Zithini izinto zegranite zeWafer Processing Equipment?

Izixhobo zokucubungula iiwafer zisetyenziswa kwinkqubo yokuvelisa ii-semiconductor ukuguqula iiwafer zesilicon zibe ziisekethe ezidibeneyo. Ziquka uluhlu lwezixhobo ezintsonkothileyo kunye nezixhobo ezisetyenziselwa ukwenza imisebenzi emininzi ebalulekileyo, kubandakanya ukucoca iiwafer, ukukrola, ukubeka, kunye nokuvavanya.

Izinto zegranite ziyinxalenye ebalulekileyo yezixhobo zokucubungula i-wafer. Ezi zinto zenziwe ngegranite yendalo, elilitye eliyi-igneous elenziwe yi-quartz, i-feldspar, kunye ne-mica. Igranite ifanelekile ekusetyenzweni kwe-wafer ngenxa yeempawu zayo ezibalaseleyo zoomatshini, ubushushu, kunye neekhemikhali.

Iimpawu zoomatshini:

I-granite yinto eqinileyo nexineneyo ekwaziyo ukumelana nokuguguleka nokuguquka. Inomlinganiselo ophezulu wamandla nobunzima, oko kuthetha ukuba inokumelana nemithwalo enzima ngaphandle kokuqhekeka okanye ukuqhekeka. Le propati yenza ukuba ibe lukhetho oluhle kakhulu kwiindawo ezichanekileyo ezifuna ukuchaneka okugqithisileyo.

Iipropati zobushushu:

I-granite inomlinganiselo ophantsi wokwanda kobushushu, nto leyo ethetha ukuba ayikhuli okanye ayinciphisi kakhulu xa ichaphazeleka kutshintsho lobushushu. Le propati iyenza ibe yinto efanelekileyo yokusetyenziswa kwizixhobo zokucubungula i-wafer, apho ulawulo lobushushu lubaluleke kakhulu.

Iimpawu zekhemikhali:

I-granite iyakwazi ukumelana nokugqwala kweekhemikhali, nto leyo eyenza ukuba ilungele ukusetyenziswa kwiindawo ezinobungozi zeekhemikhali. Ayisebenzi kwiiasidi ezininzi, iziseko, okanye izinyibilikisi, nto leyo eyenza ukuba ibe lukhetho oluhle kakhulu kwinkqubo yokugqwala iikhemikhali esetyenziswa ekucutshungulweni kwe-wafer.

Izixhobo zegranite ziyinxalenye ebalulekileyo yezixhobo zokucubungula i-wafer. Zisetyenziswa kwiinkqubo ezininzi ezibalulekileyo, kubandakanya ukucoca i-wafer, ukukrola, kunye nokubeka i-deposition. Zibonelela ngeqonga elizinzileyo nelihlala ixesha elide lezixhobo, eliqinisekisa iziphumo ezichanekileyo nezithembekileyo.

Ngamafutshane, izixhobo zokucubungula i-wafer zibalulekile ekwenzeni iisekethe ezidibeneyo, kwaye izinto zegranite zidlala indima ebalulekileyo ekusebenzeni kwazo. Ezi zinto zenziwe ngegranite yendalo, ebonelela ngeempawu ezibalaseleyo zoomatshini, ubushushu, kunye neekhemikhali ezifanelekileyo ekucutshungulweni kwe-wafer. Izinto zegranite zibonelela ngeqonga elizinzileyo nelihlala ixesha elide lezixhobo, eliqinisekisa iziphumo ezichanekileyo nezithembekileyo.
