Title:
SOLID-STATE IMAGE SENSOR AND CAMERA
Document Type and Number:
Japanese Patent JP2016225597
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a technique advantageous for preventing the leakage of a surplus electric charge, which moves from one of a pair of charge storage regions to the other, into a floating diffusion.SOLUTION: A solid-state image sensor includes first conductivity type photoelectric converter units R1 and R2, a second conductivity type impurity region R3 formed therebetween, a first conductivity type impurity region R4, transfer gate electrodes G1 and G2 and a second conductivity type impurity region R5. The concentration of the second conductivity type impurity in the impurity region R5 is higher than the concentration of the second conductivity type impurity in the impurity region R3.SELECTED DRAWING: Figure 2
