ABSTRACT:
A complementary metal oxide semiconductor (CMOS) image sensor layout structure is described. The CMOS image sensor layout structure includes a substrate, a plurality of light sensing devices, a plurality of transistors and a plurality of color-filtering film layers. The substrate has a pixel array region comprising a plurality of pixels. Each pixel has a light sensing region and an active device region. The pixels are isolated from one another by isolation structures and the light sensing regions have different sizes. The light sensing devices are defined separately within the respective light sensing regions. The transistors are disposed within the respective active device region. The color-filtering film layers are disposed separately above the pixels to form a color-filtering array.
