IMAGE SENSOR HAVING PIXEL ISOLATOR AREA

摘要

Disclosed is an image sensor having a pixel isolation region. The image sensor includes a semiconductor substrate, a plurality of unit pixel regions for light-conversing an incident light upon a surface of the semiconductor substrate, and a pixel isolation region positioned between the adjacent unit pixel regions. The pixel isolation region includes an impurity region formed by implanting an ion into the substrate for shielding a leakage current generated between the adjacent unit pixel regions and a light shielding film formed on a surface of the impurity region for preventing the incident light from diffusing into the adjacent unit pixel region.
