Patent ID: 8390706

Claim:
A method for manufacturing a solid-state imaging device, the method comprising the steps of: forming a plurality of photoelectric conversion portions at the imaging surface of a semiconductor substrate; forming an impurity diffusion region among the plurality of photoelectric conversion portions, the impurity diffusion region functioning as an element isolation portion configured to isolate the plurality of photoelectric conversion portions on the imaging surface and to isolate groups of photoelectric conversion portions from each other; forming a light shielding portion above the element isolation portion, the light shielding portion being configured to stop incident light from entering the element isolation portion on the imaging surface; forming the gate electrodes of a plurality of pixel transistors on the imaging surface, the plurality of pixel transistors being configured to read out and output signal charge, generated in the plurality of photoelectric conversion portions, as data signals; and forming a conductive layer before the light shielding portion forming step and the gate electrode forming step are performed, the conductive layer being formed by forming the layer of a conductive material having a light blocking effect so that a region that includes a portion where the light shielding portion is formed and portions where the gate electrodes of the plurality of pixel transistors are formed is coated on the imaging surface, wherein, in the light shielding portion forming step and the gate electrode forming step, the light shielding portion and the gate electrodes are simultaneously formed by patterning the conductive layer.
