Abstract
Provided are a complementary metal oxide semiconductor (CMOS) image sensor and a method of fabricating the same, where the CMOS image sensor includes a photodiode, a drive transistor, a reset transistor, and a selection transistor; the drive transistor includes a threshold voltage adjustment region doped with impurities of a type substantially identical to that of impurities doped into a source and a drain of the drive transistor; and the CMOS image sensor includes pixels with expanded output signal ranges.
