摘要 |
An optical device according to an aspect of the present invention includes: a semiconductor substrate layer including a plurality of elements; at least one optical component which is formed at the first principal surface side of the semiconductor substrate layer and transmits incident light of desired wavelength; and an interconnect layer formed on second principal surface of the semiconductor substrate layer. In the semiconductor substrate layer, (i) a photoelectric conversion element region is formed at a position corresponding to the at least one optical component, and (ii) at least one element among the plurality of elements is formed near the second principal surface. At least a part of the at least one optical component is formed as a part of the semiconductor substrate layer, and the interconnect layer includes the conductive material electrically connected to the photoelectric conversion element region and the at least one element.
