Izici Zomkhiqizo
I-1, Izinga eliphezulu lokuvikelwa kwemvelo: Ukufakwa okukhethiwe kungafinyelelwa ngaphandle kokusebenzisa izisekelo zemvelo ezifana ne-TMAH.
I-2, Izindleko zokukhiqiza eziphansi: Ukusebenzisa i-NaOH/KOH njengoketshezi lokufaka, izindleko ziphansi kakhulu kunenqubo yokupholisha ne-etching ye-asidi.
3, Ukusebenza kahle kwe-etching: Uma kuqhathaniswa nenqubo yokupholisha i-asidi ne-etching, ukusebenza kahle kwebhethri kukhuphuka ngaphezu kuka-0.15%.
Izicelo Zomkhiqizo
1, Lo mkhiqizo ngokuvamile ulungele izinqubo zebhethri ze-Perc ne-Topcon;
2, Ifanele amakristalu eyodwa 210, 186, 166, kanye 158 imininingwane.
Imiyalo yokusetshenziswa
1, Engeza inani elifanele le-alkali ethangini (1.5-4% ngokusekelwe kusilinganiso sevolumu ye-KOH/NAOH)
2, Engeza inani elifanele lalo mkhiqizo ethangini (1.0-2% ngokusekelwe kwisilinganiso sevolumu)
3, Fudumeza uketshezi lwethangi lokupholisha lube ku-60-65°C
4, Faka isicwecwana se-silicon esine-PSG engemuva sikhishiwe ethangini lokupholisha, isikhathi sokusabela singu-180s-250s.
5, Ukuncipha kwesisindo okunconyiwe ohlangothini ngalunye: 0.24-0.30g (umthombo we-wafer ongu-210, eminye imithombo iguqulwa ngezilinganiso ezilinganayo) amaseli elanga elanga elilodwa kanye ne-polycrystalline PERC
Izinyathelo zokuzivikela
1, Izithasiselo zidinga ukugcinwa kude nokukhanya.
2, Uma umugqa wokukhiqiza ungakhiqizi, uketshezi kufanele lugcwaliswe futhi lukhishwe njalo ngemizuzu engama-30.Uma kungekho ukukhiqizwa isikhathi esingaphezu kwamahora angu-2, kunconywa ukuba ukhiphe futhi uphinde ugcwalise uketshezi.
3, Ukulungisa iphutha komugqa omusha kudinga ukuklanywa kwe-DOE okusekelwe kunqubo ngayinye yomugqa wokukhiqiza ukuze kuzuzwe ukufanisa inqubo, ngaleyo ndlela kukhuliswe ukusebenza kahle.Inqubo enconyiwe ingabhekiselwa ekususeni iphutha.
