Abstract
An image sensing device is provided to include: a substrate having a first surface on which light is incident and a second surface facing the first surface; a plurality of detection structures, each comprising a control node configured to exhibit a conductivity type and generate a potential gradient in the substrate, and a detection node configured to capture photocharge which is generated in response to incident light and migrates in response to the potential gradient; and a first well area disposed to abut the control nodes of the plurality of detection structures and containing an impurity with a different conductivity type from the conductivity type of the control nodes.
