Abstract
A complementary metal-oxide-semiconductor (CMOS) image sensor and a method for fabricating the same are provided. The CMOS image sensor includes: a pixel region provided with a plurality of unit pixels, each including a buried photodiode and a floating diffusion region; and a logic region provided with CMOS devices for processing data outputted from the unit pixels, wherein a self-aligned silicide layer is formed on gate electrodes and source/drain regions of the CMOS devices in the logic region while a self-aligned silicide blocking layer is formed over the pixel region.
