Semiconductor device and method for manufacturing same

A semiconductor device, comprising:

• an interconnect layer;
• an electrical element, a direction from the interconnect layer toward the electrical element being a first direction;
• an optical element, a direction from the interconnect layer toward the optical element being aligned with the first direction, a second direction from the electrical element toward the optical element crossing the first direction;
• and
• a resin portion including a first partial region, the first partial region being between the electrical element and the optical element,
• at least a portion of the optical element not overlapping the resin portion in the first direction,
• the first partial region having a first resin portion surface and a second resin portion surface, the second resin portion surface being opposite to the first resin portion surface and opposing the interconnect layer,
• the optical element having a first optical element surface and a second optical element surface, the second optical element surface being opposite to the first optical element surface and opposing the interconnect layer, the optical element including at least one of a light emitter or a light receiver, the at least one of the light emitter or the light receiver being provided at the second optical element surface,
• a distance along the first direction between the interconnect layer and the first resin portion surface being longer than a distance along the first direction between the interconnect layer and the first optical element surface.
