Indlela yokusebenzisa i-Granite esetshenziswa emishinini yokucubungula i-wafer?

I-Granite iyitshe lemvelo eliye laba yingxenye ebalulekile yemishini yokucubungula i-wafer ngenxa yezakhiwo zalo ezihlukile. Kulesi sihloko, sizoxoxa ngezici ezibalulekile ze-granite nokuthi isetshenziswa kanjani emishinini yokucubungula i-wafer.

Iyini iGranite?

I-Granite uhlobo lwedwala eliyi-igneous elinesakhiwo sekristalu futhi lakhiwe ngamaminerali ahlukene, kufaka phakathi i-quartz, i-feldspar, ne-mica. Ingenye yamatshe emvelo aqinile futhi ayigugi futhi ayidabuki, okwenza ifaneleke ukusetshenziswa ezindaweni zezimboni. Amandla nokuqina kwe-granite kuyenza ibe yinto efanelekile yezisekelo zomshini kanye nezingxenye.

Ukusebenzisa i-Granite kumishini yokucubungula i-Wafer

Kunezindlela eziningana zokusebenzisa i-granite emishinini yokucubungula i-wafer. Ezinye zezinhlelo zokusebenza ezivame kakhulu zifaka:

Ama-Wafer Chucks

Ama-wafer chucks asetshenziselwa ukubamba ama-wafer e-silicon endaweni yawo phakathi nezigaba ezahlukene zokucubungula ama-wafer. I-Granite iyinto efanelekile yama-wafer chucks ngoba ine-coefficient ephansi yokwanda kokushisa, okusho ukuthi ayithinteki ukushintsha kwezinga lokushisa. Lokhu kuzinza kubalulekile ekugcineni ukunemba okudingekayo ngesikhathi sokucubungula ama-wafer.

Izingxenye Zesakhiwo

I-Granite isetshenziselwa futhi ukwenza izingxenye zesakhiwo, njengezisekelo zomshini, ozimele, namakholomu. Lezi zingxenye kudingeka ziqine futhi ziqine ukuze zimelane nokudlidliza nokucindezeleka okwenzeka ngesikhathi sokucubungula i-wafer. I-Granite inikeza ukuzinza okudingekayo, iqinisekisa ukuthi imishini igcina ukunemba kwayo nokunemba kwayo.

Amaphedi okupholisha

Ama-pads okupholisha asetshenziselwa ukupholisha nokushelela ubuso be-silicon wafers. I-Granite isetshenziselwa ukwenza la ma-pads ngoba anomumo ofanayo wobuso ohlinzeka ngemiphumela efanayo. Itshe futhi alikwazi ukuguguleka nokuklebhuka, okusho ukuthi ama-pads angasetshenziswa ngokuphindaphindiwe ngaphandle kokuguguleka ngokushesha.

Izinzuzo Zokusebenzisa I-Granite Emishinini Yokucubungula I-Wafer

Kunezinzuzo eziningana zokusebenzisa i-granite emishinini yokucubungula i-wafer. Ezinye zalezi zinzuzo zifaka:

Ukuzinza

I-Granite ine-coefficient ephansi yokwanda kokushisa, okusho ukuthi ayithinteki izinguquko zokushisa. Lokhu kuzinza kuqinisekisa ukuthi imishini yokucubungula i-wafer ihlala inembile futhi inembile, ngisho nalapho kwenzeka ukushintshashintsha kwezinga lokushisa.

Ukuqina

I-Granite iyinto eqinile futhi eqinile engamelana nokuguguleka. Ihlinzeka ngokuqina okudingekayo kwezisekelo zomshini kanye nezingxenye, iqinisekisa ukuthi umshini uhlala isikhathi eside futhi unokwethenjelwa.

Ukunemba

Ukuthungwa okufanayo kobuso be-granite kuqinisekisa ukuthi imishini igcina ukunemba kwayo nokunemba kwayo. Lokhu kubalulekile phakathi nezigaba zokucubungula i-wafer lapho ngisho nokuphambuka okuncane kungabangela ukwenqatshwa kwe-wafer.

Isiphetho

Ekuphetheni, ukusetshenziswa kwe-granite emishinini yokucubungula i-wafer kuyisici esibalulekile senqubo yokukhiqiza i-semiconductor. Izakhiwo zayo ezihlukile zokuzinza, ukuqina, kanye nokunemba kwenza kube yinto efanelekile yokusetshenziswa ezisekelweni zomshini, izingxenye, kanye nama-polish pad. Ukusetshenziswa kwe-granite emishinini yokucubungula i-wafer kuthuthukise ikhwalithi, ukunemba, kanye nokuthembeka kwemboni ye-semiconductor, okuqinisekisa ukuthi izinto zobuchwepheshe zakamuva kanye nobuchwepheshe kukhiqizwa ngezindinganiso zekhwalithi ephezulu.
