Abstract: The present disclosure relates to an image sensor and a method of forming the same, and an image forming device. An image sensor includes: a substrate in which a photosensitive element region is formed; and a first light concentrating portion formed in a peripheral region of the photosensitive element region, wherein the first light concentrating portion is formed such that to the light entering the peripheral region of the photosensitive element is refracted toward the photosensitive element region through the light concentrating portion. The image sensor and method for forming an image sensor of the present disclosure allow more light to enter the area of the photosensitive element in the substrate, thereby improving the light sensitivity of the image sensor.

Abstract: The present disclosure relates to an image sensor comprising: a photodiode; a color filter located above the photodiode; and a converging lens located between the photodiode and the color filter, wherein the converging lens is configured to converge light onto the photodiode. The image sensor can make the configuration of the image sensor more compact while preventing crosstalk of light between pixel cells.
