IMAGE SENSOR AND METHOD OF FORMING THE SAME

摘要

PURPOSE: An image sensor and a manufacturing method thereof are provided to prevent cross-talk by blocking light which is entered from a pixel region by including a light-shield pattern. CONSTITUTION: A substrate comprises a pixel region(PIR) and a pad area(PAR). A through via penetrates the substrate in the pad region. A plurality of unit pixels(52) is arranged in the pixel region. A light-shield pattern is arranged between the unit pixels in the pixel region. The through via and the light-shield pattern comprise same material.
