Abstract
A solid-state imaging device capable of reducing an eclipse (blocking) of an incident light at a circumferential portion of a light receiving portion and realizing a larger angle of view and high-speed driving. A single-layer transfer electrode configuration of forming first transfer electrodes and second transfer electrodes by one polysilicon layer is adopted. Two shunt wirings extending in a horizontal direction are formed on the first transfer electrodes connected in a horizontal direction and, for example, four-phase transfer pulses are supplied to first transfer electrodes and second transfer electrodes on transfer channels through low-resistance shunt wirings extending in the horizontal direction.
Claims5
A camera, comprising:
- an optical lens;
- and
- a solid-state imaging device for converting an image obtained through the optical lens to an electric signal,
- said solid-state imaging device comprising:
- a plurality of light receiving portions arranged in a first direction and a second direction perpendicular to the first direction;
- a plurality of transfer channels extending in the second direction, each being arranged between the neighboring light receiving portions;
- a plurality of first transfer electrodes arranged on said transfer channels, the neighboring first transfer electrodes positioned at both sides of the light receiving portion being connected in the first direction;
- a plurality of second transfer electrodes arranged in the same layer of said first transfer electrodes, on said transfer channel;
- and
- low-resistance wirings of which the number corresponds to the number of transfer electrodes, extending over said first transfer electrode in the first direction, and having a lower resistance than those of said first transfer electrodes and said second transfer electrodes, each of said low-resistance wirings being connected to the first transfer electrode and the second transfer electrode on each transfer channel through a connecting portion.
