22/03/25Qaabka dareemayaasha waxa loola jeedaa nooca tignoolajiyada dareemayaasha kamarada ee la isticmaalo. Dhammaan kamaradaha ku jira kala duwanaanshahayaga waxay isticmaalaan tignoolajiyada 'CMOS' (Complimentary Metal-Oxide Semiconductor) ee pixel array-xasaasiga ah ee sameeya sawirka. Tani waa heerka warshadaha ee sawir-qaadista waxqabadka sare. Waxaa jira laba nooc oo CMOS ah: Dhinaca hore ee iftiimay (FSI) iyo dhinaca dambe ee iftiinka (BSI).
Dareemayaasha dhinaca hore ee iftiinka leh waxay isticmaalaan xadhkaha fiilooyinka iyo elektiroonigga sare ee pixel-yada xasaasiga ah si ay u maamulaan dareeraha. Shabaqyada lenses-yar-yar ayaa diiradda saaraya iftiinka dhaafay fiilooyinka ilaa aagga silikoon ee iftiiminaya. Kuwani waa dareemayaasha kamaradaha ugu fudud ee la soo saaro iyo kuwa ugu kharashka badan, taas oo macnaheedu yahay kamaradaha hore u iftiimiyay caadi ahaan waa ka qaalisan yihiin. Dareemayaasha iftiimaya ee dhinaca dambe ayaa ku rogaya joomatari dareeraha ah, oo leh sawir-qaadayaal si toos ah u garaacaya silikoon-ogaanshaha iftiinka, iyada oo aan lahayn fiilooyinka ama muraayadaha yaryar ee jidka. Substrate-ka silikoonku waa inuu ahaadaa mid si sax ah loo khafiifiyay ilaa 1.1 μm dhumucdiisuna tahay si naqshadani u shaqeyso, taasoo la micno ah in dareemayaasha BSI mararka qaarkood loogu yeero dareemeyaasha gadaal-khafiifsan (BT). Dareemayaasha gadaal u iftiimay waxay bixiyaan dareen weyn, beddelka qiimaha korodhka iyo kakanaanta wax soo saarka.
Tilmaamaha ugu muhiimsan ee la tixgeliyo marka la dooranayo inta u dhaxaysa kamaradaha iftiinka hore iyo kan dambe ee codsigaaga sawir-qaadista waa waxa loo baahan yahay waxtarka Quantum. Waxaad wax badan oo arrintaas ku saabsan ka akhriyi kartaa halkan[link].
