An image sensor and a manufacturing method thereof are provided to remove the leakage and noise between the pixel array and the peri region by increasing the electrical isolation effect between the peri region and the pixel array. An image sensor is comprised of a pixel array including the photo diode and a peripheral region including a logic circuit. The pixel array is the light accepting region receiving the light from the image sensor. The peri region is the region processing only the electric signal. The electrical isolation effect between the epi layers of the pixel array and the peri region is improved by using a red isolating region(220), the first plug isolating region(240), and a vertical structure of the green isolating region(250). The first isolating region(260) comprises the red isolating region, the first plug isolating region, and the green isolating region.
