Munyika yekugadzira semiconductor, wafer yekugadzira michina inoshandiswa kugadzira akasanganiswa maseketi, microprocessors, memory chips, uye zvimwe zvinhu zvemagetsi.Iyi midziyo inoda chigadziko chakagadzikana uye chakasimba kuti ive nechokwadi chekugadzirisa uye kurongeka.
Iyo granite muchina base ndeimwe yemhando dzakakurumbira dzemabhesi emuchina anoshandiswa muwafer kugadzirisa michina.Sezvinoratidzwa nezita racho, inogadzirwa kubva kugranite, dombo rinongoitika rega rinozivikanwa nokuda kwesimba rayo guru uye kuoma.
Iyo granite muchina base inopa akati wandei mabhenefiti kana ichienzaniswa nemamwe marudzi emabhesi emuchina sesimbi yakakandwa, simbi, kana aluminium.Imwe yemabhenefiti ekutanga ndeye yakanakisa damping zvimiro.Kunyorova (Damping) zvinoreva kugona kwechinhu kutora mavhinga uye kuderedza ruzha.Granite ine yakaderera resonant frequency, izvo zvinoreva kuti inogona kunyorovesa vibrations zviri nani pane zvimwe zvinhu.Nekuda kweizvozvo, iyo wafer yekugadzira michina inogona kushanda nekumhanya kwepamusoro, uye machipisi anogadzirwa akanyanya kunaka uye asingatani kukanganisa.
Imwe mukana weiyo granite muchina base ndeyekudzikama kwayo.Granite ine yakaderera coefficient of thermal kuwedzera, izvo zvinoreva kuti haina kunyanya kuwedzera kana chibvumirano nekushanduka kwekushisa.Ichi chivakwa chinovimbisa kuti wafer yekugadzira michina inochengetedza kwayo chaiyo kunyangwe ichiiswa mukushandurwa kwezvakatipoteredza.
Granite zvakare inoshingirira kupfeka uye kubvaruka uye haiparare zviri nyore.Ichi chivakwa chinoita kuti ive yakanakira kushandiswa munzvimbo dzakaomarara dzemaindasitiri, uko iyo wafer yekugadzira michina inoiswa pasi pemakemikari uye abrasive zvikamu.Granite zvakare iri nyore kuchenesa nekuchengetedza, zvichiita kuti ive sarudzo yakakurumbira yewafer processing equipment.
Mukupedzisa, chigadziko chemuchina wegranite chinhu chakakosha chechero wafer processing equipment.Iyo yakanaka kwazvo yekunyorovesa zvimiro, kugadzikana kwedimensional, uye kuramba kupfeka uye kubvarura kunoita kuti ive sarudzo yakanaka yekugadzira emhando yepamusoro zvinhu zvemagetsi.Nekuenderera mberi kudiwa kwehunyanzvi hwepamberi, kukosha kweiyo granite muchina base kunongokura mune ramangwana.
