Solid-state imaging device, method for driving the same, method for manufacturing the same, camera, and method for driving the same

摘要

A solid-state imaging device includes a two-dimensional array of photosensor sections on a semiconductor substrate, and a vertical transfer section including two-layer vertical transfer electrodes. The photosensor sections store signal charges generated by photoelectric conversion. The vertical transfer section reads signal charges from the photosensor sections and vertically transfers the read signal charges. The two-layer vertical transfer electrodes have first transfer electrode layers and second transfer electrode layers, and the first transfer electrode layers serve as read electrodes for reading the signal charges from the photosensor sections. The first transfer electrode layers have a larger electrode width with respect to the photosensor sections than the second transfer electrode layers.
