Iipadi zokupolisha zidlala indima ebalulekileyo njengesixhobo somatshini wokuchaneka kwicandelo lesayensi yezinto kunye nobunjineli bomphezulu. Umsebenzi wazo kukupolisha umphezulu wezinto ngeendlela zomzimba okanye zeekhemikhali ukuze kufezekiswe ukugqitywa okufunekayo kunye neempawu zomphezulu. Ngokuxhomekeke kwiimfuno zesicelo, iidiski zokupolisha ziyafumaneka kwizinto ezahlukeneyo, ezifana nedayimani, i-alumina, i-silicon carbide, njl.njl., nganye kuzo ineempawu zayo zokusila ezizodwa kunye nobubanzi bokusetyenziswa.
Kwicandelo lokwenziwa kwee-semiconductor, ii-wafers ezipholisiweyo zibaluleke kakhulu, ngakumbi kwinkqubo ye-chemical mechanical polishing (CMP), esetyenziselwa ukufezekisa ukuthamba okuphezulu komphezulu we-wafer. Itekhnoloji ye-CMP idibanisa ukugaya ngoomatshini kunye nokugrumba ngamakhemikhali, isombulula ngempumelelo ukungalungi kwe-micro-geometry ye-wafer, ngaloo ndlela iqinisekisa ukusebenza kunye nokuthembeka kwezinto ze-microelectronic.
Kwicandelo lokucubungula isinyithi, ii-polishing pads zisetyenziselwa ukususa iileya ezingcolisiweyo kunye nongcoliseko kumphezulu wezinto zokusebenza kunye nokuphucula ukugqitywa komphezulu, ngaloo ndlela kuphucula ukubonakala nokusebenza kwezinto. Umzekelo, kumashishini eenqwelo-moya kunye neemoto, apho unyango lomphezulu wezixhobo lufuna kakhulu, ukupolisha kunokuphucula kakhulu ukumelana nokugqwala kunye nobomi bokudinwa kweemveliso.
Kwizinto ezahlukeneyo kunye neemfuno zokucubungula, iiparameter ezinje ngobukhulu bengqolowa, ubulukhuni kunye nokuma kwediski yokupolisha kufuneka zenziwe ngononophelo. Ukukhethwa kobukhulu bengqolowa kuchaphazela ngokuthe ngqo uburhabaxa bomphezulu, ngelixa ubulukhuni bumisela izinga lokususwa kwenkqubo yokupolisha kunye nokuqina kwesixhobo. Ukongeza, uxinzelelo, isantya kunye neemeko zendalo zenkqubo yokupolisha kufuneka zilawulwe ngokungqongqo ukuqinisekisa ukuba umgangatho womphezulu ofunekayo uyafezekiswa.
Inkampani iChemshun Ceramics ngumvelisi weeseramikhi zoshishino oqeqeshiweyo,Iidiski zokuPolisha zeWafer zeAlumina ezingama-99.7%ingafumaneka. Wamkelekile ukubuza.
