Image sensor and method of fabricating the same
An image sensor and a method of fabricating the same are provided. A pad region is disposed on a substrate. The pad region has a higher concentration of impurity ions than the substrate. The pad region is selectively removed using the substrate as an etch mask, thereby forming a hole. A conductive pad is formed in the hole of the substrate.
