Granite ndi chinthu chodziwika bwino pamakampani opanga zinthu zophika chifukwa cha mawonekedwe ake apadera komanso kulimba kwake.Ndi mwala wachilengedwe womwe umakumbidwa kuchokera ku miyala padziko lonse lapansi ndipo wakhala ukugwiritsidwa ntchito kwazaka zambiri pazomanga zosiyanasiyana, kuphatikiza kupanga zida za semiconductor.M'nkhaniyi, tikambirana zamtengo wapatali wa granite ndi ntchito zake zosiyanasiyana pazida zopangira zopyapyala.
Makhalidwe a Granite
Granite ndi mwala woyaka moto womwe umapangidwa ndi mica, feldspar, ndi quartz.Imadziwika ndi mphamvu zake zapadera, kuuma kwake, komanso kulimba kwake, zomwe zimapangitsa kuti ikhale yabwino kwambiri pamapulogalamu omwe amafunikira kulondola kwambiri komanso kulondola.Granite ili ndi coefficient yotsika ya kukula kwa kutentha, zomwe zikutanthauza kuti sizimakula kapena kugwirizanitsa chifukwa cha kusintha kwa kutentha, zomwe zimapangitsa kuti zikhale zokhazikika kwambiri.Kuonjezera apo, granite imagonjetsedwa ndi dzimbiri ndi mankhwala, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito m'madera ovuta.
Kugwiritsa Ntchito Granite mu Wafer Processing Equipment
Granite ndi chinthu chomwe chimagwiritsidwa ntchito kwambiri pamakampani opanga zopindika chifukwa cha kuphatikiza kwake kwapadera.Izi ndi zina mwazogwiritsira ntchito granite pazida zopangira zopindika:
1. Zida za Metrology
Granite amagwiritsidwa ntchito kwambiri popanga zida za metrology, monga makina oyezera a coordinate (CMMs) ndi makina oyezera maso.Zidazi zimafuna malo okhazikika omwe amatha kukana kugwedezeka ndi kutentha.Kuuma kwakukulu komanso kutsika kwamafuta pang'ono kwa granite kumapangitsa kuti ikhale chinthu choyenera kugwiritsa ntchito.
2. Wafer Chucks
Wafer chucks amagwiritsidwa ntchito kunyamula zowotcha panthawi yopanga.Ma chucks awa amafunikira malo osalala komanso okhazikika kuti chiwombankhanga chisagwedezeke kapena kupindika.Granite imapereka malo athyathyathya omwe amakhala okhazikika komanso osasunthika, kupangitsa kuti ikhale chinthu chabwino kwambiri chopangira ma chucks.
3. Zida za Chemical Mechanical polishing (CMP).
Zida za CMP zimagwiritsidwa ntchito kupukuta zowotchera panthawi yopanga.Zida izi zimafuna nsanja yokhazikika yomwe imatha kukana kugwedezeka ndi kutentha.Kuuma kwabwino kwambiri komanso kutsika kwamafuta pang'ono kwa granite kumapangitsa kukhala chinthu choyenera pazida za CMP.
4. Wafer Inspection Zida
Chida chowunikira chawafer chimagwiritsidwa ntchito kuyang'ana zowotcha zowongoka ngati zili ndi zolakwika ndi zolakwika.Zida zimenezi zimafuna malo okhazikika komanso ophwanyika kuti atsimikizire miyeso yolondola.Granite imapereka malo okhazikika komanso athyathyathya omwe amalimbana ndi kugwedezeka, ndikupangitsa kuti ikhale chinthu chabwino kwambiri pazida zowunikira.
Mapeto
Pomaliza, granite ndi chinthu chomwe chimagwiritsidwa ntchito kwambiri pamakampani opanga zopangira zingwe chifukwa cha mawonekedwe ake apadera komanso kulimba kwake.Amagwiritsidwa ntchito kwambiri popanga zida za metrology, ma wafer chucks, zida za CMP, ndi zida zowunikira ma wafer.Kuphatikizika kwapadera kwa katundu kumapangitsa kukhala chinthu choyenera kwa mapulogalamu omwe amafunikira kulondola kwambiri komanso kulondola.Ndi maubwino ake ambiri, granite imakhalabe chisankho chodziwika bwino pazida zopangira zopindika, ndipo kugwiritsidwa ntchito kwake kukuyembekezeka kupitiliza kukula mtsogolo.
