Abstract:
A pixel cell and imager device, and method of forming the same, where the pixel cell has a plurality of metallization and via layers formed over a photosensitive region. The metallization and via layers form a step-like light tunnel structure that augments the photosensitive region's ability to capture light impinging on the photosensitive region.
