Abstract
An image sensing device is provided to include a pixel array including unit pixels. Each unit pixel includes a substrate including a sensing region that generates charge carriers in response to incident light, first and second signal detectors configured to receive control signals for generating a charge current in the sensing region of the substrate and capture the charge carriers moving by the charge current, a lens layer disposed to direct incident light toward the substrate in the unit pixel, and a noise blocking structures disposed over a peripheral region of the sensing region and underneath the lens and structured to leave space above the sensing region open to allow the incident light from the lens layer to reach the sensing region while shield a peripheral region of the sensing region in the substrate from the incident light.
