Dab tsi yog kev nyab xeeb ua khoom lag luam granite?

Muaj cov khoom siv ua tiav yog siv nyob rau hauv semiconductor cov txheej txheem tsim kho kom hloov silicon wafers rau hauv kev sib xyaw ua ke. Nws suav nrog ntau yam ntawm cov tshuab ntse thiab cov twj uas tau siv los ua ob peb qhov haujlwm tseem ceeb, suav nrog wafer tu, etching, tso tawm, thiab kuaj.

Granite yog qhov tseem ceeb ntawm cov khoom siv tiv thaiv. Cov khoom siv no yog tsim los ntawm cov ntoo granite, uas yog ib lub pob zeb tsis zoo li ntawm Quartz, Feldspar, thiab mika. Granite yog qhov zoo tagnrho rau wafer ua vim nws cov kws kho tshuab tshwj xeeb, thermal, thiab tshuaj lom neeg.

Cov Khoom Siv Neeg Kho Tshuab:

Granite yog ib qho nyuaj thiab cov khoom siv ntom uas tiv thaiv kev hnav thiab deformation. Nws muaj lub zog siab-rau-hnyav piv, uas txhais tau tias nws tuaj yeem tiv taus cov nra hnyav yam tsis muaj kev tawg lossis tawg. Cov cuab yeej no ua rau nws xaiv zoo rau cov khoom siv siab-precision Cheebtsam uas xav tau raug mob heev.

Thermal Khoom:

Granite muaj cov coefficient ntawm thermal nthuav, uas txhais tau tias nws tsis nthuav lossis cog lus tias yuav hloov kub. Cov cuab yeej no ua rau nws cov khoom siv zoo rau siv nyob rau hauv wafer ua khoom siv, qhov twg kub kev tswj hwm yog qhov tseem ceeb.

Tshuaj lom neeg cov khoom:

Granite yog cov tshuaj tiv thaiv zoo heev rau tshuaj corrosion, uas ua rau nws zoo tagnrho rau kev siv nyob rau hauv ib puag ncig muaj kev thaj yeeb. Nws tsis hnov ​​qab nrog cov acids, los yog cov kuab tshuaj, uas ua rau nws xaiv zoo rau kev siv tshuaj lom etching etching siv.

Granite yog ib qho tseem ceeb ntawm cov khoom siv wafer. Lawv tau siv nyob rau hauv ob peb qhov tseem ceeb ntawm cov txheej txheem, suav nrog wafer tu, etching, thiab kev tso nyiaj. Lawv muab ib qho ruaj khov thiab ruaj ruaj rau cov khoom siv, uas ua kom ntseeg tau yog thiab ntseeg tau.

Hauv cov ntsiab lus xaus, muaj kev nyab xeeb cov cuab yeej ua yog qhov tseem ceeb rau kev tsim khoom ntawm cov khoom sib xyaw ua ke, thiab cov cheeb tsam granite hauv nws lub lag luam. Cov khoom siv no yog tsim los ntawm cov ntoo granite, uas muab cov kws kho kom haum, thermal, thiab tshuaj lom neeg uas yog qhov zoo tagnrho rau wafer ua. Cov cheebtsam granite muab cov chaw ruaj khov thiab ruaj ruaj rau cov khoom siv, uas ua kom pom tseeb thiab ntseeg tau.
