Abstract:
A method for fabricating a solid state image sensor comprising the steps of:forming a plurality of transfer lines over a semiconductor substrate and receiving clock signals, at least one of the plurality of transfer lines having a transparent conductive material;forming a plurality of transfer electrodes connected to the transfer lines;forming a plurality of photoelectric conversion regions under a surface of the substrate and generating image signals; andforming a plurality of charge transfer regions under the surface of the substrate transferring the image signals from the photoelectric conversion regions in response to the clock signals from the transfer lines,wherein the step of forming the plurality of transfer lines includes the steps of:forming first transfer lines at a first side of the photoelectric conversion regions; andforming second transfer lines at a second side of the photoelectric conversion regions, the second transfer lines including the at least one transfer line having the transparent conductive material.
