Optical sensor device and manufacturing method thereof

Abstract

An optical sensor device includes a substrate, a light-receiving element, a first light-emitting element, a second light-emitting element, a first encapsulating structure, a second encapsulating structure and a shielding structure. The light-receiving element, the first light-emitting element and the second light-emitting element are disposed over the substrate. The first encapsulating structure covers the light-receiving element, and the second encapsulating structure covers the first light-emitting element and the second light-emitting element. The shielding structure encloses the light-receiving element, the first light-emitting element, the second light-emitting element, the first encapsulating structure and the second encapsulating structure. A method of manufacturing an optical sensor device includes: arranging a light-receiving element, a first light-emitting element and a second light-emitting element on a substrate; adhering a shielding structure to the substrate; forming a first encapsulating structure to cover the light light-receiving element; and forming a second encapsulating structure to cover the first light-emitting element and the second light-emitting element.
