CMOS IMAGE SENSOR

摘要

A cmos image sensor is provided to prevent the uniformity of photo diode property by forming a conductive line arranged on an active region in relation to a light block layer. In a cmos image sensor, a pixel array includes a first pixel obtaining an effective pixel and a second pixel which is not used as an effective pixel. A conductive line(220) consisting of at least one layer is arranged on a first conductive region. Light block layers(240,250) are arranged on a second conductive region in correspondence to the second pixel. A first pixel supplies a signal and outputs it through a conductive line(230) arranged on the second conductive line. The pixel array is composed of the effective region and an optical block region where the second pixel is arranged.
