Title: METHOD FOR MANUFACTURING OPTICAL SENSOR ARRANGEMENTS AND HOUSING FOR AN OPTICAL SENSOR
Abstract:
A method for manufacturing optical sensor arrangements (10) is provided. The method comprises providing at least two optical sensors (11) on a carrier (12) and providing a cover material (14) on the side of the optical sensors (11) facing away from the carrier (12). The method further comprises providing an aperture (13) for each optical sensor (11) on a top side (15) of the cover material (14) facing away from the carrier (12) and forming at least one trench (16) between the optical sensors (11) from the carrier (12) towards the top side (15) of the cover material (14), the trench (16) comprising inner walls (18). Moreover, the method comprises coating the inner walls (18) with an opaque material (19), such that an inner volume (20) of the trench (16) is free of the opaque material (19), and singulating of the optical sensor arrangements (10) along the at least one trench (16). Furthermore, a housing for an optical sensor is provided.
