摘要：
The present invention provides a light shield for shielding the floating diffusion of a complementary metal-oxide semiconductor (CMOS) imager. In accordance with an embodiment of the present invention, there is provided a pixel sensor cell including: a device region formed on a substrate; and a first layer of material forming a sidewall adjacent to a side of the device region for blocking electromagnetic radiation from the device region.
