摘要:
The inventive concepts provide an auto-focus image sensor and a digital image processing device including the same. The auto-focus image sensor includes a substrate including at least one first pixel used for detecting a phase difference and at least one second pixel used for detecting an image, a deep device isolation portion disposed in the substrate to isolate the first pixel from the second pixel, and a light shielding pattern disposed on the substrate of at least the first pixel. The amount of light incident on the first pixel is smaller than the amount of light incident on the second pixel by the light shielding pattern.

A complementary metal-oxide-semiconductor (CMOS) image sensor is provided. The CMOS image sensor may include an epitaxial layer having a first conductivity type and having first and second surfaces, a first device isolation layer extending from the first surface to the second surface to define first and second pixel regions, a well impurity layer of a second conductivity type formed adjacent to the first surface and formed in the epitaxial layer of each of the first and second pixel regions, and a second device isolation layer formed in the well impurity layer in each of the first and second pixel regions to define first and second active portions spaced apart from each other in each of the first and second pixel regions.
