Abstract:
1. A solid-state imaging device, comprising: a plurality of pixels arranged on a substrate, each pixel of the plurality of pixels including a light sensing portion configured to generate a signal electric charge according to incident light; an on-chip micro lens at a light incident side above the light sensing portion, wherein the on-chip micro lens includes, in a plane that is perpendicular to a surface of the substrate, a single convex portion having a rectangular shape formed of a material that extends continuously, without gaps, over the entire light sensing portion, and a rectangular concave portion between adjacent pixels; and a planarized lens layer disposed on the single convex portion having the rectangular shape, wherein the planarized lens layer has a light incident surface that is planarized, wherein a refraction index of the planarized lens layer is larger than a refraction index of air and is smaller than a refraction index of the on-chip micro lens.
