Abstract
In each pixel having a plurality of photodiodes for one microlens of a plurality of pixels arranged in a pixel array part, the photoelectrically converted electrons are prevented from moving between the photodiodes, thereby to improve the electron isolating characteristic, resulting in improved performances of a semiconductor device. In a well region immediately under between a first Ntype semiconductor region forming a first photodiode in a pixel and a second Ntype semiconductor region forming a second photodiode in the pixel, an isolation region higher in impurity density than the well region is formed.
