Abstract
An image sensor pixel includes a substrate, an epitaxial layer, and a light collection region. The substrate is doped to have a first conductivity type. The epitaxial layer is disposed over the substrate and doped to have a second conductivity type opposite of the first conductivity type. The light collection region is disposed within the epitaxial layer for collecting photo-generated charge carriers. The light collection region is doped to have the first conductivity type as well.
