Kodi mbale yopukutira ya alumina ceramic wafer yoyera kwambiri ndi chiyani?

Chifukwa cha kukula kwachangu kwa makampani opanga zinthu za semiconductor, kukula kwa makampaniwa kwakula mofulumira, ndipo zida zopangira zinthu za semiconductor zapitiliza kusintha kukhala zolondola komanso zovuta. Chifukwa chakuti zinthu za ceramic zili ndi ubwino wa kuuma kwambiri, modulus yolimba kwambiri, kukana kukalamba kwambiri, kutchinjiriza kwambiri, kukana dzimbiri, kukulitsa pang'ono, ndi zina zotero, zitha kugwiritsidwa ntchito ngati zigawo za makina opukutira a silicon, zida zoyeretsera kutentha za epitaxial/oxidation/diffusion, makina a lithography, zida zoyikamo, zida zoyeretsera za semiconductor, makina oyika ma ion ndi zida zina, kotero kafukufuku ndi chitukuko ndi kupanga zida zolondola za ceramic zimakhudza mwachindunji chitukuko cha makampani opanga zinthu za semiconductor. Zofunikira zaukadaulo pakukonza kwake zikukwera kwambiri.

Alumina yoyera kwambiri, 99.7% -99.9% alumina.
Mphamvu yamakina yapamwamba, kukana kuvala kwambiri, kutchinjiriza magetsi kwambiri, kukhazikika kwa mankhwala ambiri, kukana kutentha bwino komanso kukana dzimbiri. Pakadali pano, kugwiritsa ntchito ceramic grinding disc semiconductor silicon wafer ndiyo njira yabwino kwambiri komanso yapamwamba kwambiri yopera. Njira yopera mbali zonse ziwiri imagwiritsidwa ntchito popera silicon wafer yodulidwa, ndipo ubwino wa grinding wafer umawonjezeka mwa kukonza njira yopera (zinthu zama disc, madzi opera, kupanikizika kwa grinding ndi liwiro lopera, ndi zina zotero). Makamaka, kugwiritsa ntchito mbale za ceramic m'malo mwa mbale zachitsulo zoponyedwa, kuti mupewe kugaya pamwamba pa wafer chifukwa cha zipsera kapena kuipitsa, kuchepetsa kuyambika kwa ayoni achitsulo, kungachepetse kukonza kwa silicon pambuyo pake, kufupikitsa nthawi yopangira (dzimbiri), kusintha magwiridwe antchito, ndikuchepetsa kutayika kwa silicon processing, ndikuwonjezera kwambiri kugwiritsa ntchito silicon.

Mbale yopukutira ya alumina wafer yokwera kwambiriimagwiritsidwa ntchito mu semiconductor, petroleum, chemical, photovoltaic, liquid crystal ndi mafakitale ena, monga zida zamakaniko, zida zamagetsi, microwave induction disk, zipangizo zotenthetsera ndi zina, zida zamakaniko, zida zotsukira, zida zopangira ma crystal amadzimadzi ndi zina. Zida zazikulu za alumina ceramics ndi zazikulu komanso zoyera kwambiri zimakhala ndi phindu lofunika kwambiri mumakampani a safiro ndi mafakitale a semiconductor chips. Ndi chithandizo chofunikira komanso chogwiritsidwa ntchito popukuta makina a chemical mechanical (CMP) a safiro ndi ma silicon wafers a semiconductor. Zida zazikulu za alumina ceramics ndi zazikulu komanso zoyera kwambiri zingagwiritsidwenso ntchito ngati gawo la alumina la LCD.
