Yuav ua li cas txog kev hnav tsis kam thiab kev ua haujlwm ntev ntawm cov khoom granite hauv cov khoom siv semiconductor?

Granite yog ib qho kev xaiv nrov rau kev siv hauv cov khoom siv semiconductor vim nws lub zog ruaj khov thiab tiv taus kev hnav. Cov yam ntxwv no yog qhov tseem ceeb vim tias cov chaw ua haujlwm semiconductor paub txog lawv cov xwm txheej hnyav uas suav nrog qhov kub siab, cov tshuaj lom neeg corrosive, thiab kev ntxhov siab tas li. Cov khoom siv granite tuaj yeem tiv taus cov xwm txheej hnyav no yam tsis muaj kev tawg, chipping lossis lwj dhau sijhawm, yog li ua rau lawv yog qhov kev daws teeb meem zoo tshaj plaws rau cov ntawv thov zoo li no.

Qhov tawv ntawm granite ua rau nws tiv taus kev hnav thiab tsim kua muag, thiab cov khoom siv tuaj yeem tiv taus kev txav mus los ntawm cov khoom siv sib txawv hauv cov khoom siv semiconductor yam tsis raug puas tsuaj. Cov khoom granite kuj tseem ruaj khov txawm tias raug rau cov tshuaj lom neeg siv hauv qhov chaw tsim khoom semiconductor. Qhov no yog vim muaj qib siab ntawm qhov ceev thiab qib qis ntawm porosity, uas txhais tau tias cov granite khov kho tsis pub cov tshuaj lom neeg nkag mus.

Vim lawv cov khoom siv uas tsis yooj yim puas, cov khoom siv granite tuaj yeem siv tau ntau xyoo hauv cov khoom siv semiconductor, yam tsis tas yuav hloov. Qhov no txhais tau tias cov chaw tsim khoom semiconductor tuaj yeem tau txais txiaj ntsig los ntawm kev kho tsawg dua thiab txo qhov xav tau kev saib xyuas, piv rau lwm cov khoom siv xaiv. Tsis tas li ntawd, cov khoom siv granite tsis xav tau kev txheej tshwj xeeb lossis impregnation, uas ua rau lawv ruaj khov thiab siv nyiaj tsawg dua.

Ntxiv rau qhov ua tau ntev, cov khoom granite kuj muaj kev tiv thaiv zoo thermal shock. Qhov no txhais tau tias lawv tuaj yeem tiv taus qhov hloov pauv sai sai ntawm qhov kub yam tsis tawg lossis tawg. Qhov zoo no yog qhov tseem ceeb tshwj xeeb hauv cov khoom siv semiconductor uas xav tau qhov kub siab kom ua tiav cov tshuaj tiv thaiv tsim nyog thaum lub sijhawm tsim khoom.

Tsis tas li ntawd xwb, cov khoom granite muab kev ruaj khov ntawm qhov ntev hauv qab cov xwm txheej kev ntxhov siab. Qhov kev ruaj khov no yog qhov tseem ceeb hauv kev tsim khoom semiconductor, vim nws ua kom cov khoom siv ua wafer ua haujlwm nrog kev raug thiab qib siab ntawm qhov raug. Qhov tseeb thiab qhov tseeb thaum kawg txiav txim siab qhov zoo ntawm cov khoom semiconductor tiav.

Zuag qhia tag nrho, qhov ruaj khov thiab hnav tsis kam ntawm cov khoom granite hauv cov khoom siv semiconductor ua rau lawv yog qhov kev xaiv zoo rau kev siv hauv cov chaw muaj kev ntxhov siab siab. Lawv muab kev ruaj khov siab, tiv taus thermal shock, thiab tsis nkag mus rau cov tshuaj corrosive. Yog li ntawd, lawv pab tsim cov khoom semiconductor zoo thaum pab txhawb kev ua haujlwm zoo dua hauv cov txheej txheem tsim khoom nrog cov nqi kho qis dua.
