Abstract
An image sensor device includes a semiconductor device, a plurality of photo sensitive regions, a dielectric layer, a grid structure, and a plurality of convex dielectric lenses. The photo sensitive regions are in the semiconductor substrate. The dielectric layer is over a backside surface of the semiconductor substrate. The grid structure is over a backside surface of the dielectric layer. The grid structure includes a plurality of grid lines. Each of the grid lines comprises a lower portion and an upper portion forming an interface with the lower portion. The convex dielectric lenses are alternately arranged with the grid lines over the backside surface of the dielectric layer. Apexes of the plurality of convex dielectric lenses are higher than an interface between the upper portion and the lower portion of each of the grid lines.
