Patent ID: 7534644

Claim:
A method of producing a solid-state imaging device, 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, said method including the steps of: forming the plurality of light receiving portions in the first direction and the second direction; forming the transfer channels extending in the second direction arranging each of the transfer channel between the neighboring light receiving portions; forming the first transfer electrodes on said transfer channels, the neighboring first transfer electrodes positioned at both sides of the light receiving portion being connected in the first direction; forming the second transfer electrodes on said transfer channels in the same layer of said first transfer electrodes; and forming 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.
