Ntiv nplhaib Graphite Coated Tantalum Carbide uas muaj qhov nqus tau
Cov graphite coated nrog tantalum carbide (TaC) uas muaj qhov porousyog ib yam khoom tseem ceeb uas tsim tshwj xeeb rau qhov kub thiab txias, qhov chaw muaj zog heev ntawm kev tsim khoom semiconductor. Nws cov substrate yog high-purity isostatic graphite, coated nrog ib txheej tantalum carbide uas siv cov tshuaj vapor deposition (CVD). TaC muaj qhov nyuaj heev (9-10 ntawm Mohs scale) thiab qhov chaw yaj ntawm 3880 ° C. Ua ke nrog graphite qhov kev ruaj khov thermal zoo heev thiab cov khoom sib dua, cov khoom no ua ke muaj zog kub thiab tiv taus tshuaj lom neeg thiab thermal shock, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov khoom siv semiconductor ua haujlwm hauv qab cov xwm txheej hnyav.
Cov txiaj ntsig ntawm Tantalum Carbide Graphite uas muaj qhov ntxeem tau:
1. Kev Tiv Thaiv Corrosion Siab Tshaj Plaws
-TaC yog tshuaj inert, zoo tiv taus xeb los ntawm halogens xws li fluorine thiab chlorine, ua rau lub neej khoom siv ntev dua.
-Cov qauv porous ua rau thaj chaw ntawm cov txheej txheej ntau ntxiv, tsim kom muaj kev tiv thaiv zoo dua thiab txo qhov kev pheej hmoo ntawm cov khoom me me.
2. Kev Ruaj Ntseg Kub Siab Zoo heev
-Nrog rau qhov chaw yaj ze li ntawm 4000 ° C, nws tuaj yeem ua haujlwm rau lub sijhawm ntev hauv lub tshuab nqus tsev lossis inert atmospheres tshaj 2500 ° C.
-Qhov coefficient ntawm thermal expansion ntawm lub txheej yog sib phim zoo rau ntawm graphite, tiv thaiv kev tawg thiab delamination los ntawm thermal cycling.
3. Kev Ntshiab Siab thiab Kev Ua Phem Tsawg
-Siv cov khoom siv raw thiab cov txheej txheem semiconductor-qib, cov ntsiab lus hlau tsis huv yog qis heev, txo qhov kev pheej hmoo ntawm kev ua qias tuaj ntawm wafer.
-Qhov nto yog ntom thiab ruaj khov, txo cov khoom me me thiab ua tau raws li cov qauv huv si.
4. Kev Tsim Qauv Tshwj Xeeb
Cov duab sib txawv tuaj yeem tsim tau raws li cov neeg siv khoom kos duab, thiab porosity thiab txheej thickness tuaj yeem tswj tau kom ua tiav cov roj ntws zoo tshaj plaws thiab thermal conductivity.
5. Lub Neej Ntev Thiab Tus Nqi Txij Nkawm Tsawg
Qhov kev tiv thaiv xeb thiab hnav tsis kam ntawm cov txheej txheem TaC uas muaj qhov ntxeem tau ua rau lub neej ntawm cov khoom siv ntev dua 3-5 npaug piv rau cov graphite ib txwm muaj, txo cov zaus hloov pauv thiab cov nqi txij nkawm.
