Abstract:
1. A method for producing a solid-state imaging device, comprising steps of: a first step of forming transfer electrodes on a substrate having a plurality of light-sensing portions through a gate insulating layer so that the light-sensing portions are exposed; after the first step, a second step of forming a planarized insulating layer on the substrate to cover the transfer electrodes formed on the substrate; after the second step, a third step of forming openings in the planarized insulating layer so that each of the transfer electrodes has a part thereof exposed out of the planarized insulating layer at a predetermined position; after the third step, a fourth step of forming a wiring material layer so that the openings are filled with the wiring material layer; after the fourth step, a fifth step of forming a resist layer on the wiring material layer; after the fifth step, a sixth step of exposing and developing the resist layer so that only the resist layer in a predetermined area covering the openings is left; and after the sixth step, a seventh step of patterning the wiring material layer using the exposed and developed resist layer to form connection wirings which are connected to the transfer electrodes by the openings.
