Abstract
A method of fabricating an image sensor includes forming a semiconductor substrate of a first conductivity type, forming a pixel isolation trench in in the semiconductor substrate to define pixel regions, forming a liner insulating layer in the pixel isolation trench, doping the liner insulating layer with dopants of a first conductivity type, forming a semiconductor layer on the liner insulating layer to fill the pixel isolation trench after the doping of the dopants, and performing a thermal treatment process on the semiconductor substrate.
