Abstract:
1. A manufacturing method of a solid-state imaging apparatus, comprising: a step of forming first transfer electrodes of a vertical transfer CCD and a horizontal transfer CCD on a semiconductor substrate; a step of forming first oxide films over each of the first transfer electrodes; a step of opening a region that includes only the first transfer electrodes of the horizontal transfer CCD and forming a resist layer which covers all other regions; a step of selectively removing the first oxide films formed over the first transfer electrodes of the horizontal transfer CCD; a step of forming a potential barrier region by implanting ions between the first transfer electrodes of the horizontal transfer CCD; a step of removing said resist layer; a step of forming a second oxide film over each of the first transfer electrodes of the vertical transfer CCD and the horizontal transfer CCD; and a step of forming second transfer electrodes between the first transfer electrodes of the vertical transfer CCD and the horizontal transfer CCD.
