Abstract:
1. A solid-state imaging device comprising a plurality of vertical charge transferring portions, and a horizontal charge transferring portion that is connected to at least one end of the vertical charge transferring portions, receives charges transferred from the vertical charge transferring portions and transfers the charges, wherein each of the vertical charge transferring portions includes a vertical transfer channel region of a first conductivity, an element isolating region of a second conductivity formed so as to be adjacent to the vertical transfer channel region of the first conductivity, a plurality of vertical transfer electrodes and a final vertical transfer electrode formed on the vertical transfer channel region of the first conductivity, and a vertical well region of the second conductivity formed below the vertical transfer channel region of the first conductivity, the horizontal charge transferring portion includes a horizontal transfer channel region of a first conductivity, and a plurality of horizontal transfer electrodes formed on the horizontal transfer channel region of the first conductivity, and a horizontal well region of the second conductivity formed below the horizontal transfer channel region of the first conductivity, in a connection portion between each of the vertical charge transferring portions and the horizontal charge transferring portion, the vertical transfer channel region of the first conductivity, the element isolating region of the second conductivity and the vertical well region of the second conductivity extend from each of the vertical charge transferring portions, and a part of the horizontal transfer electrodes is overlapped on a portion of the vertical transfer channel region of the first conductivity that extends in the connection portion, and end portions of the portions of the vertical transfer channel region of the first conductivity and the vertical well region of the second conductivity that extend in the connection portion on the side of the horizontal charge transferring portion are positioned more on the side of the horizontal charge transferring portion than an end portion of the final vertical transfer electrode on the side of the horizontal charge transferring portion, and are positioned within 1.5 μm from the end portion of the element isolating region of the second conductivity on the side of the horizontal charge transferring portion.
