22/03/25I-Sensor Model ibhekisa kuhlobo lobuchwepheshe boluvo lwekhamera esetyenzisiweyo. Zonke iikhamera kuluhlu lwethu zisebenzisa itekhnoloji ye-'CMOS' (i-Complimentary Metal-Oxide Semiconductor) kuluhlu lwepixel olungevani nokukhanya okwenza umfanekiso. Lo ngumgangatho weshishini lomfanekiso osebenza kakhulu. Kukho izinto ezimbini ezahlukeneyo zeCMOS: Icala langaphambili elikhanyayo (FSI) kunye necala elingasemva elikhanyayo (BSI).
Izinzwa ezikhanyisiweyo zecala langaphambili zisebenzisa igridi yocingo kunye ne-electronics ngaphezulu kweepikseli ezilula ukukhanya ukulawula inzwa. Igridi yeelensi ezincinci igxininise ekukhanyeni okudlulileyo kwiingcingo ukuya kwindawo yesilicon ebona ukukhanya. Ezi zezona zivamvo zekhamera zilula ukwenziwa kwaye ezona zixabisa kakhulu, oko kuthetha ukuba iikhamera ezikhanyiswe ngaphambili zidla ngokungabizi kakhulu. Ngasemva ngasemva izinzwa ezikhanyisiweyo zijika le geometry yoluvo ngeenxa zonke, ngeefotoni ezibetha ngokuthe ngqo isilicon ebona ukukhanya, kungekho cingo okanye iilensi ezincinci endleleni. I-silicon substrate kufuneka icuthwe ngokuchanekileyo ukuya kuthi ga kwi-1.1 μm ubukhulu ukuze olu luyilo lusebenze, oku kuthetha ukuba abenzi boluvo be-BSI ngamanye amaxesha babizwa ngokuba ngabava-nzwa be-back-thinned (BT). Izinzwa ezikhanyiselwe ngasemva zibonelela ngovakalelo olukhulu, ngokutshintshiselana ngeendleko ezongezelelekileyo kunye nobunzima bokwenziwa.
Eyona ngcaciso ibalulekileyo ekufuneka uyiqwalasele xa ukhetha phakathi kweekhamera ezikhanyisiweyo zangaphambili nangasemva kwisicelo sakho sokucinga yinto efunekayo ngokuSebenza kweQuantum. Unokufunda ngakumbi malunga naloo nto apha [ikhonkco].
