Patent ID: 7453130

Claim:
A semiconductor apparatus comprising: a light input/output portion provided in an upper portion of a semiconductor substrate, the light input/output portion having an opening region for light associated to the light input/output portion to pass through, the opening region having a central axis and being bounded by a light shielding layer; a transparent film covering and contacting the opening region, said transparent layer having an upper surface opposite the opening region, wherein said upper surface has a concave region formed therein above the opening region; and an interlayer lens provided on the concave region formed in the upper surface of the transparent film, the interlayer lens positioned such that an optical axis of the interlayer lens is aligned with the central axis of the opening region, so that the optical axis of the interlayer lens and the central axis of the opening region are parallel and matched, wherein the light shielding layer is asymmetric with respect to the central axis of the opening region, as viewed from a cross-section of the semiconductor apparatus, said central axis being perpendicular to the surface of the semiconductor substrate.
