Qhov zoo thiab tsis zoo ntawm wafer ua khoom siv granite

Muaj cov khoom siv ua tau zoo yog siv los ua cov khoom siv microelectronics thiab semiconductor devices. Hom khoom siv no muaj ntau lub ntsiab lus, suav nrog cov khoom siv granite. Granite yog cov khoom siv ntau yam uas tau siv nyob rau hauv kev tsim cov semiconductor ua khoom siv vim nws cov tshuab ruaj khov, thiab seem ruaj khov, thiab seem ruaj khov. Kab lus no yuav tham txog qhov zoo thiab qhov tsis zoo ntawm kev siv cov khoom siv granite hauv kev nyab xeeb ua khoom siv.

Qhov Zoo:

1. Mechanical stability: cov cheebtsam granite yog qhov ruaj khov, tshwj xeeb tshaj yog thaum muaj kub. Qhov no ua rau lawv zoo tagnrho rau kev siv kev tiv thaiv cov cuab yeej siv, uas ua haujlwm ntawm qhov kub. Cov khoom siv granite tuaj yeem tiv thaiv cov nra hnyav, vibrations, thiab thermal poob siab yam tsis muaj deformation, uas ua kom cov ntsuas siab thiab qhov tseeb.

2. Tshuaj Tiv Thaiv: Granite yog tiv taus ntau cov tshuaj feem ntau siv nyob rau hauv kev tiv thaiv zoo, suav nrog cov kua qaub, hauv paus, thiab cov kuab tshuaj. Qhov no ua rau muaj kev nyab tawm cov khoom siv los ua cov neeg sawv cev corrosive yam tsis muaj kev ua kom cov khoom siv hluav taws xob.

3. Qhov ruaj khov stability: granite Cheebtsam muaj qhov siab ruaj khov, uas txhais tau tias lawv tswj lawv cov duab thiab loj txawm tias huab cua thiab av noo. Qhov no yog qhov tseem ceeb heev rau kev sib tw ua khoom siv, uas yuav tsum muaj kev ua kom muaj qhov tseeb ntawm kev ua.

4. Tsawg coefficient ntawm thermal expansion: granite muaj qhov tsis tshua muaj kev nthuav dav ntawm thermal expandion, uas txhais tau tias nws tsis nthuav dav thaum raug rau kev kub ntxhov. Qhov no ua rau nws zoo meej rau cov khoom siv kev nyab xeeb uas tau raug rau qhov kub.

5. Kev siv lub neej ntev: Granite yog cov khoom siv ruaj thiab muaj peev xwm kav ntev rau ntau xyoo, txawm nyob hauv ib puag ncig hnyav. Qhov no txo ​​cov nqi ntawm kev saib xyuas thiab hloov, ua rau cov tuam txhab tsim cov khoom siv zoo ntawm cov nqi qis.

Qhov tsis zoo:

1. Tus nqi siab: Cov khoom siv granite yog kim dua lwm cov ntaub ntawv siv hauv kev nyab xeeb cov cuab yeej siv, xws li hlau lossis txhuas. Tus nqi siab ntawm granite nce tag nrho cov nqi zog ntawm wafer ua cov cuab yeej siv, ua rau nws tsis tuaj yeem siv tau rau cov lag luam me thiab pib.

2. Hnyav hnyav: Granite yog cov khoom siv ntom ntom, thiab nws cov khoom siv tau hnyav dua li lwm cov ntaub ntawv siv hauv kev sib xyaw ua ke cov khoom siv. Qhov no ua rau cov khoom siv thiab nyuaj txav.

3. Qhov nyuaj los kho: granite Cheebtsam yog qhov nyuaj los kho, thiab hloov hluav taws xob feem ntau tsuas yog kev xaiv thaum lawv raug puas. Qhov no ntxiv cov nqi ntxiv rau kev saib xyuas thiab tuaj yeem tsim khoom siv sijhawm ntev.

4. Brittle: Nws yuav tsum tau ua tib zoo saib thiab kev kho kom tsis txhob muaj kev puas tsuaj uas tej zaum yuav daws qhov tsis muaj qhov ntawm cov khoom siv.

Hauv kev xaus, qhov zoo ntawm kev siv cov khoom siv granite nyob rau hauv wafer ua cov cuab yeej ua ntej qhov tsis zoo. Txawm hais tias muaj qee qhov teeb meem, cov tshuab ruaj khov, tshuaj lom neeg tiv thaiv, thiab qhov chaw ruaj khov ntawm kev tsim cov khoom siv zoo thiab cov khoom siv hluav taws xob zoo. Los ntawm kev nqis peev hauv granite, cov tuam ntxhab tuaj yeem ua tiav kev ua tau zoo dua, kev raug, thiab ntev hauv lawv cov khoom siv wafefration.
