Indlela yokuhlanza isikebhe se-graphite se-PECVD？| I-VET Energy
ngumlawuli ngomhlaka-24-12-23
1. Ukuvuma ngaphambi kokuhlanza 1) Uma isikebhe/isithwali se-PECVD graphite sisetshenziswa izikhathi ezingaphezu kuka-100 kuya ku-150, umqhubi udinga ukuhlola isimo sokumboza ngesikhathi. Uma kukhona ukumboza okungajwayelekile, kudinga ukuhlanzwa nokuqinisekiswa. Umbala wokumboza ojwayelekile we...

Isimiso sesikebhe se-graphite se-PECVD se-solar cell (coating) | VET Energy
ngumlawuli ngomhlaka-24-12-23
Okokuqala, sidinga ukwazi i-PECVD (i-Plasma Enhanced Chemical Vapor Deposition). I-Plasma iwukuqiniswa kokunyakaza kokushisa kwama-molecule ezinto ezibonakalayo. Ukungqubuzana phakathi kwawo kuzokwenza ama-molecule egesi abe yi-ionized, futhi izinto zizoba yingxube ye-fr...

Izimoto ezintsha zamandla zikuthola kanjani ukubhuleka okusiza nge-vacuum? | I-VET Energy
ngumlawuli ngomhlaka-24-12-18
Izimoto ezintsha zamandla azinazo izinjini zikaphethiloli, ngakho-ke zikuthola kanjani ukubhuleka okusizwa yi-vacuum ngesikhathi sokubhuleka? Izimoto ezintsha zamandla ikakhulukazi zithola usizo lwe-brake ngezindlela ezimbili: Indlela yokuqala ukusebenzisa uhlelo lwe-electric vacuum booster braking. Lolu hlelo lusebenzisa i-electric vac...

Kungani sisebenzisa i-UV tape ukuze sihlukanise ama-wafer? | VET Energy
ngu-admin ngomhlaka-24-12-16
Ngemva kokuba i-wafer isidlule enkambisweni yangaphambilini, ukulungiswa kwe-chip kuqediwe, futhi kudingeka inqunywe ukuze kuhlukaniswe ama-chips ku-wafer, bese ekugcineni ipakishwa. Inqubo yokusika i-wafer ekhethelwe ama-wafer anobukhulu obuhlukene nayo ihlukile: ▪ Ama-wafer anobukhulu obungaphezulu ...

I-wafer warpage, yini okufanele uyenze?
ngu-admin ngomhlaka-24-12-16
Enqubweni ethile yokufaka, kusetshenziswa izinto zokupakisha ezine-coefficients yokwandisa ukushisa ehlukene. Ngesikhathi senqubo yokufaka, i-wafer ibekwa endaweni yokufaka, bese kwenziwa izinyathelo zokushisa nokupholisa ukuze kuqedwe ukufakwa. Kodwa-ke, ngenxa yokungafani phakathi...

Kungani izinga lokusabela kwe-Si ne-NaOH lishesha kune-SiO2?
ngumlawuli ngomhlaka-24-12-10
Kungani izinga lokusabela kwe-silicon ne-sodium hydroxide lingadlula ele-silicon dioxide lingahlaziywa kusukela kulezi zici ezilandelayo: Umehluko emandleni esibopho samakhemikhali ▪ Ukusabela kwe-silicon ne-sodium hydroxide: Lapho i-silicon isabela ne-sodium hydroxide, amandla esibopho se-Si-Si phakathi kwe-silicon ato...

Kungani i-silicon ilukhuni kangaka kodwa ibuthakathaka kangaka?
ngumlawuli ngomhlaka-24-12-10
I-Silicon iyikristalu ye-athomu, ama-athomu ayo axhunywe komunye nomunye ngama-covalent bonds, akha isakhiwo senethiwekhi yendawo. Kulesi sakhiwo, ama-covalent bonds phakathi kwama-athomu aqondisa kakhulu futhi anamandla aphezulu e-bond, okwenza i-silicon ibonise ubulukhuni obukhulu lapho imelana namandla angaphandle...

Kungani izindonga eziseceleni zigoba ngesikhathi sokusika okomile?
ngumlawuli ngomhlaka-24-12-03
Ukungalingani kwe-ion bombardment Ukuchoma okomile ngokuvamile kuyinqubo ehlanganisa imiphumela yomzimba neyamakhemikhali, lapho ukuchoma kwe-ion kuyindlela ebalulekile yokuchoma ngokomzimba. Ngesikhathi senqubo yokuchoma, i-engeli yesigameko kanye nokusatshalaliswa kwamandla kwama-ion kungase kungalingani. Uma i-ion incide...

Isingeniso kubuchwepheshe obuthathu obuvamile be-CVD
ngumlawuli ngomhlaka-24-12-03
Ukufakwa komphunga wamakhemikhali (i-CVD) ubuchwepheshe obusetshenziswa kakhulu embonini ye-semiconductor ukufaka izinto ezahlukahlukene, kufaka phakathi uhla olubanzi lwezinto zokufaka umswakama, izinto eziningi zensimbi kanye nezinto ze-alloy zensimbi. I-CVD ubuchwepheshe bendabuko bokulungiselela ifilimu encane. Isisekelo sayo...
