Document Type and Number:
Japanese Patent JP6526115
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a technique advantageous to the improvement of sensitivity in a solid state image sensor having a configuration where a plurality of pixels are assigned to each microlens.SOLUTION: A solid state image sensor including a semiconductor substrate having a first surface and a second surface opposite to each other further includes a pixel array where a plurality of pixel sets are arranged, and a plurality of microlenses arranged so that one microlens is assigned to each pixel set. Each pixel set includes a plurality of pixels, and each pixel includes a photoelectric conversion part and a wiring pattern constituting a part of a circuit in the pixel. The photoelectric conversion part is formed on the semiconductor substrate, the wiring pattern is arranged on the first surface of the semiconductor substrate, and the plurality of microlenses are arranged on the second surface of the semiconductor substrate.SELECTED DRAWING: Figure 3
