Abstract: An optical sensor arrangement comprises an optical barrier which is placed between a light-emitting device and a photodetector. Herein the light-emitting device and the photodetector are arranged on a first plane and are covered by a cover. The photodetector exhibits an active zone. The optical barrier exhibits an extent along a first principal axis, which is pointing parallel to the line connecting the centers of the light-emitting device and the photodetector. Herein the extent is greater than a dimension of the active zone. The optical barrier is designed to block light emitted by the light-emitting device that otherwise would be reflected by the cover by means of specular reflection and would reach the photodetector. The optical barrier is designed to pass light emitted by the light-emitting device and scattered on or above an outer surface of the cover.

Abstract: An optical proximity sensor arrangement comprises a semiconductor substrate (100) with a main surface (101). A first integrated circuit (200) comprises at least one light sensitive component (201). The first integrated circuit is arranged on the substrate at or near the main surface. A second integrated circuit (300) comprises at least one light emitting component (301), and is arranged on the substrate at or near the main surface. A light barrier (400) is arranged between the first and second integrated circuits. The light barrier being designed to block light to be emitted by the at least one light emitting component from directly reaching the at least one light sensitive component. A multilayer mask (500) is arranged on or near the first integrated circuit and comprising a stack (501) of a first layer (502) of first elongated light blocking slats (503) and at least one second layer (504) of second elongated light blocking slats (505). The light blocking slats are arranged in the mask to block light, incident on the mask from a first region of incidence (701), and to pass light, incident on the mask from a second region of incidence (702), from reaching the at least one light sensitive component.
