    摘要： An image sensor includes a semiconductor layer including a first section and a second section, the semiconductor layer having a first surface and a second surface that face each other; a device isolation layer in the semiconductor layer and defining a plurality of pixels; a first grid pattern on the first surface of the semiconductor layer over the first section; and a light-shield pattern on the first surface of the semiconductor layer over the second section. A top surface of the first grid pattern is located at a first level, a top surface of the light-shield pattern is located at a second level, the first level is lower than the second level, and the first and second levels are defined with respect to the first surface of the semiconductor layer.

    摘要： A device includes first patterns, second patterns, and a second sample pattern on a semiconductor substrate. The second patterns are horizontally spaced apart at an equal interval from the second sample pattern. The second sample pattern includes first and second sidewall facing each other, a first point on the first sidewall, and a second point on the second sidewall. The second sample pattern and the most adjacent first pattern in relation to the second sample pattern are spaced apart from each other at a first horizontal distance in a direction parallel to a line connecting the first point and the second point. The first horizontal distance is greater than a second horizontal distance in the direction between one second pattern of the second patterns and a most adjacent first pattern in relation to the one second pattern.

    摘要： An image sensor in which a shading phenomenon is decreased and the quality is increased is provided. The image sensor includes a light-receiving region including a plurality of unit pixels. The image sensor further includes a first region with unit pixels adjacent to a center of the light-receiving region, and a second region with the unit pixels spaced apart from the center of the light-receiving region. In both regions, a plurality of color filters corresponding to the plurality of unit pixels is disposed on a first face of the substrate, as well as a grid pattern interposed between the plurality of color filters defining boundaries between the unit pixels. A width of the grid pattern in the second region is greater than a width of the grid pattern in the first region, thereby adjusting light receiving areas near the edge of the image sensor to correct for a shading phenomenon.
