Abstract
In a solid state image sensor which has two photodiodes juxtaposed in a predetermined direction in each pixel and is formed by carrying out divided exposure, that is, exposure treatment of an entire chip by a plurality of times of exposure, image quality is improved and autofocusing speed is increased. Provided is a solid state image sensor having a first exposure region having a first region and a second exposure region having a second region. They overlap with each other in a third region between the first and second regions. In a pixel formed in the third region, a photodiode formed through a mask for first exposure region is placed at a position closer to the side of the second region than another photodiode formed through a mask for second exposure region is.
