Kuzo zonke izinqubo ezihilelekile ekwakhiweni kwe-chip, isiphetho sokugcina se-wafer izosikwa ibe yifa lomuntu ngamunye futhi ihlanganiswe emabhokisini amancane, avalelwe aveze izikhonkwane ezimbalwa kuphela. I-chip izohlolwa ngokusekelwe embundwini wayo, ukumelana, amanani amanje, kanye ne-voltage, kodwa akekho ozocabangela ...Funda kabanzi -
Ukwethulwa Okuyisisekelo Kwenqubo Yokukhula Kwe-SiC Epitaxial
I-Epitaxial layer ifilimu ethize yekristalu eyodwa ekhule ku-wafer ngenqubo ye-ep ·itaxial, futhi i-substrate wafer nefilimu ye-epitaxial kuthiwa yi-epitaxial wafer. Ngokukhulisa ungqimba lwe-silicon carbide epitaxial ku-conductive silicon carbide substrate, i-silicon carbide homogeneous epitaxial...Funda kabanzi -
Amaphuzu abalulekile okulawulwa kwekhwalithi yenqubo yokupakisha ye-semiconductor
Amaphuzu Abalulekile Okulawulwa Kwekhwalithi Kunqubo Yokufaka I-Semiconductor Okwamanje, ubuchwepheshe benqubo yokupakisha kwe-semiconductor buye bathuthuka kakhulu futhi bathuthukiswa kakhulu. Kodwa-ke, ngokombono ophelele, izinqubo nezindlela zokupakishwa kwe-semiconductor azikafinyeleli kokuphelele kakhulu...Funda kabanzi -
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-SemiconductorInqubo 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. Uma i-X-ray beam iqondiswe kubuso bekristalu obufunwayo, i-engeli ye-diffracted beam inquma umumo wekristalu...Funda kabanzi -
