Imboni ye-semiconductor ivamise ukubona ithemu lezinto eziqondiwe, ezingahlukaniswa zibe izinto eziyisicwecwana kanye nezinto zokupakisha.Izinto zokupakisha zinezithiyo zobuchwepheshe eziphansi uma kuqhathaniswa nezinto zokwakha eziyisicwecwana.Inqubo yokukhiqiza ama-wafers ikakhulukazi ihilela izinhlobo eziyisi-7 zezinto zokwakha ze-semiconductor namakhemikhali, okuhlanganisa uhlobo olulodwa lwezinto ezihlosiwe ze-sputtering.Ngakho-ke yini into ehlosiwe?Kungani okuhlosiwe kubaluleke kangaka?Namuhla sizokhuluma ngalokho okuhlosiwe!
Kuyini okuhlosiwe?
Kalula nje, okuqondiwe kuyizinto ezihlosiwe ezihlaselwe izinhlayiya ezishajwa ngesivinini esikhulu.Ngokufaka esikhundleni sezinto ezihlosiwe ezihlukene (njenge-aluminium, ithusi, insimbi engagqwali, i-titanium, okuqondiwe kwe-nickel, njll.), amasistimu efilimu ahlukene (njengamafilimu aqinile, angagugi, alwa nokugqwala, njll.) angatholakala.
Okwamanje, (ukuhlanzeka) okuhloswe ngakho ukugawula kungahlukaniswa kube:
1) Izinhloso zensimbi (i-aluminium yensimbi ehlanzekile, i-titanium, ithusi, i-tantalum, njll.)
2) Okuqondiwe kwengxubevange (nickel chromium alloy, nickel cobalt alloy, njll.)
3) Izinhloso ze-Ceramic compound (ama-oxides, ama-silicides, ama-carbides, ama-sulfide, njll.).
Ngokushintshashintsha okuhlukahlukene, ingahlukaniswa kube: okuqondiwe okude, okuqondiwe kwesikwele, kanye nethagethi eyindilinga.
Ngokuya ngezinkambu ezihlukene zohlelo lokusebenza, zingahlukaniswa zibe: okuqondiwe kwe-semiconductor chip, okuqondiwe kwesibonisi sephaneli eyisicaba, okuqondiwe kweseli yelanga, okuqondiwe kokugcinwa kolwazi, okuqondiwe okulungisiwe, okuqondiwe kwedivayisi ye-elekthronikhi, nokunye okuhlosiwe.
Ngokubheka lokhu, bekufanele ngabe uthole ukuqonda okuhlosiwe kokuhlanzeka okuphezulu, kanye ne-aluminium, i-titanium, ithusi, ne-tantalum esetshenziswa ekuhlosweni kwensimbi.Ekwenziweni kwe-wafer ye-semiconductor, inqubo ye-aluminium ngokuvamile iyindlela eyinhloko yokukhiqiza ama-wafer angama-200mm (amayintshi angu-8) nangaphansi, futhi izinto ezihlosiwe ezisetshenziswayo ikakhulukazi i-aluminium kanye nezakhi ze-titanium.Ukukhiqizwa kwe-wafer engu-300mm (12 inch), ikakhulukazi kusetshenziswa ubuchwepheshe obuthuthukisiwe bokuxhuma i-copper, ikakhulukazi kusetshenziswa ithusi ne-tantalum.
Wonke umuntu kufanele aqonde ukuthi yini into ehlosiwe.Sekukonke, ngobubanzi obandayo bokusetshenziswa kwama-chip kanye nesidingo esandayo emakethe yama-chip, nakanjani kuzoba nokwanda kwesidingo sezinto ezine ezivamile zensimbi yamafilimu amancane embonini, okuyi-aluminium, i-titanium, i-tantalum, nethusi.Futhi okwamanje, asikho esinye isisombululo esingangena esikhundleni salezi zinto ezine zensimbi ezincanyana zefilimu.
