Abstract: A semiconductor device includes a semiconductor substrate, a photoelectric conversion element, a first isolation insulating film, and a current blocking region. The first isolation insulating film is formed around the photoelectric conversion element. The current blocking region is formed in a region between the photoelectric conversion element and the first isolation insulating film. The current blocking region includes an impurity diffusion layer, and a defect extension preventing layer disposed in contact with the impurity diffusion layer to form a twin with the impurity diffusion layer. The defect extension preventing layer has a different crystal structure from that of the impurity diffusion layer. At least a part of the current blocking region is disposed in contact with the first isolation insulating film.

Abstract: Provided are a semiconductor device capable of detecting a light of each color with high accuracy without using a color filter, particularly enhancing detection accuracy of charges obtained by photoelectric conversion of a long-wavelength light, and manufacturing and control methods thereof. The semiconductor device has a p type semiconductor substrate, and first, second and third pixel regions. These regions each include a p type well region in the p type semiconductor substrate and an n type region configuring a pn junction therewith. The p type well region of the first pixel region is thinner, from the main surface to the lowermost portion, than that of the second and third pixel regions. On the side opposite to the main surface of the p type well region of the first and second pixel regions, a buried p type well region contiguous to the p type well region is further placed.
