Abstract
An image sensor structure and manufacturing method thereof are provided. The image sensor structure includes a substrate with a first surface. A first doped region of a first conductivity type is in the substrate and under the first surface. A second doped region of a second conductivity type is in the substrate and under the first surface. A gate structure is on the first surface of the substrate and overlapping a boundary of the first doped region and the second doped region. The epitaxial structure is on the first surface of the substrate. A method for manufacturing an image sensor structure is also provided.
