Classification: CPC H | IPC H

Claim 8:
9. An imaging apparatus, comprising:
a light detecting device; and
a signal processing circuit configured to process a signal from the light detecting device, wherein
the light detecting device includes:
a semiconductor substrate on which a plurality of photoelectric conversion devices is arranged in an imaging device region in a two-dimensional array; and
a stacked body comprising a plurality of layers stacked on the semiconductor substrate,

the plurality of layers includes:
an in-layer lens layer that comprises a plurality of in-layer lenses and a plurality of structures, wherein
each in-layer lens of the plurality of in-layer lenses is at a first position corresponding to each photoelectric conversion device of the plurality of photoelectric conversion devices,
the plurality of structures is at a height equal to a height of the plurality of in-layer lenses, and
the plurality of structures is on an outside of the imaging device region;

a planarization layer that is stacked on the in-layer lens layer and that has a planarized surface; and
an on-chip lens layer that is an upper layer than the planarization layer and that comprises a plurality of on-chip lenses,

each on-chip lens of the plurality of on-chip lenses is at a second position corresponding to each photoelectric conversion device of the plurality of photoelectric conversion devices, and
in a plan view, a first region in which the plurality of on-chip lenses is provided is smaller than a second region in which the plurality of in-layer lenses and the plurality of structures are provided.
