Patent ID: 8154056

Claim:
A solid-state imaging device comprising: a substrate; a plurality of pixels arranged in a matrix of rows and columns on the substrate, each pixel configured to convert incident light into electrical charges; and a plurality of charge-transfer portions, each located on side of a respective column of the pixels so that, expect of a last column, each charge-transfer portion is located between adjacent columns of pixels, wherein, each charge-transfer portion includes vertical transfer resistor, a first transfer electrode layer and a second transfer electrode layer stacked on the substrate with the first transfer electrode layer between the second transfer electrode layer and the substrate, and the vertical transfer resistor is located under the first transfer electrode layer, each first transfer electrode layer includes first, second, third and fourth first transfer electrodes arranged in that order along a column direction, each second transfer electrode layer includes first and second second transfer electrodes arranged in that order along the column direction, the first second transfer electrode is located to overlap the second first transfer electrode and the third first transfer electrode, and the second second transfer electrode is located to overlap the fourth first transfer electrode, the first second transfer electrode is connected to the second first transfer electrode and the second second transfer electrode is connected to the fourth first transfer electrode by means of respective contact layers, in cross-section along a row direction, each of the second and fourth first transfer electrodes is wider than each of the first and second second transfer electrodes, respectively, wirings between adjacent rows of pixels, a first wiring connected to all first first transfer electrodes, a second wiring connected to all first second transfer electrodes, a third wiring connected to all third first transfer electrodes and a fourth wiring connected to all second second transfer electrodes, and each of the first and second second transfer electrodes is located in a vicinity of the respective contact layers.
