Abstract: The present disclosure discloses an optical module package structure and method thereof. The optical module includes a substrate, a shield, a photosensitive unit and a cover. The shield is disposed on the top of the substrate and forms a first housing space with the upper surface of the substrate. The photosensitive unit is disposed on the substrate and located in the first housing space. The shield has a light-receiving part above the photosensitive unit. At least one notch is on the outer surface of the shield. A cushion is disposed on the notch and protrudes on the upper surface of the shield. The cover is disposed on the cushion(s) and kept a constant distance to the upper surface of the shield by contacting with the cushion(s).

Abstract: There is provided an optical sensor package including a substrate, a base layer, an optical detection region, a light source and a light blocking wall. The base layer is arranged on the substrate. The light detection region and the light source are arranged on the base layer. The light blocking wall is arranged on the base layer, and located between the light detection region and the light source to block light directly propagating from the light source to the light detection region.
