Qhov chaw ua haujlwm hauv cov txheej txheem tsim khoom semiconductor yog qhov tseem ceeb tshaj plaws los xyuas kom meej qhov zoo ntawm cov khoom siv semiconductor raug tsim. Lub hauv paus granite yog ib qho tseem ceeb ntawm cov txheej txheem tsim khoom, vim nws muab qhov chaw ruaj khov thiab muaj zog tiv taus rau cov cuab yeej thiab cov cuab yeej siv hauv cov txheej txheem. Hauv tsab xov xwm no, peb yuav tham txog qhov yuav tsum tau ua ntawm granite hauv paus rau cov txheej txheem tsim khoom siv hluav taws xob thiab yuav ua li cas kom tswj tau qhov chaw ua haujlwm tsim nyog.
Yuav tsum tau Granite Base
Granite bases yog siv nyob rau hauv semiconductor manufacturing txheej txheem li lawv muab ib tug ruaj khov thiab tiaj tus nto rau cov khoom. Cov hauv qab no yog qee qhov yuav tsum tau ua ntawm granite puag:
1. Kev ruaj ntseg - Lub hauv paus granite yuav tsum ruaj khov txaus los tiv thaiv kev vibration thiab txav ntawm cov tshuab thaum lub sijhawm tsim khoom. Txhua yam tsis ruaj khov hauv lub hauv paus tuaj yeem ua rau muaj qhov tsis xws luag hauv cov khoom kawg.
2. Flatness - Qhov saum npoo ntawm lub hauv paus granite yuav tsum tiaj tus los xyuas kom meej qhov chaw thiab txav ntawm cov cuab yeej thiab cov cuab yeej siv hauv kev tsim khoom. Txawm tias ib qho me me sib txawv hauv qhov flatness ntawm qhov chaw tuaj yeem ua rau muaj teeb meem nrog cov khoom zoo.
3. Tsawg thermal expansion coefficient - Lub thermal expansion coefficient ntawm granite puag yuav tsum tsis tshua muaj raws li nws raug kub kub thaum lub sij hawm tsim khoom. Ib qho kev nthuav dav lossis kev cog lus vim qhov kub thiab txias tuaj yeem ua rau muaj kev cuam tshuam ntawm qhov chaw, cuam tshuam rau qhov kawg ntawm cov khoom zoo.
4. Kev ua haujlwm siab - Lub hauv paus granite yuav tsum tau hnav thiab tsim kua muag vim rov siv cov tshuab thiab cov cuab yeej siv. Txhua yam kev puas tsuaj rau lub hauv paus tuaj yeem ua rau muaj qhov tsis xws luag hauv cov khoom kawg.
5. Zoo thermal conductivity - Lub hauv paus granite yuav tsum muaj cov thermal conductivity zoo vim nws pab tswj qhov kub ntawm cov khoom thaum lub sij hawm tsim khoom.
Kev tuav ib puag ncig ua haujlwm
Qhov ib puag ncig ib puag ncig cov txheej txheem tsim khoom yog qhov tseem ceeb los xyuas kom meej cov khoom zoo thiab txo qhov tsis xws luag. Cov hauv qab no yog qee txoj hauv kev los tswj qhov chaw ua haujlwm tsim nyog:
1. Kev tswj qhov kub thiab txias - Qhov kub ntawm qhov chaw tsim khoom yuav tsum tau tswj thiab tswj kom zoo ib yam kom tsis txhob thermal shock rau cov khoom siv thiab cov cuab yeej.
2. Kev tswj cov av noo - Cov theem ntawm cov av noo nyob rau hauv qhov chaw tsim khoom yuav tsum tau tswj kom txo tau qhov kev pheej hmoo ntawm corrosion los yog kev puas tsuaj rau cov khoom siv.
3. Kev huv huv - Kev tswj kom huv ib puag ncig yog qhov tseem ceeb los tiv thaiv kev sib kis thiab txo qhov tsis xws ntawm cov khoom kawg. Qhov chaw tsim khoom yuav tsum tau muab ntxuav tsis tu ncua, thiab cov khoom nchuav lossis cov khib nyiab yuav tsum tau muab tshem tawm tam sim ntawd.
4. Kev tswj kev vibration - kev vibration tuaj yeem ua rau tsis ruaj khov hauv cov khoom siv thiab cov cuab yeej, ua rau muaj qhov tsis xws ntawm cov khoom kawg. Kev tswj thiab txo qis kev vibration theem hauv cheeb tsam tsim khoom yog qhov tseem ceeb.
5. Teeb pom kev zoo - teeb pom kev zoo yog qhov tseem ceeb los xyuas kom meej qhov pom ntawm cov txheej txheem tsim khoom thiab saib xyuas cov teeb meem lossis teeb meem thaum lub sijhawm ua haujlwm.
Hauv kev xaus, lub hauv paus granite yog ib qho tseem ceeb ntawm cov khoom siv semiconductor manufacturing txheej txheem, muab qhov chaw ruaj khov thiab tiaj tus rau cov khoom siv. Kev tuav lub chaw ua haujlwm tsim nyog yog qhov tseem ceeb los xyuas kom meej qhov zoo ntawm cov khoom kawg thiab txo qhov tsis xws luag. Ib puag ncig yuav tsum tau tswj xyuas, huv si, thiab tsis muaj kev vibration kom ntseeg tau tias cov khoom siv thiab cov cuab yeej ua haujlwm tau zoo thaum lub sijhawm tsim khoom.
