Claim:
1. An image sensor, comprising: a first substrate having a first surface and a second surface opposed to the first surface, the first substrate being divided into a first region, a second region surrounding the first region, a third region surrounding the second region and a fourth region surrounding the third region; a photodiode array disposed in the first substrate adjacent to the first surface, the photodiode array including first photodiodes in the first region, second photodiodes in the second region and third photodiodes in the third region; a first wiring structure disposed in the first region on the first surface of the first substrate, the first wiring structure being electrically connected to the first photodiodes; a second wiring structure disposed in the second region on the first surface of the first substrate, the second wiring structure including a power supply wiring; a third wiring structure disposed in the third region on the first surface of the first substrate, the third wiring structure being electrically connected to the third photodiodes; and a light blocking layer pattern disposed on the second surface of the first substrate, the light blocking layer pattern covering the third region and the fourth region.
