Abstract

An example of an optical device of the present disclosure includes a substrate, an obverse-surface conductive layer, a reverse-surface conductive layer, a first conductive part, an optical element and a reflector. The first conductive part extends through the substrate and overlaps with a first obverse-surface conducting region of the overse-surface conductive layer and the reverse-surface conductive layer as viewed in a thickness direction of the substrate. The reflector has an inner surface that surrounds the optical element as viewed in the thickness direction. The optical element is located on first obverse-surface conducting region, and the second obverse-surface conducting region is located between the first obverse-surface conducting region and the inner surface of the reflector as viewed in the thickness direction. A second obverse-surface conducting region of the overse-surface conductive layer is spaced apart from the inner surface of the reflector as viewed in the thickness direction.

Dependent claims

A semiconductor device comprising:

a substrate including an obverse surface, a reverse surface and a side surface that connects the obverse surface and the reverse surface to each other, the substrate being formed with a recess that recedes from the side surface in plan view, the recess having an inner side face extending from the obverse surface to the reverse surface;
an obverse electrode disposed on the obverse surface;
a reverse electrode disposed on the reverse surface;
an intermediate electrode disposed on the inner side face of the recess and electrically connecting the obverse electrode and the reverse electrode to each other;
and
a semiconductor element disposed on the obverse electrode,
wherein the obverse electrode includes a peripheral edge that is offset inwards of the obverse surface with respect to a boundary between the obverse surface and the side surface, and
the reverse electrode includes a peripheral edge that is offset inwards of the reverse surface with respect to a boundary between the reverse surface and the side surface.
