Abstract

Abstract Translated from Japanese 【課題】撮像画像の画像品質を向上させる。 【解決手段】半導体基板101の画素分離部301に形成されたトレンチTRの内部に第1遮光部313Aを設ける。これと共に、その第1遮光部313Aの上面側に第2遮光部313Bを設ける。ここでは、画素領域PAの中心よりも周辺において、第2遮光部313Bの中心が、画素分離部301の中心に対して、画素領域PAの周辺の側へ多くシフトするように、第2遮光部313Bを形成する。つまり、少なくとも第2遮光部について「瞳補正」を実施する。 【選択図】図5 An image quality of a captured image is improved. A first light shielding portion 313A is provided inside a trench TR formed in a pixel separation portion 301 of a semiconductor substrate 101. At the same time, a second light shielding part 313B is provided on the upper surface side of the first light shielding part 313A. Here, in the periphery of the pixel area PA, the second light-shielding part 313B is shifted so that the center of the second light-shielding part 313B is more shifted toward the periphery of the pixel area PA than the center of the pixel separation part 301. 313B is formed. That is, “pupil correction” is performed on at least the second light-shielding portion. [Selection] Figure 5
