The method includes forming an opening within a front side surface of a substrate; forming a conformal implant layer on bottom and sidewall surfaces of the opening; growing a first epitaxial layer on the bottom and the sidewall surfaces of the opening; depositing a second epitaxial layer on the first epitaxial layer to fill the opening, where the second epitaxial layer forms a radiation-sensing region. The method further includes depositing a stack on exposed surfaces of the second epitaxial layer, where the stack includes alternating pairs of a high-refractive index material layer and a low-refractive index material layer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image sensor with improved light conversion efficiency","description":"The present disclosure describes a method for the formation of mirror micro-structures on radiation-sensing regions of image sensor devices.
