Izinselelo kuNqubo yokupakisha yeSemiconductor
Amasu amanje okufakwa kwe-semiconductor ayathuthuka kancane kancane, kodwa izinga lapho okokusebenza okuzenzakalelayo nobuchwepheshe okwamukelwa khona ekufakweni kwe-semiconductor linquma ngokuqondile ukufezeka kwemiphumela elindelekile. Izinqubo ezikhona zokupakisha ze-semiconductor zisahlupheka ngenxa...Funda kabanzi -
Ucwaningo Nokuhlaziywa Kwenqubo Yokufaka I-Semiconductor
Uhlolojikelele Lwenqubo Ye-semiconductor Inqubo ye-semiconductor ngokuyinhloko ihilela ukusebenzisa ubuchwepheshe be-microfabrication kanye nefilimu ukuze kuxhunywe ngokugcwele ama-chips nezinye izici ngaphakathi kwezifunda ezihlukahlukene, njengama-substrates namafreyimu. Lokhu kusiza ukukhishwa kwamatheminali okuhola kanye ne-encapsulation nge ...Funda kabanzi -
Amathrendi Amasha embonini ye-Semiconductor: Ukusetshenziswa Kobuchwepheshe Bokumboza Okuvikelayo
Imboni ye-semiconductor ibona ukukhula okungakaze kubonwe ngaphambili, ikakhulukazi endaweni ye-silicon carbide (SiC) power electronics. Njengoba kunezindwangu eziningi eziyisilucwe ezisakhiwa noma ezinwetshwa ukuze kuhlangatshezwane nesidingo esikhulayo samadivayisi e-SiC ezimotweni zikagesi, lokhu ...Funda kabanzi -
Yiziphi izinyathelo eziyinhloko ekucutshungulweni kwama-substrates e-SiC?
Indlela esikhiqiza ngayo izinyathelo zokucubungula zama-substrates e-SiC zimi kanje: 1. I-Crystal Orientation: Ukusebenzisa i-X-ray diffraction ukuze uqondise i-crystal ingot. Lapho i-X-ray beam iqondiswe kubuso bekristalu obufunwayo, i-engeli ye-diffracted beam inquma i-crystal orienta...Funda kabanzi -
Into ebalulekile enquma ikhwalithi yokukhula kwe-silicon eyodwa ye-crystal - insimu eshisayo
Inqubo yokukhula ye-silicon eyodwa ye-crystal yenziwa ngokuphelele emkhakheni oshisayo. Inkambu eshisayo ekahle ivumela ukuthuthukisa ikhwalithi yekristalu futhi inokusebenza kahle kwekristalu okuphezulu. Idizayini yenkundla eshisayo inquma kakhulu izinguquko nezinguquko...Funda kabanzi -
Kuyini ukukhula kwe-epitaxial?
Ukukhula kwe-Epitaxial ubuchwepheshe obukhulisa ungqimba olulodwa lwekristalu ku-crystal substrate eyodwa (i-substrate) ene-crystal orientation efana ne-substrate, njengokungathi i-crystal yasekuqaleni inwetshiwe ngaphandle. Lesi sendlalelo sekristalu esanda kukhula singahluka ku-substrate ngokuya nge-c...Funda kabanzi -
Uyini umehluko phakathi kwe-substrate ne-epitaxy?
