Abstract
A solid-state image sensor includes pixels and lenses. Each of the pixels on a semiconductor substrate includes a photodetecting section which photoelectrically converts incident light. Each of the lenses condenses the incident light on the photodetecting section. The lenses have a fixed curvature on an incident surface for the incident light. A top of the incident surface of each of the lenses is at a position different from that of a center of a bottom surface of each of the lenses in a direction horizontal to the bottom surface.

A solid-state image sensor comprising:
- pixels on a semiconductor substrate, each of the pixels including a photodetecting section which photoelectrically converts incident light;
- and
- lenses which condense the incident light on the photodetecting section, the lenses having a fixed curvature on an incident surface for the incident light, a top of the incident surface of each of the lenses being at a position different from that of a center of a bottom surface of each of the lenses in a direction horizontal to the bottom surface.
A solid-state image sensor comprising:
- pixels on a semiconductor substrate, each of the pixels including a photodetecting section which photoelectrically converts incident light;
- unit cells each including the pixels and a signal output section which outputs information corresponding to signal charges read from the pixels;
- a light receiving section in which the unit cells are arranged;
- lenses formed above the light receiving section and each provided for the corresponding one of the pixels to condense the incident light on the photodetecting section of the corresponding pixel, the lenses having a fixed curvature on an incident surface for the incident light, a top of incident surface of each of the lenses being at a position different from that of a center of a bottom surface of each of the lenses in a direction horizontal to the bottom surface.
