Granite Cheebtsam yog siv dav hauv cov khoom siv semiconductor vim lawv qhov ruaj khov thiab ua haujlwm ntev.Lawv yog lub luag haujlwm rau kev tswj xyuas qhov tseeb thiab qhov tseeb ntawm cov txheej txheem tsim khoom semiconductor.Txawm li cas los xij, qhov ua tau zoo thiab kev ntseeg siab ntawm cov khoom siv granite nyob ntawm cov qauv thiab cov lus qhia tshwj xeeb uas tau txais kev txhawb nqa thaum lawv tsim, tsim, thiab teeb tsa.
Cov hauv qab no yog qee cov qauv thiab cov kev qhia tshwj xeeb uas yuav tsum tau ua raws li thaum siv cov khoom siv granite hauv cov khoom siv semiconductor:
1. Khoom ntom ntom: Qhov ntom ntawm cov khoom siv granite siv hauv kev tsim cov khoom siv granite yuav tsum nyob ib ncig ntawm 2.65g / cm3.Qhov no yog qhov ceev ntawm cov khoom siv granite ntuj, thiab nws ua kom zoo ib yam thiab kev ntseeg siab hauv cov khoom siv granite 'cov khoom.
2. Flatness: Flatness yog ib qho tseem ceeb tshaj plaws ntawm cov khoom siv granite siv hauv cov khoom siv semiconductor.Qhov flatness ntawm granite nto yuav tsum qis dua 0.001 mm / m2.Qhov no ua kom ntseeg tau tias cov khoom ntawm qhov chaw tiaj tus thiab theem, uas yog qhov tseem ceeb rau cov txheej txheem tsim khoom semiconductor.
3. Nto Finish: Qhov saum npoo ntawm cov khoom siv granite yuav tsum yog qhov zoo, nrog rau qhov roughness hauv qab 0.4µm.Qhov no ua kom ntseeg tau tias qhov chaw ntawm granite tivthaiv muaj qhov coefficient ntawm kev sib txhuam, uas yog qhov tseem ceeb rau kev ua haujlwm du ntawm cov khoom siv semiconductor.
4. Thermal Expansion Coefficient: Cov khoom siv semiconductor ua haujlwm ntawm qhov sib txawv ntawm qhov kub thiab txias, thiab cov khoom siv granite yuav tsum tuaj yeem tiv taus thermal hloov pauv yam tsis muaj deformation.Lub thermal expansion coefficient ntawm granite siv hauv cov khoom siv semiconductor yuav tsum qis dua 2 x 10^-6 / ° C.
5. Dimensional kam rau ua: Dimensional kam rau ua yog ib qho tseem ceeb rau granite Cheebtsam 'kev ua tau zoo.Qhov ntev ntev ntawm cov khoom siv granite yuav tsum tsis pub dhau ± 0.1 hli rau txhua qhov loj me.
6. Hardness thiab Wear Resistance: Hardness thiab hnav tsis kam yog qhov tseem ceeb ntawm cov khoom siv granite siv hauv cov khoom siv semiconductor.Granite muaj qhov nyuaj ntawm Mohs Scale 6-7, ua rau nws yog ib qho khoom siv tsim nyog rau kev siv cov khoom siv semiconductor.
7. Rwb thaiv tsev Performance: Granite Cheebtsam siv nyob rau hauv semiconductor khoom yuav tsum muaj zoo rwb thaiv tsev kev ua tau zoo los tiv thaiv kev puas tsuaj rau rhiab hluav taws xob Cheebtsam.Hluav taws xob kuj yuav tsum siab tshaj 10 ^ 9 Ω / cm.
8. Chemical Resistance: Granite Cheebtsam yuav tsum tiv taus cov tshuaj nquag siv hauv cov txheej txheem tsim khoom semiconductor, xws li acids thiab alkalis.
Hauv kev xaus, cov qauv thiab cov lus qhia tshwj xeeb rau granite cov khoom siv hauv cov khoom siv semiconductor yog qhov tseem ceeb los xyuas kom meej lub neej ntev thiab kev ntseeg tau ntawm ob qho tib si cov khoom thiab cov khoom siv uas lawv tau siv. cov txheej txheem los xyuas kom meej tias cov khoom yog cov zoo tshaj plaws.Los ntawm kev ua raws li cov qauv no thiab cov lus qhia tshwj xeeb, cov tuam txhab lag luam semiconductor tuaj yeem ua kom ntseeg tau tias lawv cov cuab yeej ua haujlwm tau zoo, ua rau muaj txiaj ntsig thiab muaj txiaj ntsig zoo.
