22/03/25Imodeli Yenzwa ibhekisela ohlotsheni lobuchwepheshe benzwa yekhamera esetshenziswayo. Wonke amakhamera ebangeni lethu asebenzisa ubuchwepheshe be-'CMOS' (Complimentary Metal-Oxide Semiconductor) kuhlu lwamaphikseli azwela ukukhanya akha isithombe. Leli izinga lemboni lezithombe ezisebenza kahle kakhulu. Kunezinhlobo ezimbili ze-CMOS: Front-side illuminated (FSI) kanye ne-back-side illuminated (BSI).
Izinzwa ezikhanyisiwe ezihlangothini lwangaphambili zisebenzisa igridi yezintambo nezinto zikagesi phezu kwamaphikseli azwela ukukhanya ukuze zilawule inzwa. Igridi yamalensi amancane igxilisa ukukhanya kudlule izintambo endaweni ye-silicon ebona ukukhanya. Lezi izinzwa zekhamera ezilula kakhulu ukwenziwa futhi angabizi kakhulu, okusho ukuthi amakhamera akhanyiswe ngaphambili ngokuvamile awabizi kakhulu. Izinzwa ezikhanyisiwe ezingemuva ziphenyisisa le jiyomethri yenzwa, ngama-photon ashaya ngokuqondile i-silicon ebona ukukhanya, ngaphandle kwezintambo noma amalensi amancane endleleni. I-silicon substrate kufanele incitshwe ngokunembe kakhulu kuze kufike ku-1.1 μm ubukhulu ukuze lo mklamo usebenze, okusho ukuthi izinzwa ze-BSI ngezikhathi ezithile zibizwa ngokuthi izinzwa ezi-back-thinned (BT). Izinzwa ezikhanyisiwe emuva zinikeza ukuzwela okukhulu, ngokushintshanisa izindleko ezikhulayo nobunzima bokukhiqiza.
Ukucaciswa okubaluleke kakhulu okufanele ukucabangele lapho ukhetha phakathi kwamakhamera akhanyisiwe angaphambili nangemuva ohlelo lwakho lokusebenza lokuthwebula yilokho okudingekayo I-Quantum Efficiency. Ungafunda okwengeziwe ngalokho lapha[isixhumanisi].
