Abstract
A semiconductor device is provided. The semiconductor device includes a substrate having a photoelectric conversion element, a first light-shielding layer disposed on the substrate and having a first aperture, a light-transmitting layer disposed on the first light-shielding layer, at least one second light-shielding layer disposed in the light-transmitting layer and having a second aperture, and a light-condensing structure disposed on the light-transmitting layer. The orthogonal projection of the second aperture on the bottom surface of the substrate has a long axis of symmetry and a short axis of symmetry perpendicular to the long axis of symmetry.
