  • Publication number: 20230362509
    Abstract: A step of forming an on-chip lens of a phase difference pixel is simplified. An imaging element includes a pixel array unit, an individual on-chip lens, a common on-chip lens, and an adjacent on-chip lens. In the pixel array unit, pixels that performs photoelectric conversion according to incident light components, a plurality of phase difference pixels that is included in the pixels, is arranged adjacent to each other, and detects a phase difference, and phase difference pixel adjacent pixels that are included in the pixels and are adjacent to the phase difference pixels are arranged two-dimensionally. The individual on-chip lens is arranged for each of the pixels and individually condenses the incident light components on corresponding one of the pixels. The common on-chip lens is commonly arranged in the plurality of phase difference pixels and commonly condenses the incident light component.
