摘要：The present invention relates to an isolation layer for CMOS image sensor and afabrication method thereof, which are capable of improving a low light level characteristicof the CMOS image sensor. The isolation layer includes: a field insulating layer formed on

a predetermined portion of a substrate in the logic area to thereby define an active areaand a field area; a field stop ion implantation area formed on a predetermined portion ofthe substrate in the pixel area, the field stop ion implantation area having a

predetermined depth from a surface of the substrate to define an active area and a fieldarea; and an oxide layer deposited on a substrate surface corresponding to the field stopion implantation area.
