I-Granite idwala elenzeka ngokwemvelo elisetshenziswe isikhathi eside kumishini yokucubungula i-wafer.Iyaziwa ngezindawo zayo ezinhle kakhulu zokuba nokwanda okushisayo okuphansi, ukuqina okuphezulu nokuzinza okuhle.Kodwa-ke, njengazo zonke izinto zokwakha, i-granite inesethi yayo yokukhubazeka engathinta ikhwalithi yemishini yokucubungula i-wafer.
Esinye seziphambeko ezinkulu ze-granite ukuthambekela kwayo ukuqhekeka noma ukuphuka.Lokhu kungenxa yokuba khona kwama-microcracks okungenzeka ngesikhathi sokubunjwa kwedwala.Uma lezi microcracks zingabonwa futhi ziphathwe kahle, zingasakazeka futhi ziholele ekuhlulekeni kwemishini.Ukuvimbela lokhu ukuthi kungenzeki, abakhiqizi bemishini yokucubungula kudingeka basebenzise i-granite yekhwalithi ephezulu eselashwe futhi yahlolwa ukuze kuqinisekiswe ukuthi ayinawo ama-microcracks.
Esinye isici se-granite ukuthi ikwazi ukugqwala.Uma okokusebenza kwegwadle kuhlangana nezindawo ezonakalisayo, kungase kuqale ukuwohloka ngokuhamba kwesikhathi.Lokhu kungaholela ekutheni imishini yonakale noma ingasebenzi kahle.Ukuvimbela lokhu, abakhiqizi kufanele baqinisekise ukuthi igwadle elisetshenziswa ezintweni zabo liphathwa ngendlela efanele futhi limbozwe ukuze kuvinjelwe noma yikuphi ukugqwala kungenzeki.
I-Granite nayo ijwayele ukungqubuzana ngokuhamba kwesikhathi ngenxa yezakhiwo zayo ezishisayo.Lokhu kungenxa yokuthi i-granite ine-coefficient ephansi kakhulu yokunwetshwa kokushisa, okusho ukuthi ayikhuli noma inciphe kakhulu uma ingaphansi kwezinguquko kuzinga lokushisa.Kodwa-ke, ngisho nenani elincane lokunwetshwa noma ukufinyela kungabangela ukungqubuzana kwemishini ngokuhamba kwesikhathi.Kubalulekile ukuthi umenzi wezinto zokusebenza acabangele izakhiwo ezishisayo zegwadle lapho eklama okokusebenza kwawo ukuze avimbele lokhu kungenzeki.
Okokugcina, ubume begwadle bungabangela izinkinga ngokungcola.Uma i-granite ingavalwanga kahle, ingakwazi ukumunca ukungcola okungathinta ikhwalithi ye-wafer.Lokhu kungaholela ekunciphiseni isikhathi esibizayo kanye nokulahlekelwa ukukhiqizwa.Ukuvimbela lokhu, abakhiqizi badinga ukuvala kahle igwadle ukuvimbela noma yikuphi ukungcola ukuthi kungamuncwa.
Sengiphetha, i-granite iyinto enhle kakhulu yokusetshenziswa kumishini yokucubungula ama-wafer.Kodwa-ke, kubalulekile ukuqaphela ukukhubazeka kwayo futhi uthathe izinyathelo ezidingekayo ukuze uzivimbele ukuthi zingenzeki.Ngokunakekelwa nokugcinwa okufanele, imishini ye-granite ingaqhubeka nokusebenza iminyaka eminingi, ihlinzeka ngamawafa ekhwalithi ephezulu embonini ye-semiconductor.
