IMAGE SENSOR

The invention provides an image sensor which includes: a substrate; color filter units disposed on the substrate; and a grid structure disposed on the substrate and surrounding each of the color filter units. The grid structure includes: a first partition wall, disposed on the substrate, located between the color filter units; and a second partition wall, disposed directly on the first partition wall, located between the color filter units. A top width of the second partition wall is smaller than a bottom width of the second partition wall. 本发明提出一种图像感测器。图像感测器包括基底、彩色滤光单元以及网格结构，彩色滤光单元设置于基底上；网格结构设置于基底上，且围绕彩色滤光单元的每一个。网格结构包括：第一隔墙，设置于基底上，位于彩色滤光单元之间；以及第二隔墙，设置于第一隔墙的正上方，位于彩色滤光单元之间。第二隔墙的顶宽度小于第二隔墙的底宽度。
