| Summary: | Disclosed are a complementary metal oxide semiconductor (CMOS) image sensor and a method for fabricating the same, which are capable of effectively preventing a cross talk effect. The CMOS image sensor includes a semiconductor substrate; device isolation regions provided on the semiconductor for defining device regions therebetween; photocharge generating portions provided on the device regions for receiving external light and for generating and storing electric charges; light concentrating portions provided over the photocharge generating portions for concentrating the external light onto corresponding photocharge generating portions; and cross talk preventing portions for preventing the light passing through the light concentrating portions from being incident onto adjacent photocharge generating portions. |
