thiab repeatability rau kev ua hauj lwm nano-scale nyob rau hauv semiconductor khoom.Cov tuam txhab uas tsim cov khoom siv hluav taws xob zoo tshaj plaws tau nqis peev hauv cov ntaub ntawv zoo tshaj plaws los muab lawv cov khoom zoo tshaj plaws rau kev vam meej, thiab granite tseem yog cov khoom siv mus rau vim nws cov khoom zoo thiab kev ntseeg tau.
