Abstract:
1. A method of manufacturing a solid-state imaging device, comprising: arranging light-receiving sensor portions each constituting a pixel in the form of a matrix, the matrix having columns aligned in a vertical direction and rows aligned in a horizontal direction; forming charge-transfer portions on either side of the columns of said pixels by lamination; and forming transfer electrodes in the charge-transfer portions to include a first, second, third and fourth transfer electrodes formed of a first electrode layer arranged along a column direction, and first and second transfer electrodes formed of a second electrode layer arranged along the column direction, the first and second transfer electrodes of the second electrode layer being disposed in the vertical direction above the charge-transfer portions in a vicinity of a contact to decrease the width of the charge-transfer portions in the horizontal direction and increase the light receiving sensor portions in the vertical direction, wherein, the first electrode layer is laminated below a portion of the second electrode layer between the pixels, a contact layer is formed in an insulating layer between at least one of the plurality of transfer electrodes of the first electrode layer and the first and second transfer electrodes of the second electrode layer, the first transfer electrode of the second electrode layer is located to overlap with the second and third transfer electrodes of the first electrode layer and the second transfer electrode of the second electrode layer is located to overlap with the fourth transfer electrode of the first electrode layer, and the first transfer electrode of the second electrode layer is connected to the second transfer electrode of the first electrode layer and the second transfer electrode of the second electrode layer is connected to the fourth transfer electrode of the second electrode layer by means of respective contact layers.
