Image sensor and method for manufacturing thereof
An image sensor is provided including a substrate, an array of photosensitive units, a grid, a light-tight layer and a plurality of color filters. In the image sensor, the grid has a top surface, and the light-tight layer is disposed on the top surface of the grid. Due to the light-tight layer on the grid, an incident light entering into the grid can be blocked by the light-tight layer, so that the crosstalk effect is reduced significantly. Further, a method for manufacturing the image sensor also provides herein.
