Title:
SEMICONDUCTOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/147222
Kind Code:
A1
Abstract:
This semiconductor device is provided with a substrate, a light emitting element, a light detection means, a case, a light transmitting member and a light blocking layer. The substrate has a main surface and a back surface. The light emitting element is mounted on the main surface of the substrate. The light detection means is mounted on the main surface at a distance from the light emitting element. The light detection means comprises a first detection part that detects light emitted from the light emitting element. The case surrounds the light detection means, while being supported by the main surface. The light transmitting member has an inner surface that faces toward the main surface and an outer surface that faces toward a direction which is opposite to the direction toward which the inner surface faces. The light transmitting member is supported by the case at a distance from the light detection means in the thickness direction of the substrate. The light blocking layer is provided on the light transmitting member and blocks light in the wavelength range that corresponds to the light emitted from the light emitting element. The light blocking layer is provided with a first opening that faces the first detection part when viewed from the thickness direction of the substrate.
