Abstract:
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.

Claim (Index 1):
An auto-focus image sensor comprising:\n a substrate including at least one first pixel configured to detect a phase difference and at least one second pixel configured to detect an image; a deep device isolation portion in the substrate configured to isolate the at least one first pixel from the at least one second pixel; and a light shielding pattern on the substrate of at least the first pixel, wherein 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, wherein the substrate includes, a first surface on which a gate electrode is disposed, and a second surface opposite to the first surface, and wherein the deep device isolation portion is adjacent to at least the second surface, wherein the deep device isolation portion includes, a first deep device isolation portion adjacent to the first surface and a second deep device isolation portion adjacent to the second surface, and wherein the second deep device isolation portion contacts the first deep device isolation portion.
