Yintoni iGranite esetyenziswa kwizixhobo zokucubungula i-wafer?

I-Granite yinto edumileyo kwishishini lokucubungula ii-wafer ngenxa yeempawu zayo ezibalaseleyo zoomatshini kunye nokuqina kwayo. Lilitye lendalo elimbiwa kwiingcango kwihlabathi liphela kwaye lisetyenziswe kangangeenkulungwane kwiinjongo ezahlukeneyo zokwakha, kubandakanya ukwenziwa kwezixhobo ze-semiconductor. Kweli nqaku, siza kuxoxa ngeempawu ze-granite kunye nokusetyenziswa kwayo okuhlukeneyo kwizixhobo zokucubungula ii-wafer.

Iipropati zeGranite

I-Granite lilitye eliyi-igneous elenziwe yi-mica, i-feldspar, kunye ne-quartz. Yaziwa ngamandla ayo angaqhelekanga, ubulukhuni, kunye nokuqina, okwenza ukuba ibe yinto efanelekileyo yokusetyenziswa efuna ukuchaneka okuphezulu kunye nokuchaneka. I-Granite ine-coefficient ephantsi yokwandiswa kobushushu, oko kuthetha ukuba ayikhuli okanye ayinciphi ngenxa yotshintsho lobushushu, nto leyo eyenza ukuba izinze kakhulu. Ukongeza, i-granite iyamelana nokugqwala kunye neekhemikhali, nto leyo eyenza ukuba ibe yinto efanelekileyo yokusetyenziswa kwiindawo ezinzima.

Ukusetyenziswa kweGranite kwiZixhobo zokuSebenza ngeWafer

I-Granite yinto esetyenziswa kakhulu kwishishini lokucubungula ii-wafer ngenxa yokudibanisa kwayo okuhlukileyo kweempawu. Nazi ezinye zeendlela ezisetyenziswa ngayo i-granite kwizixhobo zokucubungula ii-wafer:

1. Izixhobo zeMetrology

I-granite isetyenziswa kakhulu ekwenzeni izixhobo ze-metrology, ezifana noomatshini bokulinganisa abalungelelanisiweyo (ii-CMM) kunye neenkqubo zokulinganisa ezibonakalayo. Ezi zixhobo zifuna iindawo ezizinzileyo ezinokumelana nokungcangcazela nobushushu. Ukuqina okuphezulu kunye nokwanda okuphantsi kobushushu be-granite kwenza ukuba ibe yinto efanelekileyo yokusetyenziswa kwezi zinto.

2. IiWafer Chucks

Ii-wafer chucks zisetyenziselwa ukubamba ii-wafers ngexesha lenkqubo yokwenziwa. Ezi chucks zifuna umphezulu othe tyaba nozinzileyo ukuthintela i-wafer ukuba ingagobi okanye igobe. I-Granite inika umphezulu othe tyaba ozinzileyo kakhulu kwaye omelana nokugoba, nto leyo eyenza ukuba ibe yinto efanelekileyo kwii-wafer chucks.

3. Izixhobo zokuCoca ngoomatshini beKhemikhali (CMP)

Izixhobo ze-CMP zisetyenziselwa ukupolisha ii-wafers ngexesha lenkqubo yokwenziwa. Ezi zixhobo zifuna iqonga elizinzileyo elinokumelana nokungcangcazela nobushushu. Ukuqina okugqwesileyo kunye nokwanda okuphantsi kobushushu begranite kwenza ukuba ibe yinto efanelekileyo kwizixhobo ze-CMP.

4. Izixhobo zokuhlola iWafer

Izixhobo zokuhlola iiwafer zisetyenziselwa ukuhlola iiwafers ukuze zibone iziphene kunye neziphene. Ezi zixhobo zifuna umphezulu ozinzileyo nothe tyaba ukuqinisekisa umlinganiselo ochanekileyo. Igranite inika umphezulu ozinzileyo nothe tyaba omelana nokugoba, nto leyo eyenza ukuba ibe yinto efanelekileyo kwizixhobo zokuhlola iiwafers.

Isiphelo

Ukuqukumbela, igranite sisixhobo esisetyenziswa kakhulu kwishishini lokucubungula i-wafer ngenxa yeempawu zayo ezibalaseleyo zoomatshini kunye nokuqina kwayo. Isetyenziswa kakhulu ekuveliseni izixhobo ze-metrology, ii-wafer chucks, izixhobo ze-CMP, kunye nezixhobo zokuhlola i-wafer. Indibaniselwano eyahlukileyo yeempawu yenza ukuba ibe yinto efanelekileyo kwizicelo ezifuna ukuchaneka okuphezulu kunye nokuchaneka. Ngenxa yeenzuzo zayo ezininzi, igranite ihlala ilukhetho oludumileyo lwezixhobo zokucubungula i-wafer, kwaye ukusetyenziswa kwayo kusenokwenzeka ukuba kuqhubeke nokukhula kwixesha elizayo.
