Cov Qauv thiab Cov Lus Qhia Tshwj Xeeb rau cov khoom siv granite hauv cov khoom sib xws?

Cov khoom siv granite yog dav siv nyob rau hauv cov cuab yeej ua semiconductor vim lawv qhov kev ruaj khov thiab lub siab. Lawv yog lub luag haujlwm los saib xyuas qhov tseeb thiab qhov tseeb ntawm cov txheej txheem sib raug zoo. Txawm li cas los xij, kev ua tau zoo thiab kev ntseeg tau yog nyob ntawm cov qauv granite thiab cov kev qhia tshwj xeeb uas tau nce thaum lawv cov qauv tsim, thiab kev teeb tsa.

Hauv qab no yog qee cov qauv thiab cov kev qhia tshwj xeeb uas yuav tsum muaj adhered rau thaum siv cov khoom siv granite nyob rau hauv cov khoom siv semiconductor:

1. Cov Khoom Siv Hluav Taws Xob: Qhov ntom ntom: Qhov ntom ntawm cov khoom siv granite siv nyob rau hauv kev tsim khoom ntawm granite yuav tsum nyob ib ncig 2.65g / cm3. Qhov no yog qhov ceev ntawm cov khoom siv ntuj granite, thiab nws ua kom muaj txiaj ntsig zoo sib xws thiab kev ntseeg tau nyob rau hauv cov khoom siv granite '.

2. Flatness: flatness yog ib qho ntawm feem ntau ntawm cov khoom tseem ceeb tshaj plaws rau cov khoom siv shanioductor. Lub tiaj tiaj ntawm cov npoo granite yuav tsum nyob hauv qab 0.001 hli / m2. Qhov no ua kom pom tseeb tias cov khoom sib xyaw ua ke yog tiaj thiab theem, uas yog qhov tseem ceeb rau cov txheej txheem kev tsim khoom.

3. Nto Ua tiav: Qhov saum npoo tiav ntawm cov cheebtsam granite yuav tsum yog qhov ua tau zoo, nrog qhov chaw saum npoo av hauv qab 0.4μm. Qhov no kom ntseeg tau tias cov npoo ntawm cov coefficient muaj kev sib txhuam ntawm kev txhuam hniav, uas yog qhov tseem ceeb rau kev ua haujlwm du ntawm cov khoom siv semiconductor.

4. Thermal nthuav tawm coefficient: semiconductor cov khoom siv ntawm kev sib txawv, thiab cov khoom siv granite yuav tsum muaj peev xwm tiv taus thermal hloov tsis muaj deformation. Lub thermal expansion coefficient ntawm granite siv nyob rau hauv cov cuab yeej soobualuct yuav tsum yog qis dua 2 x 10 ^ -6 / ° C.

5. Qhov tsawg kawg kam rau: qhov ntev ntev yog qhov tseem ceeb rau cov khoom ua haujlwm granite '. Lub seem ntev kev kam rau ntawm granite cov Cheebtsam yuav tsum tsis pub dhau ± 0.1mm rau txhua qhov tseem ceeb.

6. Hardness thiab hnav tsis kam: hardness thiab hnav tsis kam yog cov khoom siv tshwj xeeb rau cov khoom siv slicionductor. Granite muaj lub hardness muaj lub hashs ntawm mohs nplai 6-7, ua rau nws cov ntaub ntawv uas tsim nyog siv cov cuab yeej siv cov khoom siv semiconductor.

7. Rwb thaiv cov kev ua tau zoo: Granite Cheebtsam uas siv nyob rau hauv cov cuab yeej semiconduct yuav tsum muaj kev ua kom zoo rwb thaiv tsev kom tiv thaiv kev puas tsuaj rau cov hluav taws xob hluav taws xob. Hluav taws xob tsis kam yuav tsum yog saum 10 ^ 9 ω / cm.

8. Tshuaj Tiv Thaiv: Cov khoom siv granite yuav tsum tau tiv thaiv cov tshuaj uas nquag siv rau cov txheej txheem semiconductor, xws li acids thiab alkalis.

Hauv kev xaus, cov qauv thiab cov kev qhia tshwj xeeb siv nyob rau hauv cov khoom siv semiconduct yog qhov tseem ceeb ntawm cov txheej txheem ua kom paub meej tias, thiab cov txheej txheem nruab rau kom ntseeg tau tias cov khoom siv tau zoo tshaj plaws. Los ntawm ua raws cov qauv no thiab cov kev qhia tshwj xeeb, semiconductor tuam ntxhab tuaj yeem paub tias lawv cov cuab yeej ua tau zoo nce thiab muaj txiaj ntsig.
