An exemplary includes forming a plurality of radiation-sensing regions in a substrate. The substrate has a front surface, a back surface, and a sidewall that extends from the front surface to the back surface. The exemplary method further includes forming an interconnect structure over the front surface of the substrate, removing a portion of the substrate to expose a metal interconnect layer of the interconnect structure, and forming a bonding pad on the interconnect structure in a manner so that the bonding pad is electrically coupled to the exposed metal interconnect layer and separated from the sidewall of the substrate."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Back side illuminated image sensor with reduced sidewall-induced leakage","description":"Provided is a method of fabricating an image sensor device.
