Abstract
A method of fabricating an image sensor device includes forming an insulating layer on a substrate including a photodiode therein, and forming a wiring structure on the insulating layer. The wiring structure includes at least one wiring layer and at least one insulating interlayer. A cavity is formed extending into the wiring structure over the photodiode to expose a surface of the at least one insulating interlayer. The surface of the at least one insulating interlayer exposed by the cavity is modified to define a hydrophobic surface. Related systems and devices are also discussed.
