Claim Text:
1. A solid-state imaging device, comprising: a semiconductor substrate having a front surface provided with a plurality of light receiving sections in a lattice pattern; light condensing sections provided for the light receiving sections at a back surface of the semiconductor substrate, the light condensing sections each including a flat plane section that is parallel to the front surface of the semiconductor substrate and a plurality of inclined surfaces surrounding the flat plane section and being inclined relative to the front surface of the semiconductor substrate, wherein a shape of the flat plane section in a cross section parallel to the front surface of the semiconductor substrate is substantially square, an area of the flat plane section in a cross section parallel to the front surface of the semiconductor substrate is larger than an area of a respective light receiving section in a cross section parallel to the front surface of the semiconductor substrate, and the inclined surfaces of adjacent light condensing sections being in contact with each other and forming a V-shaped groove on the back surface of the semiconductor substrate; and a wiring layer including metal wirings, the wiring layer provided on the front surface of the semiconductor substrate.
