Cov kev xaiv rau cov khoom siv granite hauv cov khoom siv semiconductor? Dab tsi yog qhov zoo thiab tsis zoo ntawm cov kev xaiv lwm yam piv rau granite?

Granite tau siv cov khoom siv uas siv tau nyob hauv cov khoom lag luam semiconduct rau nws cov khoom siv neeg kho kom zoo nkauj, thiab qis coefficient ntawm thermal expansion. Txawm li cas los xij, nrog cov kev thov puas tau muaj dua rau cov khoom siv siab dua thiab lwm cov khoom siv tau tshwm sim raws li cov khoom siv hluav taws xob sib xyaw. Hauv tsab xov xwm no, peb yuav tshawb qee cov ntaub ntawv xaiv rau cov khoom siv granite thiab sib piv lawv cov kev sib piv thiab qhov tsis zoo.

Lwm cov ntaub ntawv rau cov av granite

1. Cov ntaub ntawv-iav-tej hub

Iav-Khoom siv cov khoom siv, xws li Zerodur thiab cov nqi zog, tau nce ntxiv hauv kev lag luam semiconduction rau qhov lawv muaj kev nthuav dav tsawg, uas ze rau ntawm silicon. Yog li, cov ntaub ntawv no tuaj yeem muab cov thermal stability thiab txhim kho precision hauv cov txheej txheem fabreatteror. Zerodur, tshwj xeeb, muaj qib siab homogeneity thiab ruaj khov, ua rau nws tsim nyog rau kev tsim khoom ntawm cov khoom siv liithograph.

Qhov Zoo:

- Tsawg coefficient ntawm thermal expansion
- siab precision thiab ruaj khov
- Haum rau cov ntawv thov kub siab

Qhov tsis zoo:

- Tus nqi siab dua piv rau Granite
- Tus raug nplawm, tej zaum yuav ua rau cov kev sib tw nrog machining thiab tuav

2. Ceramics

Cov ntaub ntawv muaj tej hub, xws li txhuas oxide (al2o3), siic carbide (Si3N4), muaj kev nthuav dav kub, thiab tsis muaj cua sov cov kev nthuav dav. Cov khoom no ua rau ceramics zoo tagnrho rau cov cuab yeej siv semiconduct cov khoom siv uas yuav tsum muaj siab thermal stability thiab precision, xws li wafer stages thiab chucks.

Qhov Zoo:

- siab thermal ruaj khov thiab lub zog
- Tsawg thermal nthuav kev nthuav dav
- High hnav tsis kam thiab tshuaj inertness

Qhov tsis zoo:

- tuaj yeem tawg thiab nquag mus tawg, tshwj xeeb tshaj yog thaum lub tshuab machining thiab tuav
- Machining thiab Polishing ntawm Ceramics tuaj yeem nyuaj thiab siv sijhawm

3. Hlau

Cov khoom siv hlau, xws li cov hlau stainless thiab titanium, tau siv rau qee cov cuab yeej siv semiconduct cov khoom uas lawv zoo heev machinability thiab siab zog. Lawv feem ntau siv nyob rau hauv cov ntawv thov uas siab thermal ruaj khov tsis tas yuav tsum tau, xws li Chamber Qhov, txuas ntxiv, thiab cov zaub mov.

Qhov Zoo:

- Zoo machinability thiab weldability
- Muaj lub zog siab thiab ductility
- Tus nqi qis piv rau qee cov khoom siv

Qhov tsis zoo:

- siab thermal expansion coefficient
- Tsis haum rau cov ntawv thov kub siab vim yog cov teeb meem hluav taws xob
- Raug rau kev xeb thiab paug

Xaus:

Hauv cov ntsiab lus, thaum Granite tau muaj kev xaiv nrov rau cov cuab yeej cuab tam tau, lwm cov khoom siv tau tshwm sim, txhua tus nrog cov txiaj ntsig zoo thiab qhov tsis zoo. Iav-Khoom Siv Cov Khoom Siv yog muaj tseeb heev thiab ruaj khov tab sis tuaj yeem tawg tau. Ceramics muaj zog thiab muaj cov khoom ruaj khov ua hluav taws xob tab sis kuj tseem tuaj yeem muaj nkig, ua rau lawv nyuaj rau kev tsim khoom. Cov hlau yog pheej yig, machinctable, thiab ducast, tab sis lawv muaj cov coefficient ntawm thermal expansion thiab muaj kev cuam tshuam rau kev xeb thiab paug. Thaum xaiv cov ntaub ntawv rau cov cuab yeej ua semiconductor, nws yog qhov tseem ceeb los xav txog cov kev cai tshwj xeeb ntawm daim ntawv thov thiab xaiv cov ntaub ntawv uas tshuav nqi, thiab ntseeg tau.
