Imaging element and imaging device

摘要

An imaging element includes: a semiconductor substrate in which a plurality of pixels is arranged in a two-dimensional array; a color filter layer which is laminated in a position corresponding to the pixel on an upper layer of the semiconductor substrate; a plurality of micro lenses which is laminated on an upper layer of the color filter layer to condense light which is incident onto the pixel; and an isolated columnar reflective wall which is vertically provided in an intermediate layer between the semiconductor substrate and the micro lens at every position of a gap enclosed by the plurality of adjacent micro lenses and reflects the light which is incident onto the color filter from the gap to a direction facing the pixel corresponding to the color filter.

1. An imaging element, comprising:
a semiconductor substrate in which a plurality of pixels is arranged in a two-dimensional array; a color filter layer which is laminated in a position corresponding to the pixel on an upper layer of the semiconductor substrate; a plurality of micro lenses which is laminated on an upper layer of the color filter layer to condense light which is incident onto the pixel; and an isolated columnar reflective wall which is vertically provided in an intermediate layer between the semiconductor substrate and the micro lens at every position of a gap enclosed by adjacent three or more of the micro lenses and reflects the light which is incident onto the color filter from the gap to a direction facing the pixel corresponding to the color filter.
