Abstract
A solid-state image sensor including a photoelectric conversion region partitioned by trenches, a first semiconductor region surrounding the photoelectric conversion region, a first contact in contact with the first semiconductor region at a bottom portion of the trench, a first electrode in contact with the first contact in the first trench, a second semiconductor region in contact with the first semiconductor region having the same conductive type as the first semiconductor region, a third semiconductor region in contact with the second semiconductor region, between the second semiconductor region and a first surface, and having a second conductive type, a second contact on the first surface in contact with the third semiconductor region, and a second electrode in contact with the second contact, and a second surface at which the first contact and the first electrode are in contact with each other is inclined with respect to the first surface.
